Quantum Source

✨ Yesterday we kicked off a new tradition — "A Morning of Inspiration" at Quantum Source. We started our day with a talk by Prof. Barak Dayan who discussed the fundamental scientific principles behind deterministic photon-atom interactions – from the quantum description of single photons, through single-photon nonlinearity, to Quantum Source’s recent PRX Quantum paper, which outlines our photon-atom gates based architecture for large-scale photonic quantum computation. Prof. Avshalom Elitzur followed with a compelling presentation that posed a bold question: Could we be witnessing the beginning of a new revolution in physics — one as profound as the birth of quantum theory itself? Quite possibly, if we accept the idea that quantum processes can evolve not only from past to future, but also from future to past.   This unique perspective, developed by Yakir Aharonov, leads to surprising predictions — even for those well-acquainted with quantum strangeness. In his talk, Prof. Elitzur shared recent developments in this fascinating field. A lively dialogue followed between him and Prof. Dayan, joined by Prof. Eliahu Cohen and Prof. Lev Khaykovich from Bar-Ilan University, demonstrating the power of quantum theory to breathe new life into ancient philosophical paradoxes — and to inspire novel solutions for modern technologies. It was a wonderful chance for us to meet fellow scientists and colleagues from the field, hear updates from old friends, and even debate deep philosophical puzzles – from the Quantum Zeno paradox, to how to house 10 pigeons in 9 boxes without having two in the same box… 🙏 Excited for the next entangled morning...

This week we had the pleasure of hosting the 6th Israel Tech Mission, held in partnership with the PEF Community – a group of post-exit founders, investors, and operators exploring Israel’s innovation, defense, and tech ecosystem. As part of their deep dive into frontier technologies, the group visited Quantum Source to hear from our CEO, Oded Melamed, about the promise and challenges of building a scalable quantum computer using a photonic-based approach. The conversation sparked thoughtful questions around scientific feasibility, commercialization pathways, and why we believe photonics holds the key to making quantum computing practical. We’re grateful for the opportunity to share our work and inspired by the mission’s dedication to engaging with Israel’s next generation of transformative technologies.

We are pleased to unveil the most detailed description of our unique approach to large-scale fault-tolerant quantum computing: Atom-mediated rapid and deterministic generation of photonic graph states, which are the vital "fuel" of any photonic quantum computation. A paper published in PRX Quantum, outlines the architecture of our scheme, which relies on optically interconnected #quantum nodes, each containing a single atom in W-type level structure, coupled to a high-quality micro-resonators. This level scheme allows all the quantum nodes to function as a dynamically configurable single-atom photonic processor, supporting three crucial tasks: single-photon generation, the CZ photon-atom gate, and the SWAP photon-atom gate. The paper outlines how these three operations, and in particular a symmetric version of the CZ gate - the Dual CZ gate - allow versatile generation and expansion of arbitrarily large entangled photonic graph states, as required for error-corrected photonic quantum computation. The feasibility of the scheme is demonstrated by numerical simulations based on the parameters of state-of-the-art chip-based resonators and 87RB atoms at the D1 wavelength of 795nm. By employing atoms as mediators, our #architecture combines the scalability and robustness of photonic qubits alongside the crucial nonlinear interactions provided by atomic qubits. This hybrid approach offers a viable path toward efficient, fault-tolerant large-scale photonic #quantumcomputing. Check out the full paper here: https://lnkd.in/ecDu7_KH

We’re pleased to share that our CEO, Oded Melamed, will be speaking at Q2B Tokyo 2025, the premier global conference for quantum innovation, taking place on May 15–16 at the Grand Hyatt Tokyo.

Big news from Defense Advanced Research Projects Agency (DARPA): After nearly two years of rigorous evaluation, two key #quantumcomputing architectures have been selected for the next phase of validation and co-design in the pursuit of #utility-scale quantum computing—topological qubits and #photonics. At this stage, DARPA has chosen Microsoft and PsiQuantum to advance their respective approaches under the Underexplored Systems for Utility-Scale Quantum Computing (US2QC) program. DARPA's selection marks a critical step toward achieving a fault-tolerant, utility-scale quantum computer—a system capable of solving real-world problems beyond the reach of classical #supercomputers. The recognition of photonic and #topological architectures highlights the industry's shift toward innovative and scalable solutions, paving the way for the future of quantum technology. This announcement is more than just a milestone; it represents a shift in how we approach building a #faulttolerant quantum future. Photonics, once considered unconventional, is now proving indispensable. At Quantum Source, we have long focused on addressing the scalability and efficiency #challenges of quantum computing through a photonic approach. DARPA’s decision reinforces the promise and potential of this path. This is a major step for the #quantum industry—and an exciting time to push the boundaries of photonics in quantum computing.
