Photon Spot Inc. a leading supplier of single photon detector systems has integrated Pressure Wave Systems’ PWG500 into their rack mountable single photon measurement system. Pressure Wave Systems’ compressor drives a Sumitomo RDK-101 cold head that is used to pre-cool a 0.8K sorption stage. Photon spot is running multiple single photon detectors with quantum efficiencies near 90% at various wavelengths. Photon Spot’s turn-key systems can be used for research and development in quantum optics applications including quantum computing, quantum key distribution (qkd), quantum entanglement, quantum memories and many more.
