College Park-based QC82 is developing room-temperature photonic quantum computers for large-scale simulations in chemistry and materials science. Its approach combines proprietary photon-detection technology with low-loss, mass-manufacturable photonic chip designs, aiming to move quantum computing from laboratory systems toward practical industrial infrastructure. The company’s work is supported by a growing portfolio of more than 14 patents and collaboration with University of Virginia co-founders.
IonQ, IncIonQ grew from more than 30 years of academic research and trapped-ion breakthroughs at the University of Maryland and Duke University before Dr. Chris Monroe and Dr. Jungsang Kim founded the company in 2015. Based in College Park, Maryland, it develops commercial quantum computers and helps organizations apply them to difficult computational problems through cloud access and support from quantum scientists.COLLEGE PARK, MD
PhaseshiftPhaseshift is a scientist-founded College Park company built around deep expertise in photonics, quantum science, and advanced optical engineering. It turns metasurface research into practical optical components for organizations developing next-generation photonic and quantum systems.COLLEGE PARK, MD
SEEQCFounded in 2019 as a spinout of superconducting-electronics company Hypres, SEEQC develops quantum-computing processors that integrate quantum circuits and classical control electronics on a single cryogenic chip. Based in Elmsford with facilities in London and Naples, the company also operates a commercial superconducting IC foundry that has fabricated more than 5,000 chip designs. Its System-on-Chip architecture is intended to reduce the cabling, latency, energy use, and complexity that make quantum systems difficult to scale.ELMSFORD, NY
