In this article, the operation and tolerances of a quantum controlled-NOT gate for photonic qubits are described and a two-photon source is used for its demonstration.
Abstract
We describe the operation and tolerances of a nondeterministic, coincidence basis, quantum controlled-NOT gate for photonic qubits. It is constructed solely from linear optical elements and requires only a two-photon source for its demonstration. Its success probability is 1/9.

Silica-on-silicon waveguide circuits and superconducting detectors for integrated quantum information processing

TL;DR: In this article, a low-loss source of single photons and a low loss silica-on-silicon waveguide architecture were developed along with a statistical test to verify that this multi-photon circuit behaves as expected.

Experimental noiseless linear amplification using weak measurements

TL;DR: In this article, a quantum logic gate is used to weakly couple a small single-optical-mode quantum state (the signal) to an ancilla photon (the meter).

Quantum teleportation and entanglement swapping with linear optics logic gates

TL;DR: In this article, the use of a linear optics phase gate for distinguishing all four Bell states simultaneously in a quantum teleportation and entanglement swapping protocol is reported, which yields average state fidelities of about 0.83 and 0.77, respectively.

Beating the classical limits of information transmission using a quantum decoder

TL;DR: This work experimentally demonstrate quantum enhanced communication over an amplitude damping noisy channel with only two uses of the channel per bit and a single entangling gate at the decoder, and shows how this methodology can be extended to larger systems by simulating the transmission of a single bit with up to eight uses of a channel and a two-bit message with three uses ofthe channel.

Robust Interferometric Sensing Using Two-Photon Interference

TL;DR: In this article, the authors show that nonclassical interference can provide a path towards robust interferometric sensing, allowing for increased metrological precision in the presence of phase noise, which is known to be less sensitive to phase fluctuations.
