An All Linear Optical Quantum Memory Based on Quantum Error Correction
Robert M. Gingrich, Pieter Kok, Hwang Lee +2
When photons are sent through a fiber as part of a quantum communication protocol, the error that is most difficult to correct is photon loss. Here, we propose and analyze a two-to…
Entangled Light in Moving Frames
Attila J. Bergou, Robert M. Gingrich, Christoph Adami
We calculate the entanglement between a pair of polarization-entangled photon beams as a function of the reference frame, in a fully relativistic framework. We find the transformat…
Quantum Entanglement of Moving Bodies
Robert M. Gingrich, Christoph Adami
We study the properties of quantum information and quantum entanglement in moving frames. We show that the entanglement between the spins and the momenta of two particles can be in…
Properties of Entanglement Monotones for Three-Qubit Pure States
Robert Gingrich
Various parameterizations for the orbits under local unitary transformations of three-qubit pure states are analyzed. The interconvertibility, symmetry properties, parameter ranges…
Generalized Quantum Search with Parallelism
Robert Gingrich, Colin P. Williams, Nicolas Cerf
We generalize Grover's unstructured quantum search algorithm to enable it to use an arbitrary starting superposition and an arbitrary unitary matrix simultaneously. We derive an ex…
Quantum conditional operator and a criterion for separability
N. J. Cerf, C. Adami, R. M. Gingrich
We analyze the properties of the conditional amplitude operator, the quantum analog of the conditional probability which has been introduced in [quant-ph/9512022]. The spectrum of…
