Veeco News: MBE Systems Installed For Quantum Research

Veeco Accelerates Quantum Research with Denmark and South Korea MBE Deployments

Veeco News

Veeco Instruments Inc., a leader in advanced semiconductor and compound semiconductor process equipment, has solidified its position in the rapidly growing quantum technology field with key new MBE system triumphs. The new facilities at Yeungnam University in South Korea and Sparrow Quantum in Denmark demonstrate the global commitment to developing quantum computing and communication materials.

These deployments improve Veeco's reputation as a trusted quantum innovation enabler. With these acquisitions, the company has over 30 MBE systems for R&D and quantum technology development worldwide. The accurate production of quantum devices requires cutting-edge tools that handle material layers down to the atomic level, which MBE technology excels at.

Precision Engineering: Veeco Systems Selected for Cutting-edge Research

Both deployments highlight unique but crucial quantum research topics.

Danish quantum photonics leader Sparrow Quantum chose Veeco's cutting-edge GENxcel R&D MBE equipment. The development of high-performance quantum dot single-photon emitters (SPEs) will benefit from this approach.

SPEs are necessary for making quantum hardware. As safe quantum communication networks and photonic quantum computers require controlled and reliable single photon emission, the partnership will aid these disciplines. The GENxcel system's high material quality and fast research cycles helped Sparrow Quantum accelerate its transition from experimental designs to commercial-grade quantum components.

The system's strategic placement in Denmark is notable. By using its physics and photonics expertise, the Netherlands is becoming a European leader in quantum communication and photonic quantum computing. Veeco will directly create photonic chips and quantum communication protocols for unbreakable communication networks and fast computer architectures through this collaboration.

Yeungnam University in South Korea is using Veeco's GEN10 MBE technology to boost its research. This technology will help the institution explore quantum dot and nanostructure properties more deeply. This study supports many quantum technology efforts. Innovative sensor designs and durable solid-state quantum memory components are conceivable uses. For educational institutions with large research requirements, the GEN10 system is ideal due to its scalability and ability to support a wide range of materials science applications.

This expansion in MBE capabilities helps South Korea quickly mobilise resources to lead fundamental quantum research and semiconductor manufacturing through Yeungnam University. This ensures a pool of highly skilled engineers with material expertise who can apply innovative research.

The Atomic-Scale Molecular Beam Epitaxy Imperative These pioneers' choice of MBE devices shows the technology's unmatched potential in quantum materials science. Ultra-high vacuum (UHV) molecular beam epitaxy creates thin films of single-crystal materials layer by atomic layer.

Heating elemental source materials in the MBE chamber's vacuum produces atom or molecule beams. Once on a substrate without barriers, these beams condense and form a highly organised crystalline structure. This slow-growth, in situ monitoring technology lets researchers carefully control material composition and thickness. In addition to being desirable, quantum device manufacture requires this level of control.

Quantum devices like Sparrow Quantum and Yeungnam University's quantum dots capture electrons or excitons in tiny structures to use quantum phenomena. At this level, even a minor crystal lattice imperfection can destroy the fragile quantum coherence, rendering the gadget useless.

According to Matthew Marek, Senior Director of Marketing for Veeco's MBE Product Line, the victories show Veeco's commitment to quantum computing through precision thin-film deposition. He said the company's solutions are “trusted by top quantum innovators worldwide for delivering the material quality, process control, and scalability essential to push the boundaries of quantum materials, from early-stage R&D to scalable device production”.

Critical Role in a Growing Global Market These deployments correlate with a dramatic rise in global government and private quantum technology ecosystem investment. McKinsey estimates $2 billion was invested in quantum computing companies in 2024.

Public investment announcements, which often reflect national strategies, reached 10 billion in early 2025, which is even more surprising.

As worldwide momentum increases to address the complex materials science difficulties that are preventing mainstream quantum commercialisation, Veeco is working with top quantum inventors. Veeco's cutting-edge MBE and atomic layer deposition solutions help researchers push quantum gadget performance, scalability, and commercial feasibility.

Veeco's ability to deliver the specialized equipment needed to create these complex materials is a strategic enabler of worldwide quantum strategies and an economic success. In a market that is rapidly shaping information security and computation, the organization helps entrepreneurs solve complex materials science challenges.

Sparrow Quantum gets €27.5M for Photonic Quantum Computing

Sparrow Quantum Secures Record €27.5M to Industrialise Photonic Quantum Chips

Sparrow Quantum, a Danish startup founded by the Niels Bohr Institute, raised a record €27.5 million ($32 million USD) in Series A funding, boosting European deep-tech and quantum technologies. This capital infusion, the largest quantum technology investment in the Nordics, shows investor confidence in advanced photonic quantum computer hardware's commercial feasibility.

