The path to a useful quantum computer

Erik Hosler
Process Exploration for Photonics, PsiQuantum

Quantum computing is the grand challenge of the 21st century and is poised to revolutionizes our daily lives on a nearly unfathomable level. To truly understand the impact, we must first build a universal, fully error corrected machine capable of exploring the application space envisioned by both academic and industry. Numerous pathways have been identified and demonstrated to fabricate single, unique qubits using a myriad of platforms (superconducting, ions, nanoparticles, photons, etc…). However, it is now widely accepted that a truly useful quantum computer will require millions of interconnected, identical qubits to perform fully error corrected, general purpose calculations. To that end, photon-based qubits offer a path to such a general-purpose machine by leveraging the mature silicon photonics high-volume manufacturing ecosystem. Creating quantum devices from silicon photonics components requires patterning innovation to bring leading-edge nanolithography to near macroscopic scale, a unique challenge for an industry where the future relies on progressive device shrink.

Erik R. Hosler leads the Process Exploration for Photonics Department at PsiQuantum, where he is focused on delivering the processes necessary to build the world’s first commercially viable, general-purpose quantum computer.
Prior to joining PsiQuantum, Erik was a member of the Technical Staff and EUV Lead Technologist at GlobalFoundries where he was responsible for driving the industrialization effort of EUV technology for high-volume manufacturing. Erik is an expert on EUV light source technologies and applications, covering laser-produced plasma to free-electron lasers and lithography to metrology, respectively.
Erik received his PhD from the University of California, Berkeley. He has published 29 technical papers, holds seven patents, and is an Associate Editor for JM3.

Stick around after the plenary for a session on the US CHIPS Act and a panel on the nature of the chip shortage.
