Research interests

Experimental laser cooling and quantum optics

Professor Steinberg works at the forefront of experimental quantum optics and quantum information.

He is internationally known for his seminal work, both experimental and theoretical, on "superluminal" effects in tunnelling and optical propagation, as well as for his ongoing projects using ultracold atoms and entangled photons to study the subtle mysteries of quantum mechanics along with their potential applications to information processing. Dr. Steinberg has rapidly become a world leader in two major areas of quantum physics.
