Rydberg Technologies Unveils Rydberg Photonics In Berlin
Rydberg Photonics Launches in Berlin, Combining German Engineering and American Systems to Scale Quantum Technology
The well-known American quantum sensing business Rydberg Technologies Inc. established Rydberg Photonics GmbH in Berlin. The industrialisation of quantum technology depends on this. This strategic location is a powerful combination of U.S. quantum systems expertise and world-class German photonics engineering, with the aim of producing the next generation of micro-integrated components that are crucial for expanding the global quantum ecosystem.
Rydberg Photonics is a new company that is a dynamic spin-off from the prestigious Ferdinand-Braun-Institut (FBH), a well-known brand in high-frequency and high-power electronics and photonics. Providing compact, dependable, and high-performing micro-integrated photonic engines that will serve as the main power source and control system for quantum devices worldwide is the clear and ambitious objective of this new Berlin-based company.
Quantum-Scale Continental Connectivity: Strategic Justifications Rydberg Photonics' launch attempts to bridge laboratory-proven quantum principles and field-ready technology. It is regarded as a master class in international strategic cooperation. The core source of synergy is the combination of the distinctive features of the parent company and the organisation from which the spin-off is generated.
Rydberg Technologies Inc. offers its vast experience in developing cutting-edge quantum systems, particularly in the area of quantum sensing, which demands unparalleled accuracy and stability. Conversely, FBH provides over a decade of innovative research in micro-integrated photonics, as well as its unique expertise in hybrid micro-integration technology.
The significance of this combination was emphasised by Dr. David A. Anderson, CEO of Rydberg Technologies and co-founder of Rydberg Photonics. "This partnership is a strategic fusion that will significantly speed up global deployment, not just an expansion," he stated. He continued by saying that by fusing German technical expertise in photonics with American system development, the businesses are "positioned to deliver field-ready quantum and advanced photonic solutions at scale." He emphasised that the advancement of quantum discoveries from the lab to the international industrial, scientific, and commercial sectors depends on this partnership. Rydberg Technologies and Rydberg Photonics will collaborate in the US and European markets as key partners.
Breaking the Bottleneck of Quantum
The quantum industry has long recognised a major bottleneck: the most powerful quantum devices often rely on massive, power-hungry, vibration-sensitive optical equipment. Rydberg Photonics aims to get around this restriction by leveraging FBH's proven ability to condense complex optical components onto compact, robust modules.
This transition from benchtop complexity to micro-integrated, turnkey engines will enable the eventual deployment of clocks, sensors, and Quantum Communications in real-world environments. Manufacturing floors, data centres, aeroplanes, and spacecraft are examples of environments that are challenging to operate. The micro-integrated photonic engines are self-contained, easy to use, and sufficiently stable to perform well even under the most demanding conditions.
Technology's Edge: Accurate Miniaturisation
After nearly a decade of pioneering research at the FBH, Rydberg Photonics is concentrating on performance-preserving miniaturisation, a notoriously challenging subject in high-precision photonics. The main technological advantage of FBH is its unique hybrid micro-integration technique. This specialised technique allows for the exact and reliable assembly of a wide range of components, such as semiconductor lasers, optical fibres, and micro-optics, into a single, small, and robust platform.
The level of robustness achieved by this integration is inevitable for quantum systems. For example, an extremely stable laser source is needed in quantum computing to cool and manipulate individual atoms or ions. Any drift or instability in the photonics is strongly associated with errors in the quantum calculation. By offering components built for stability from the ground up, Rydberg Photonics is directly addressing one of the most persistent obstacles to the adoption of quantum technology.
Crucial Components of the Quantum Revolution
Rather than being auxiliary components, Rydberg Photonics' initial product offerings are the main workhorses of the modern quantum environment. Based on over a decade of FBH research, the company's first products will include:
Compact and Turnkey Optical Frequency References: These components act as the extraordinarily steady heartbeats of a quantum system. An optical frequency reference provides a very stable and precisely known frequency signal. This stability is crucial because reference atomic transitions determine how accurate atomic clocks are. Quantum clocks are portable for next-generation GPS-free navigation and extremely secure communication networks due to their reduced references.
Hybrid Integrated High-Power, Narrow-Linewidth Lasers Most cutting-edge quantum technologies, like the neutral atom and Rydberg-atom-based trapped-ion quantum computers, require highly specialised lasers. To properly measure atom energy changes, a narrow-linewidth laser must output pure-color light. Scientists cannot read, write, or store qubits without this precision. Rydberg Photonics is enabling the deployment of these powerful and complicated lasers outside of climate-controlled labs by substantially lowering their size and enhancing their mechanical and thermal stability through hybrid integration.
