Fault Tolerance in Parity-State Linear Optical Quantum Computing
A. J. F. Hayes, H. L. Haselgrove, Alexei Gilchrist +1
We use a combination of analytical and numerical techniques to calculate the noise threshold and resource requirements for a linear optical quantum computing scheme based on parity…
Universal quantum dynamics from two 2-local Hamiltonians
Charles D. Hill, Henry L. Haselgrove
In this paper, we show that the ability to switch globally between two 2-local Hamiltonians on n qubits is sufficient for achieving universal unitary dynamics on those n qubits. Of…
Fault-tolerant linear optical quantum computing with small-amplitude coherent states
A. P. Lund, T. C. Ralph, H. L. Haselgrove
Quantum computing using two optical coherent states as qubit basis states has been suggested as an interesting alternative to single photon optical quantum computing with lower phy…
Trade-off between the tolerance of located and unlocated errors in nondegenerate quantum error-correcting codes
Henry L. Haselgrove, Peter P. Rohde
In a recent study [Rohde et al., quant-ph/0603130 (2006)] of several quantum error correcting protocols designed for tolerance against qubit loss, it was shown that these protocols…
Noise thresholds for optical cluster-state quantum computation
Christopher M. Dawson, Henry L. Haselgrove, Michael A. Nielsen
In this paper we do a detailed numerical investigation of the fault-tolerant threshold for optical cluster-state quantum computation. Our noise model allows both photon loss and de…
Noise thresholds for optical quantum computers
Christopher M. Dawson, Henry L. Haselgrove, Michael A. Nielsen
In this paper we numerically investigate the fault-tolerant threshold for optical cluster-state quantum computing. We allow both photon loss noise and depolarizing noise (as a gene…
