Problem
Photonic quantum computers require large numbers of physical qubits and highly precise directional couplers; even nanometer-scale fabrication errors cause logical errors that prevent fault‑tolerant operation, leading to massive manufacturing, cooling, and networking costs.
Solution
Quantum Pulse Ventures offers a patented composited‑pulse technology that improves the accuracy of directional couplers in integrated photonic circuits. By reducing physical error rates, the technology lowers the number of physical qubits needed per fault‑tolerant qubit by up to tenfold, which can accelerate computation speed and cut the projected $1 billion cost of a photonic quantum computer by as much as $900 million. The solution is compatible with existing photonic quantum computer architectures, enabling builders to achieve one to two orders of magnitude improvements in speed, size, or cost without altering their fabrication processes.
Target Audience
Primary customers are developers and manufacturers of large‑scale photonic quantum computers who need higher performance and lower cost scaling for fault‑tolerant systems.
