Colby DeLisle, PhD

⟨quantum|software⟩

I am a senior quantum software engineer at Photonic, Inc., where I work on simulating and programming fault-tolerant quantum architectures.

More generally I am interested in connections between physics and computation. Lately I've been learning more about models of time-reversible classical computation.

Previously, I obtained a PhD in theoretical physics at the University of British Columbia, where I was interested in the quantum information carried by very-long-wavelength (infrared) electromagnetic and gravitational radiation. I also hold a BSc in computer science from the University of Missouri.

Selected work

2026

Computing efficiently in QLDPC codes

Introduces the SHYPS quantum error-correcting codes, and shows that these codes admit an efficient compilation of the full Clifford group using transversal operations.

2024

Distributed quantum computing in silicon

Shares proof-of-concept demonstrations of Photonic's distributed quantum computing architecture.

2021

Soft theorems from boundary terms in the classical point particle currents

Discovers a novel contribution to the electric and gravitational currents of point particles, explaining how those particles broadcast Nature's longest-wavelength signals.
