TLDR
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.

Success Probability Evaluation of Quantum Circuits based on Probabilistic CNOT-Gates

TL;DR: An abstract probabilistic model of the CNOT gate is defined that takes into consideration error sources and realizability constraints and simulates a three-qubit quantum adder to show the evolution of the probability of realizing correctly the SUM operation depending on the success probability and errors of theCNOT gates.

Compact linear optical scheme for Bell state generation

TL;DR: In this article, the authors reported the most compact scheme for the dual-rail-encoded Bell states out of four single photons, which requires a five-mode interferometer and a single photon detector.

Linear optical deterministic and reconfigurable SWAP gate

TL;DR: In this article, a deterministic SWAP gate for dual-rail-encoded single photon qubits is proposed, which is constructed from waveguide crossings, Mach-Zehnder interferometers and phase shifters.

Quantum Light with Quantum Dots in III-V Photonic Integrated Circuits: Towards Scalable Quantum Computing Architectures

John O'Hara
TL;DR: In this article, the integration of quantum light sources and single-mode beam splitters in the same on-chip device was demonstrated and a new technique to measure very short lifetimes was examined theoretically.
