Aephraim M. Steinberg Physicist

Aephraim Steinberg’s interests lie in fundamental quantum-mechanical phenomena and the control and characterization of the quantum states of systems ranging from laser-cooled atoms to individual photons. His experimental program is two-pronged, using both non-classical two-photon interference and laser-cooled atoms to study: quantum information and computation, decoherence and the quantum-classical boundary, tunneling times, weak measurement and retrodiction in quantum mechanics, and the control and characterization of novel quantum states.
