Quantum computing is transitioning from theory to practice, with PsiQuantum Corp., a Bay Area startup, at the forefront, aiming to create the first fault-tolerant quantum computer using silicon photonics. Co-founder Pete Shadbolt emphasizes the field’s momentum as critical technical milestones are being achieved, leading to the prospect of large-scale, commercially viable machines within months. He suggests that the quantum computing sector is currently behind artificial intelligence in terms of practical applications. Shadbolt discussed PsiQuantum’s strategy during an event hosted by theCUBE, highlighting its unique use of silicon photonics—chips that process light—which have surpassed their original telecom applications through collaboration with GlobalFoundries Inc. PsiQuantum’s methodology aims to produce large-scale quantum computers by leveraging established semiconductor manufacturing processes, positioning its innovations within the existing semiconductor ecosystem and targeting applications across chemistry, material science, drug discovery, and other sectors. This integration allows the company to utilize existing manufacturing standards and supply chain infrastructure, circumventing the need for exotic materials.
