Towards a picosecond transform-limited nitrogen-vacancy based single photon source
Chun-Hsu Su, Andrew D. Greentree, Lloyd C. L. Hollenberg
We analyze a nitrogen-vacancy (NV^-) colour centre based single photon source based on cavity Purcell enhancement of the zero phonon line and suppression of other transitions. Opti…
Error correction optimisation in the presence of X/Z asymmetry
Z. W. E. Evans, A. M. Stephens, J. H. Cole +1
By taking into account the physical nature of quantum errors it is possible to improve the efficiency of quantum error correction. Here we consider an optimisation to conventional…
Asymmetric quantum error correction via code conversion
A. M. Stephens, Z. W. E. Evans, S. J. Devitt +1
In many physical systems it is expected that environmental decoherence will exhibit an asymmetry between dephasing and relaxation that may result in qubits experiencing discrete ph…
The Photonic Module: an on-demand resource for photonic entanglement
Simon J. Devitt, Andrew D. Greentree, Radu Ionicioiu +3
Photonic entanglement has a wide range of applications in quantum computation and communication. Here we introduce a new device: the "photonic module", which allows for the rapid,…
Universal fault tolerant quantum computation on bilinear nearest neighbor arrays
A. M. Stephens, A. G. Fowler, L. C. L. Hollenberg
Assuming an array that consists of two parallel lines of qubits and that permits only nearest neighbor interactions, we construct physical and logical circuitry to enable universal…
Subspace Confinement: How good is your qubit?
Simon J. Devitt, Sonia G. Schirmer, Daniel K. L. Oi +2
The basic operating element of standard quantum computation is the qubit, an isolated two-level system that can be accurately controlled, initialized and measured. However, the maj…
