Israeli Tower Semiconductor with Xanadu for Photonic Quantum
Israeli Tower Semiconductor news
The Canadian quantum firm Xanadu and semiconductor manufacturer Tower Semiconductor have expanded their photonic quantum hardware relationship. This expanded alliance aims to bring quantum designs from lab to factory. Tower's silicon photonics technology is helping both companies design a fault-tolerant material stack. This strategic cooperation improves integrated photodiodes and low-loss circuits' performance and scalability. The joint venture provides the industrial base for large-scale, commercial quantum computers. This development shows the quantum industry's maturity as mass production approaches.
The two companies had a history of successful “tapeouts” and technological synergy before the announcement. The teams tested and improved Xanadu's sophisticated photonic designs in Tower Semiconductor's process early on to prepare for commercial-scale manufacturing.
A Unique Quantum Hardware Manufacturing Process
This relationship is built on co-engineering a manufacturing flow for Xanadu's proprietary material stack. This stack's architecture compatibility and manufacturing alignment ensure quantum systems' scalability and performance as complexity rises.
By applying these advances to a high-volume foundry, the partners are addressing the quantum industry's largest challenge: moving from lab prototypes to large-scale, manufacturable information processing devices. Christian Weedbrook, Xanadu's founder and CEO, said this relationship has been “instrumental” in developing their technology from early concepts to prototypes and demonstration systems.
Weedbrook said, “We are laying the groundwork for a truly useful quantum computer by fusing Tower's world-class technology and manufacturing expertise with our architectural breakthroughs, fabrication process engineering, and design innovations.”
Tech Focus: Integrated Photodiodes and Ultra-Low Loss Silicon Nitride
Current development efforts focus on optimizing photonic circuit components, which are their building elements. Teams concentrate on:
Silicon nitride (SiN) with ultra-low loss: Essential for quantum signal integrity during circuit transmission. The quantum system needs integrated photodiodes for high-performance measurement and detection.
Xanadu can test its unique designs on a platform that produces large volumes by using standard product processes to make these components. Tower Semiconductor's RF Business Unit vice president and general manager Dr. Ed Preisler calls Xanadu's architecture one of the most scalable.
Preisler added that this agreement verifies Tower's silicon photonics platform's wide spectrum of high-tech applications in data centers, telecommunications, and automotive, beyond quantum computing.
Global Reach of Tower Semiconductor
The connection benefits from Tower Semiconductor's global infrastructure. Tower, a leading analog solution foundry, provides process platforms for industrial, medical, mobile, aerospace, and military applications. Integrated power management, MEMS, SiPho, SiGe, BiCMOS, and CMOS image sensors are among their technologies.
The company has a robust production site network for multi-fab sourcing and expanded capacity for foreign customers:
Israel has one 200mm facility.
Two US 200mm facilities exist.
Japan: 51% TPSCo shareholding authorizes two 200mm and 300mm facilities.
Italy: STMicroelectronics shares Agrate's 300mm factory.
Xanadu's Mission and Software Leadership
After starting in 2016, Xanadu has become a quantum hardware and software leader. The Canadian business aims to create viable, global quantum computers.
In addition to Tower Semiconductor's hardware, Xanadu is a major quantum software player. The company developed PennyLane, a popular open-source application and quantum computing library. Xanadu is a full-stack leader in fault-tolerant quantum computing, focusing on software accessibility and hardware scalability.
Future-focused goals
Tower Semiconductor and Xanadu's alliance is well-positioned to meet the strict manufacturability demands of the next decade as the quantum sector transitions to commercial devices. The press release includes safe harbor statements about the risks and uncertainties of making such forward-looking predictions, but the current trajectory suggests that photonic quantum circuits will eventually be as efficient and reliable as analog semiconductors.
