Quantum Source

🚀 Taking quantum networks out of the lab and into real-world infrastructure. Excited to share that our latest research, developed together with Israel's DDR&D (MAFAT), is now featured in The Quantum Insider. The headline: a single trapped atom can now generate entangled photon pairs on demand, and those pairs hold up perfectly after traveling through more than a kilometer of everyday, unstabilized optical fiber. Some highlights from the work:  🔹 Deterministic generation: A rubidium atom coupled to a microscopic optical cavity fires two entangled photons within tens of nanoseconds of a trigger, replacing the guesswork of probabilistic SPDC sources.  🔹 Built-in resilience: The photons come out in the singlet Bell state—the one entangled state that stays intact no matter how the fiber bends, heats, or flexes. 🔹 Zero compensation needed: No polarization stabilization, no dispersion correction, no active feedback, and still no measurable loss in fidelity over 1km+ of fiber. Prof. Barak Dayan, our Chief Scientist, summed up why this matters: "Once an application requires entangled pairs with both high probability and high fidelity, a deterministic source becomes essential." This kind of robustness is exactly what's needed to move QKD networks, quantum repeaters, and distributed quantum computing out of the lab and into real infrastructure. 📖 Read the full article here: https://lnkd.in/eXAx7eYi

🔬 A milestone for quantum communication, achieved with a single atom. Quantum Source, working with Israel's DDR&D (MAFAT), has demonstrated on-demand generation of entangled photon pairs that survive real-world fiber conditions, with no active stabilization needed. 🔹 A single rubidium atom in a microscopic optical cavity emits two entangled photons on demand: deterministic, unlike probabilistic SPDC sources. 🔹 The photons are generated in the singlet Bell state, uniquely immune to the polarization drift fiber introduces from temperature, bending, and stress. 🔹 Sent through 1km+ of unstabilized fiber, no correction, no calibration, the entanglement arrived with no measurable fidelity loss. "Once an application requires entangled pairs with both high probability and high fidelity... a deterministic source becomes essential," says Prof. Barak Dayan, Chief Scientist at Quantum Source. Why it matters: removing the need for constant calibration simplifies deployment of QKD, quantum repeaters, and distributed quantum computing, another step in translating Israel's quantum science into deployable technology. #QuantumComputing #Photonics #DeepTech #Israel

Scalable, fault-tolerant quantum computing means bridging fundamental physics and robust engineering. At Quantum Source, we're looking for a Director of Embedded Systems to build and lead the team that carries our system through scale-up - recruiting across FPGA, embedded firmware, and real-time software, and owning the roadmap for control, real-time error correction, and HPC orchestration. Who we are looking for: ✅10+ years building complex real-time systems, 5+ years managing multidisciplinary engineering teams. ✅Hands-on FPGA experience and a strong background in embedded firmware and system integration. ✅A technical architect who's scaled distributed compute systems — and organizations. If complex, multidisciplinary challenges drive you and you want to shape large-scale quantum systems, learn more and apply: https://lnkd.in/ebpD6zxG #QuantumComputing #Photonics #Physics #DeepTech #QuantumSource

Today, Quantum Source is introducing a transformative concept in fault-tolerant quantum computing: our compound photon–atom architecture. Rather than building around a single qubit modality, the architecture combines two complementary quantum systems in one fault-tolerant framework: > Photons provide scalable, long-range connectivity. > Atoms provide deterministic entanglement and short-term quantum memory. By letting each modality do what it is naturally best suited for, this blueprint addresses limitations that have challenged both purely photonic and matter-based approaches. The architecture also brings the physical layer and fault-tolerance framework together from the start, including hardware-specific modeling, loss-aware decoding, and a path toward scalable measurement-based quantum computing. This is the first time Quantum Source is presenting its innovative compound architecture: a blueprint for building scalable, fault-tolerant quantum computers from photons and atoms.

The The White House's new quantum initiative sends a clear message: quantum computing is becoming a strategic priority for national competitiveness. As governments around the world increase investments in quantum technologies, the focus is shifting from scientific promise to a much harder challenge: building systems that can scale to the millions of qubits required for utility-scale quantum computing. A key theme from former Israeli Prime Minister Naftali Bennett's recent conversation with The Quantum Insider was that "countries investing in quantum today will be best positioned to benefit when practical quantum computing becomes a reality." At Quantum Source, our team is working to make that future possible through a light-matter Compound architecture designed from day one for scale! #QuantumComputing #FaultTolerantQC #PhotonicQC #QuantumTechnology #QuantumSource #scaleQPUS

What happens if a nation misses the quantum era? That's the question Evan Kubes, President and Co-Founder of The Quantum Insider, posed to former Israeli Prime Minister Naftali Bennett. "It's tantamount to being in a war with horses when your enemies have tanks." In a new interview with The Quantum Insider, Bennett explains why he views quantum computing as a strategic technology, why he believes governments must invest today, and why he chose to join Quantum Source. One of the reasons: the photonic approach. "We front load the problems." The hardest challenges come first. But once solved, the path to scaling becomes dramatically more practical.