These specialised components are necessary for many different quantum applications:
Quantum sensors' sensitivity to gravity, electric, and magnetic forces could revolutionise medical diagnosis and subsurface surveys.
Quantum clocks provide exact time for portable atomic clocks for global synchronisation, military security, and financial trading.
Continuous light sources from Quantum Communications ensure future data security for Quantum Key Distribution (QKD) systems.
Control layers for neutral-atom and trapped-ion systems in quantum computing, where laser accuracy determines qubit fidelity.
The establishment of Rydberg Photonics in Berlin is a clear sign of the intensifying battle for the global commercialisation of quantum technology. Germany's strong industrial base and wealth of technological expertise, particularly in the areas of optics and photonics, make it the perfect place for this kind of manufacturing venture.
It is anticipated that the combination of U.S. system-level experience with German component-level accuracy will solve the industry's main integration issues. Rydberg Photonics seeks to lower supply chain risk for global quantum producers and help the quantum technology ecosystem move from research to commercial size and ubiquity by focused on these fundamental factors.
Since its inception, the global endeavour to turn quantum physics into deployable technology has accelerated in Europe.
Marcar a passagem do tempo em um mundo de relógios de tique-taque e pêndulos balançando é um simples caso de contar os segundos entre "então" e "agora".Na escala quântica de elétrons zumbindo, no entanto, "então" nem sempre pode ser antecipado. Pior ainda, "agora" muitas vezes borra em uma névoa de incerteza. Um cronômetro simplesmente não vai cortá-lo para alguns cenários.Uma solução em potencial poderia ser encontrada na própria forma da neblina quântica em si, de acordo com pesquisadores da Universidade de Uppsala, na Suécia.Esta pesquisa foi publicada na Physical Review Research.Entendendo o estado rydbergSeus experimentos sobre a natureza ondulada de algo chamado estado rydberg revelaram uma nova maneira de medir o tempo que não requer um ponto de partida preciso.Os átomos de Rydberg são os balões superinflados do reino das partículas. Inchados com lasers em vez de ar, esses átomos contêm elétrons em estados de altíssima energia, orbitando longe do núcleo.Claro, nem toda bomba de laser precisa soprar um átomo até proporções cartunescas. Na verdade, os lasers são rotineiramente usados para fazer cócegas em elétrons em estados de maior energia para uma variedade de usos.a) Um pulso XUV ultracurto, mostrado em roxo, com energia central próxima ao limiar de ionização, é usado para criar uma superposição coerente dos estados de Rydberg. Posteriormente, um pulso laser NIR ultracurto, mostrado em vermelho, ioniza o átomo animado, resultando em fotoeletrões com uma energia cinética de família. b) Simulação de batidas quânticas originárias exclusivamente da interferência entre os níveis Ele1s13p1Pe. Ele 1s14p1P com separação de energia de ΔE=11Mev. c) Após a excitação XUV, o WP consiste em todos os níveis de energia entren=10e ∞.Em algumas aplicações, um segundo laser pode ser usado para monitorar as mudanças na posição do elétron, incluindo a passagem do tempo. Estas técnicas de "bomba-sonda" podem ser usadas para medir a velocidade de certos eletrônicos ultrarrápido, por exemplo.Induzir átomos nos estados de Rydberg é um truque útil para os engenheiros, especialmente quando se trata de projetar novos componentes para computadores quânticos. Desnecessário dizer, os físicos acumularam uma quantidade significativa de informações sobre a forma como os elétrons se movem quando cutucados em um estado de Rydberg.O livro de regras matemáticas por trás deste jogo selvagem da roleta eletrônica rydberg é referido como um pacote de ondas Rydberg.Assim como ondas reais em um lago, ter mais de um pacote de ondas rydberg ondulando em um espaço cria interferência, resultando em padrões únicos de ondulações. Jogue pacotes de ondas rydberg suficientes no mesmo lago atômico, e esses padrões únicos representarão cada um o tempo distinto que leva para os pacotes de ondas evoluírem de acordo uns com os outros.Foram essas "impressões digitais" do tempo que os físicos por trás deste último conjunto de experimentos se propus a testar, mostrando que eram consistentes e confiáveis o suficiente para servir como uma forma de timestamping quântico.A