Key investors were Jacob Jakobsen Gruppen ApS, Scale Capital, North Ventures, and LIFTT EuroInvest, which invested heavily. LIFTT EuroInvest is heavily backed by the EIB and LIFTT. Institutional and strategic funding helped the company develop from a scientific breakthrough organisation into an industrial-scale enterprise ready to change quantum hardware worldwide.

The Determined Heart of Quantum Computing

Sparrow Quantum's ambitions centre on the deterministic photonic chip Sparrow Core. It's critical because this technology overcomes the unreliability and uncertainty of conventional single-photon sources, one of quantum computing's biggest obstacles.

Sparrow Core produces identical photons. Photons are the “flying qubits,” or building blocks, of light-based quantum systems. Sparrow Quantum's deterministic photon production is on demand. Building robust quantum communication networks and fault-tolerant quantum processors need this capacity.

Sparrow Quantum, a conventional deep-tech success story, is rooted in the Niels Bohr Institute at the University of Copenhagen's quantum research background. The business was able to solve the single-photon source difficulty because Professor Peter Lodahl's team turned decades of basic physics into a marketable hardware solution.

An advantage of ambient temperatures

The company's photonic platform's many benefits are key to its business model. Sparrow Quantum's chips work reliably at room temperature, unlike superconducting circuits or trapped ions, which require extremely cold, complex cryogenic settings near absolute zero.

Functioning at normal temperature is crucial. This eliminates cryogenic cooling infrastructure's size, cost, and logistical challenges. This makes device miniaturisation and scalable inclusion onto microchips easy and practical. Light-based qubits have the high fidelity and endurance needed for industrial-grade quantum applications because they are less sensitive to external noise.

Professor and industry specialist Peter Lodahl, founder and CQO, stressed the company's major change. Lodahl said “we have moved beyond that” for years, but science has remained the focus. He said the Sparrow Core is "industrialised," ready for mass production, and used by European IT giants. Lodahl said the company is focused on “making this crucial, enabling technology widely available across the global quantum ecosystem, scaling up, and refining the manufacturing processes.” He called the new cash “rocket fuel for that scaling phase”.

Strategic Record Capital Use

Three key pillars will receive €27.5 million strategically.

The investment will first pay for the large manufacturing capacity increase needed to meet demand. Large-scale production of high-quality, deterministic photonic devices requires specialised fabrication methods. Money will secure infrastructure and expertise for growth.

Second, many funds will establish worldwide firms. This project will target key quantum markets in Asia and North America, where trustworthy quantum hardware is in high demand.

Finally, the finance secures the Sparrow Core technology generation R&D pipeline. In the fast-paced race of quantum advancement, creativity is required. Future research and development will combine more deterministic sources on a chip to boost device complexity. R&D will also improve entanglement fidelity and photon indistinguishability. All of these breakthroughs are necessary for universal quantum computation.

Keeping Europe in Quantum Race

Beyond a financial transaction, the investment represents a political move to place Denmark and the EU in the global quantum technology race. Geopolitical competition over essential technologies makes supply chain control for quantum hardware components like the deterministic source a national and regional security risk.

Europe aspires to build a strong, industrial-scale indigenous producer to capitalise on its technical momentum and reduce its dependence on outside supply. Academic spin-outs are crucial to regional competitiveness in high-stakes technology fields and commercialising unique European research, as shown by the company's success.

Scaling has huge market implications. Even though the immediate use case is the study and development of general-purpose quantum computers, the Sparrow Core technology enables Quantum Key Distribution (QKD) and quantum networking. Secure communication requires a continuous stream of single photons to encode and transfer cryptographic keys. By providing a scalable, mass-producible technology that reliably performs this task, Sparrow Quantum could help construct secure communications infrastructure. This market is expected to grow substantially as governments and corporations seek post-quantum cryptographic resilience.

In conclusion

Sparrow Quantum's €27.5 million Series A investment is a turning point and a vote for photonic quantum technology. Resolving the fundamental deterministic single-photon challenge and providing a scalable, room-temperature substitute for complex cryogenic devices is speeding up commercial quantum application. The Danish spin-off, which has secured full finance for industrial scaling and global reach, is a technology provider and major facilitator in the building of quantum computers and a more secure global communication network. Sparrow Quantum has entered the industrial quantum age.

