QC82’s Proprietary Alloy for Room-Temperature Detection Shows State-of-the-Art Avalanche Probability

College Park, MD – April 21st, 2025 – QC82 announced that its proprietary alloy for high-efficiency room-temperature photon detection showed world’s highest measured avalanche probability for telecom wavelength. The importance of this result can be inferred by the fact that the incumbent technology for room temperature detection has shown avalanche probabilities of at most 67% in lab settings, while QC82’s alloy reached 85% with ample room for even higher probabilities. Avalanche probability is an important metric that measures how sensitive an alloy is for detecting photons: higher the probability, higher the sensitivity. By pushing the probability to 90% and higher, QC82 is working on a future where room-temperature detectors will replace cryogenic detectors working at milli-Kelvin to 4 Kelvin temperatures for demanding applications in both quantum communication and computation.
