Marty Stevens (Fed)

Staff Scientist

Martin J. Stevens is a member of the Quantum Nanophotonics Group at NIST-Boulder, where he works on single-photon sources, entangled-photon sources, and single-photon detectors. Dr. Stevens was an early pioneer in the use of superconducting nanowire single-photon detectors (SNSPDs) in photon counting and quantum optics applications. He has worked with collaborators around the world implementing these sources and detectors in a variety of experiments, ranging from studies of solid-state and molecular physics to fundamental tests of the quantum nature of light. He developed optical measurement techniques that have led to a better understanding of how SNSPDs operate. Dr. Stevens played a key role in NIST’s 2015 loophole-free test of Bell’s inequality, and helped lead NIST efforts in understanding whether entangled-photon pairs can be used to improve multiphoton microscopy.

Schrödinger held that a local quantum system has some objectively real quantum state and no other (hidden) properties. He therefore took the Einstein-Podolsky
