Almost any quantum spin system with short-range interactions can support toric codes
Maxim Raginsky
Inspired by Kitaev's argument that physical error correction is possible in a system of interacting anyons, we demonstrate that such "self-correction" is fairly common in spin syst…
A fidelity measure for quantum channels
Maxim Raginsky
We propose a fidelity measure for quantum channels in a straightforward analogy to the corresponding mixed-state fidelity of Jozsa. We describe properties of this fidelity measure…
Strictly contractive quantum channels and physically realizable quantum computers
Maxim Raginsky
We study the robustness of quantum computers under the influence of errors modelled by strictly contractive channels. A channel is defined to be strictly contractive if, for an…
Generation and manipulation of squeezed states of light in optical networks for quantum communication and computation
Maxim Raginsky, Prem Kumar
We analyze a fiber-optic component which could find multiple uses in novel information-processing systems utilizing squeezed states of light. Our approach is based on the phenomeno…