QTRAIN: Europe’s Deterministic Single-Photon Transceiver

With Breakthrough Miniaturised Transceiver, QTRAIN Consortium Encourages Commercial Quantum Security Worldwide

The ambitious “Quantum Transceiver Based on Deterministic Single-Photon Sources (QTRAIN)” project was founded by major European academic and industrial organisations. QTRAIN, funded by the formidable EUREKA R&D network, aims to produce the first commercial single-photon quantum transceiver. This milestone will move quantum technologies from labs to commercial networks.

With market leaders Sparrow Quantum and Single Quantum, Refined Laser Systems, and Ruhr-Universität Bochum, the alliance combines unique expertise. They want to build and sell this highly integrated device by January 2027.

Redefine Commercial Metrics

The development seeks specific, measurable improvements to minimise commercial adoption barriers. These methods are most appealing since they propose 60% energy savings and 50% physical footprint reduction over lab-scale systems.

The quantum transceiver's massive size reduction makes it suitable for data centres and telecom cabinets, which are already space-constrained. For widespread commercial acceptance, integration must be simple.

The 60% reduction in energy use will also lower network operators' operational costs. High-performance sources and detectors require power-hungry cryostats for cooling. Quantum technology is becoming more affordable and environmentally sustainable due to QTRAIN's co-location and optimisation of components in a single, highly effective cryogenic container.

Final transceiver should be the most advanced photon detecting device for secure quantum communications.

The Co-Integration Breakthrough

The ability to successfully transmit and receive individual packets of light, or single photons, carrying quantum information is at the heart of the quantum communication revolution and crucial for cybersecurity via Quantum Key Distribution (QKD). Current quantum communication systems are complicated, power-hungry, and limited to carefully regulated research facilities since these particles are hard to make and detect.

QTRAIN aims to solve this scaling problem through increased integration. Quantum communication nodes use quantum transceivers to send and receive quantum signals. The single-photon source and detector have traditionally been massive, standalone devices that required complex cryogenic cooling systems.

The ability to house sensitive single-photon detectors and a deterministic source in the same cryostat is QTRAIN's main breakthrough. This innovative co-integration simplifies system design. The device operates at the crucial 1310 nm O-band telecom wavelength. This wavelength provides a standard window for minimal signal loss in optical fibre, ensuring interoperability with global fiber-optic networks.

The Deterministic Security Edge

QTRAIN uses Sparrow Quantum's deterministic single-photon sources, a major technological advantage. This contrasts with commercial Quantum Key Distribution QKD systems, which often use “weak coherent pulse” (WCP) lasers. WCP lasers attenuate laser pulses to reduce photon emission.

Security differs greatly. A single photon is released by deterministic sources. A multi-photon event, in which an eavesdropper (“Eve”) intercepts one of two photons given simultaneously, violates the no-cloning theorem, which underpins QKD's security. Deterministic sources reduce photon waste and potentially improve security by eliminating multi-photon occurrences.

Specialised Knowledge Converges

Successful development of the c requires smooth integration of top partners' highly specialised components:

RUB: This academic partner conducts cutting-edge material science research. RUB offers superior 1310 nm quantum dots. These semiconductor nanocrystal quantum dots are the source component's core and are highly effective and dependable single-photon emitters when stimulated.

Sparrow Quantum: This partner has experience making robust, reliable deterministic single-photon sources that can be used outside of academia.

Single Quantum, a pioneer in photon detection, created and integrated the advanced single-photon detectors and the exceptionally effective cryostat system that would house the transceiver module. Their speciality is superconducting nanowire single-photon detectors (SNSPDs), needed for telecom band high-efficiency detection.

Refined Laser Systems: This partner is expected to deliver extremely accurate, low-noise laser systems to excite quantum dots and assure photon integrity and determinism. The multinational EUREKA R&D network allows these partners from different nations to combine their resources and specialised knowledge, expediting the complex development cycle needed to turn quantum physics into engineering solutions.

Making the Quantum Internet Possible

The importance of an economically practical, compact, and energy-efficient quantum transceiver goes beyond improving QKD systems. It lays the groundwork for the Quantum Internet. In addition to secure connectivity, a fully functional quantum network needs quantum repeaters and memory devices to store and transfer entangled qubits across long distances.

Future networks will use the QTRAIN transceiver as their main input/output port. By showing that complex quantum optical components can be ruggedized and made smaller for commercial usage, the group is setting a modular standard for future quantum networking gear. Small, high-performance transceivers that are easy to mass-produce and install are needed to realise the quantum internet architecture.

If the January 2027 target is satisfied, the QTRAIN quantum transceiver will democratise quantum security and speed up the global quantum network architecture.
