High-efficiency quantum interrogation measurements via the quantum Zeno effect
P. G. Kwiat, A. G. White, J. R. Mitchell +4
The phenomenon of quantum interrogation allows one to optically detect the presence of an absorbing object, without the measuring light interacting with it. In an application of th…

Grover's search algorithm: An optical approach
P. G. Kwiat, J. R. Mitchell, P. D. D. Schwindt +1
The essential operations of a quantum computer can be accomplished using solely optical elements, with different polarization or spatial modes representing the individual qubits. W…

"Interaction-Free" Imaging
Andrew G. White, Jay R. Mitchell, Olaf Nairz +1
Using the complementary wave- and particle-like natures of photons, it is possible to make ``interaction-free'' measurements where the presence of an object can be determined with…
