The classical bound on image resolution defined by the Rayleigh limit can be beaten by exploiting the properties of quantum mechanical entanglement. If entangled photons are used as signal states, the best possible resolution is instead given by the

Most assessments of network performance make use of metrics that are defined directly in terms of concepts relevant to the transport, network, link and physical layers. These measures of performance provide engineering data useful in characterizing t

The quantum mechanical phenomenon of entanglement can be utilized to beat the the Rayleigh limit, the classical bound on image resolution. This is done by entangling the photons that are used as the signal states. Using entanglement, the best possibl

We show that attenuated N00N states lead to a worse phase estimate than an equally attenuated N separable state unless the transmittance of the medium is very high.

We analyze the phase estimation ability of photonic N00N states propagating in a lossy medium. In such a medium a N00N state of N enangled photons cannot achieve the maximum 1/N phase estimation resolution. In fact, unless the transmittance of the me

The model of quantum computation developed by Kitaev ( 1 ,c4.1) shows that a perfect, error-free, quantum computer can lead to reliable classical outputs, despite the need to apply a necessarily probabilistic measurement. In this paper we extend the

We demonstrate an efficient method of constructing cluster state primitives by exploiting graph state equivalency class properties. We also present a recursion relation for photonic cluster chain length in terms of average resources required.

We demonstrate a method of constructing L-shape cluster states by exploiting equivalence class properties of graph states. The L-shape cluster state is a primitive which can be used to construct cluster states capable of supporting universal quantum
