Photon Queue, a quantum technology company building high-efficiency quantum memories for next-generation quantum computing systems, raises $4 million in an oversubscribed seed round led by Playground Global. It plans to use the funding to scale product development and customer deployments.
Photon Queue closes an oversubscribed $4 million seed round led by Palo Alto-based deep-tech venture firm Playground Global. The company plans to use the funding to scale its room-temperature quantum memory systems.
Photon Queue, a University of Illinois Urbana-Champaign (UIUC) spinout developing high-performance quantum memories, joins the Chicago Quantum Exchange as a corporate partner. The startup stores single photons in free-space loops and joins the exchange to advance quantum communication, computing, and metrology.
Photon Queue CEO Nathan Arnold is selected as one of 27 entrepreneurs nationwide for the U.S. Department of Energy’s Lab-Embedded Entrepreneurship Program. He participates in the Chain Reaction Innovations fellowship at Argonne National Laboratory.
