Quantum Pulse Ventures

In MRI, composite pulses are used to make physical operations more robust by arranging multiple pulses so that their errors interfere destructively. Prof. Haim Suchowski, our Chief Architect and Co-Founder, saw how that same principle could be brought into integrated #photonics.

Quantum computing promises to solve problems that are critical to mankind, from new materials to new drugs and challenges that were once considered unsolvable. But the biggest challenge is scale. With today’s technology, building a useful quantum computer may require at least a million physical qubits. That is a tremendous engineering challenge. At Quantum Pulse Ventures, our vision is to help make optical quantum computers faster and more affordable by reducing the physical complexity required to scale. Our technology is built around a change in the directional coupler — the optical junction where two qubits can interact in a photonic circuit. Think of it as the transistor of optical computing. By improving this critical component, Quantum Pulse Ventures technology can integrate with photonic quantum computers and help make them 10× smaller, 10× less expensive, or in some cases 10× faster than other technologies. Because at this scale, even a one-nanometer manufacturing inaccuracy can introduce errors that compound throughout the calculation process. Scaling quantum computing starts at the component level.

The coupler allowed light to jump from one waveguide to another, similar to a transistor in a traditional CMOS circuit. The wave guides themselves are “very, very small; they are less than one micrometer in size, and the distance between them has to be accurate in a sub-nanometer level for this operation to be accurate.” - Ofer Shapiro, Co-founder and CEO of Quantum Pulse Ventures At this scale, precision “becomes a huge manufacturing issue, and that's why many of those solutions are just at the cusp of functionality.” #Optica #quantum

Quantum computing has a scaling problem. Useful optical quantum computers may require massive numbers of physical qubits, making cost and complexity major barriers. At Quantum Pulse Ventures, we address this at the directional coupler — the “transistor” of optical computing. Our technology is universal, patent-protected, and available for licensing.

“We are entering a period where light is no longer a communication medium, but rather part of the computational fabric.” — @ofershapiro Shapiro, CEO and Co-Founder, Quantum Pulse Ventures For decades, photonics was primarily about transmitting information from one point to another. That is changing. As light becomes part of the computation itself, the requirements for photonic systems change with it. Fidelity, robustness, precision, and fabrication tolerance are no longer secondary considerations — they become central to performance and scalability. This is the shift driving Quantum Pulse 2.0. We believe the next generation of quantum computing, quantum routing, and optical processing will be defined not only by what light can carry, but by what light can compute.

Quantum computing will not scale unless we reduce error at the physical level. In photonic quantum computers, every device matters. Every qubit, every gate, every splitting ratio, every phase error can affect the performance of the full system. As Prof. Mordechai “Moti” Segev explains, the lower the physical error, the more we can reduce the number of devices needed for error correction — and the shorter the computation time can become. That is where Quantum Pulse Ventures comes in. Our technology addresses errors at the level of the individual photonic device. It has been proven in the lab to reduce error in both the splitting ratio between channels and the phase. This is why we see Quantum Pulse as an enabling technology for photonic quantum computing. Because without reducing physical error, building a full-scale quantum computer becomes extremely difficult.

In photonic quantum computing, reducing physical error is not a detail. It is a requirement for scalability. Improving splitting-ratio accuracy and phase control means improving the fidelity of the photonic building blocks that quantum systems depend on. That is exactly the challenge Quantum Pulse Ventures is built to address. Read more at: quantumpulse.ventures/ #QuantumComputing #Photonics #IntegratedPhotonics #QuantumTechnology
