The entanglement beam splitter: a quantum-dot spin in a double-sided optical microcavity
C. Y. Hu, W. J. Munro, J. L. O'Brien +1
We propose an entanglement beam splitter (EBS) using a quantum-dot spin in a double-sided optical microcavity. In contrast to the conventional optical beam splitter, the EBS can di…
Giant optical Faraday rotation induced by a single electron spin in a quantum dot: Applications to entangling remote spins via a single photon
C. Y. Hu, A. Young, J. L. O'Brien +1
We propose a quantum non-demolition method - giant Faraday rotation - to detect a single electron spin in a quantum dot inside a microcavity where negatively-charged exciton strong…
Low Cost and Compact Quantum Cryptography
J. L. Duligall, M. S. Godfrey, K. A. Harrison +2
We present the design of a novel free-space quantum cryptography system, complete with purpose-built software, that can operate in daylight conditions. The transmitter and receiver…
Decoherence of geometric phase gates
A. Nazir, T. P. Spiller, W. J. Munro
We consider the effects of certain forms of decoherence applied to both adiabatic and non-adiabatic geometric phase quantum gates. For a single qubit we illustrate path-dependent s…
Maximizing the entanglement of two mixed qubits
W. J. Munro, D. F. V. James, A. G. White +1
Two-qubit states occupy a large and relatively unexplored Hilbert space. Such states can be succinctly characterized by their degree of entanglement and purity. In this letter we i…
