Patented Technology Reduces Qubits Required by Tenfold

Quantum Pulse Ventures (QPV) announced today a universal directional coupler for photonic quantum computers (PQC), providing up to $900M savings on each computer, reducing the cost to build PQCs by an order of magnitude and advancing the availability of practical quantum computers by years. This technology is available today for licensing to builders of quantum computers to accelerate their current plans.

Quantum Pulse Ventures has introduced breakthrough technology for optical quantum computers. Error correcting codes are the only practical way to mitigate physical errors resulting from fabrication errors to achieve fault tolerant qubits. This creates a significant burden on the scale of photonic quantum computers (PQCs). Quantum Pulse Ventures reduces physical errors, and with it the requirement for large error correcting codes, reducing the number of physical qubits required per logical qubit tenfold or accelerating the computer speed by a similar factor, reducing manufacturing, cooling, and networking requirements for PQC builders and potentially saving $900M out of the projected $1B cost per PQC.

“Quantum Pulse lowers hardware requirements, reduces run time and improves robustness against imperfections, bringing scalable, commercial delivery of fault tolerant photonic quantum computers significantly closer to reality,” said Ofer Shapiro, CEO and co-founder of Quantum Pulse Ventures. “By reducing the number of physical qubits required per logical qubit tenfold or accelerating the computer speed by a similar factor, we provide the builders of PQCs the ability to reduce manufacturing, cooling, and networking requirements and potentially save $900M out of the projected $1B cost per PQC. These smaller, cheaper, and faster PQCs will be the cornerstone enabling the quantum computing industry to reach the predicted $1 trillion market impact¹,” continued Shapiro, a serial technology innovator and disruptor, and World Economic Forum Technology Pioneer.

Professor Haim Suchowski of Tel Aviv University and Chief Architect and co-founder of Quantum Pulse Ventures shared, “Photonic operations are susceptible to fabrication error. For classical applications, this amounts to lowering slightly the signal-to-noise ratio, which can be tolerated for many photonic applications. However, for quantum computing and more generally quantum information processing, the issue becomes a show-stopper: if the error is even slightly larger than a well-defined threshold (around 1%), the computation error cannot be corrected – no matter how many more physical units are added to the quantum circuit. Realizing the importance of mitigating the error arising from fabrication imperfections, we decided to import the same physical concept called compositing pulses that enabled the first MRI machines to enter the integrated optical domain. By significantly reducing the error rate, our patented technology significantly reduces the number of qubits required.”

Professor Yaron Oz, former rector of Tel Aviv University, a leading scientist in theoretical physics and co-founder and Chief Scientist of Quantum Pulse Ventures commented, “Error correcting codes are the only practical way to mitigate physical errors resulting from fabrication errors which create a significant burden on the scale of quantum computers. Our technology reduces physical errors and with it, the requirement for large error correcting codes.”

Professor Mordechai (Moti) Segev, renowned scientist in photonics, International Member of the National Academy of Sciences (NAS) of the United States and Member of the Israel Academy of Sciences and Humanities has joined the company’s Board of Directors and shared, “I am a great believer in the optical path to make the promise behind quantum computers come true. Photonics is the way to reach a quantum computer that can actually do something useful, such as global optimization or designing new drugs, simply because photonic quantum computing relies on photonic chips, which leverage the highly advanced fabrication technologies of electronic circuits to create photonic quantum circuitry. Photons are the most robust way to scale up quantum information processing. I have seen many technologies trying to address the gap between theory and practice in quantum computing and was excited by the potential applicability of Quantum Pulse Ventures technology to bridge this gap in what could greatly transform the efficiency, timing, and economics of optical quantum computers.”

This technology was co-developed by Quantum Pulse Ventures and the research team at Tel-Aviv University (TAU) through Ramot, the University's technology transfer company.

Quantum Pulse Ventures, founded in 2021 by leading technologists and scientists, has received exclusive license to patents from TAU that provide the key for scaling photonic quantum computers.
