Journal ArticleDOI
Linear optical quantum computing with photonic qubits
Pieter Kok,William J. Munro,Kae Nemoto,Timothy C. Ralph,Jonathan P. Dowling,Gerard J. Milburn +5 more
TL;DR: In this article, the authors reviewed the original theory and its improvements, and a few examples of experimental two-qubit gates are given, and the use of realistic components, the errors they induce in the computation, and how these errors can be corrected is discussed.
Journal ArticleDOI
Measurement of qubits
Daniel F. V. James,Paul G. Kwiat,Paul G. Kwiat,William J. Munro,William J. Munro,Andrew White,Andrew White +6 more
TL;DR: In this paper, the theory underpinning the measurement of density matrices of a pair of quantum two-level systems is described, and a detailed error analysis is presented, allowing errors in quantities derived from the density matrix, such as the entropy or entanglement of formation.
Journal ArticleDOI
Quantum error correction for beginners.
TL;DR: The basic aspects of quantum error correction and fault-tolerance are examined largely through detailed examples, which are more relevant to experimentalists today and in the near future.
Journal ArticleDOI
Quantum computation with optical coherent states
TL;DR: In this paper, it was shown that quantum computation circuits using coherent states as the logical qubits can be constructed from simple linear networks, conditional photon measurements, and small coherent superposition resource states.
Journal ArticleDOI
Nearly deterministic linear optical controlled-NOT gate.
TL;DR: The key element of this gate is nondemolition detectors that use a weak cross-Kerr nonlinearity effect to conditionally generate a phase shift on a coherent probe if a photon is present in the signal mode.