pesquisaSua pesquisa envolveu medir os resultados de átomos de hélio excitados a laser e combinar suas descobertas com previsões teóricas para mostrar como seus resultados de assinatura poderiam permanecer por um período de tempo."Se você está usando um contador, você tem que definir zero. Você começa a contar em algum momento. O benefício disso é que você não precisa começar o relógio – basta olhar para a estrutura de interferência e dizer 'ok, foram 4 nanossegundos'." explicou a física Marta Berholts, da Universidade de Uppsala, na Suécia, que liderou a equipe, ao New Scientist.Um guia de pacotes de ondas rydberg em evolução poderia ser usado em combinação com outras formas de espectroscopia de sonda de bomba que medem eventos em uma escala minúscula, quando agora e depois são menos claros, ou simplesmente inconvenientes demais para medir.É importante ressaltar que nenhuma das impressões digitais requer um momento e agora para servir como ponto de partida e parada para o tempo. Seria como medir a corrida de um velocista desconhecido contra vários competidores correndo em velocidades definidas.Ao procurar a assinatura de estados de Rydberg interferindo em meio a uma amostra de átomos de sonda de bomba, os técnicos puderam observar um estamp de tempo para eventos tão fugazes quanto apenas 1,7 trilhões de segundo.Futuros experimentos de relógio quântico poderiam substituir o hélio por outros átomos, ou mesmo usar pulso laser de diferentes energias, para ampliar o guia de fusos de tempo para se adequar a uma gama mais ampla de condições.Este artigo é traduzido e adaptado do original em ScienceAlert.
Spectre de l’hydrogène
La longueur d’onde des raies émises par l’atome d’hydrogène est prédite par une formule appelée formule de Rydberg :
Cette formule généralise une formule empirique établie par Johann Balmer en 18885 à partir des raies de l’hydrogène dans le domaine visible. Le fondement théorique de cette formule ne fut découvert que plus tard, grâce aux travaux de Niels Bohr. Il démontra que les raies spectrales d’un atome correspondaient à des sauts quantiques entre les différents états d’énergie possible de ses électrons. Ces états d’énergie sont quantifiés et l’équation de Schrödinger permet de les déterminer. Chacun de ces sauts se traduit par l’émission d’un photon dont la longueur d’onde est inversement proportionnelle au différentiel d’énergie :
Dans le cas d’un atome d’hydrogène, on peut simplifier l’équation de Schrödinger en l’appliquant à un électron évoluant dans un potentiel coulombien. Il est possible alors possible de la résoudre analytiquement. On montre que l’écart entre les différents niveaux d’énergie possibles correspondent bien aux valeurs prédites par la formule de Rydberg. En astronomie, on a donné un nom aux différentes séries de raies spectrales de l’atome d’hydrogène :
La formule de Rydberg s’applique aussi aux atomes hydrogénoïdes. Les atomes hydrogénoïdes sont des cations dépouillés de tous leurs électrons sauf 1 (Li2+, Be3+...). Dans ce cas :
Z étant le numéro atomique de l’atome considéré, M sa masse atomique et me la masse de l’électron.
Lorsque les atomes possèdent plus d’un électron dans leur bande de valence, la formule de Rydberg ne s’applique plus. Il faut tenir compte d’un phénomène appelé couplage spin-orbite (voir le post à ce sujet).

Vem är Gullveig som tre gånger blev bränd?
Vem är Gullveig som tre gånger blev bränd i ett dåd som blev starten för kriget mellan Asar och Vaner? Viktor Rydberg skingrar förvirringen på ett sätt som går tvärt emot många andra forskares teorier.
Asar och Vaner är två gudasläkter som i tidernas begynnelse utkämpade ett fruktansvärt krig. I Valans spådom berättas det om hur kriget började.
Det fältslag minns hon först i världen, när de med spjuten spetsade Gullveig och i den Höges sal henne brände. Tre gånger brände de den tre gånger borna, ofta, ej sällan, dock ännu hon lever.
Valans spådom, 21

Scef - Den förste kungen
Scef - Den förste kungen Vi läser Viktor Rydberg och hittar en berättelse från bronsåldern. Den handlar om den förste kungen, Scef.
Jag har just förvärvat ett exemplar av Viktor Rydbergs bok Undersökningar i Germanisk Mythologie. Det är ett gigantiskt verk, där Rydberg verkligen försöker vända ut och in på hela den germanska mytologin, ända från den poetiska eddan fram till berättelserna om de olika kungasläktena. Syftet med dessa släktsagor var att förklara hur vikingatidens, och senare medeltidens kungar var besläktade med…
