Heralded Two-Photon Entanglement from Probabilistic Quantum Logic Operations on Multiple Parametric Down-Conversion Sources
T. B. Pittman, M. M. Donegan, M. J. Fitch +5
An ideal controlled-NOT gate followed by projective measurements can be used to identify specific Bell states of its two input qubits. When the input qubits are each members of ind…
Experimental Controlled-NOT Logic Gate for Single Photons in the Coincidence Basis
T. B. Pittman, M. J. Fitch, B. C Jacobs +1
We report a proof-of-principle demonstration of a probabilistic controlled-NOT gate for single photons. Single-photon control and target qubits were mixed with a single ancilla pho…
High-fidelity quantum logic operations using linear optical elements
J. D. Franson, M. M. Donegan, M. J. Fitch +2
Knill, Laflamme, and Milburn [Nature 409, 46 (2001)] have shown that quantum logic operations can be performed using linear optical elements and additional ancilla photons. Their a…
Dispersion cancellation and non-classical noise reduction for large photon-number states
M. J. Fitch, J. D. Franson
Nonlocal dispersion cancellation is generalized to frequency-entangled states with large photon number N. We show that the same entangled states can simultaneously exhibit a factor…
