Impurity and quaternions in nonrelativistic scattering from a quantum memory
Impurity and quaternions nonrelativistic scattering quantum memory
2015/10/16
Models of quantum computing rely on transformations of the states of a quantum memory. We study mathematical aspects of a model proposed by Wu in which the memory state is changed via the scattering o...
Inspired by spin-electric couplings in molecular magnets, we introduce in the Kitaev honeycomb
model a linear modi cation of the Ising interactions due to the presence of quantized cavity elds. This...
Approaches for a quantum memory at telecommunication wavelengths
Approaches quantum memory telecommunication wavelengths
2010/11/8
We report experimental storage and retrieval of weak coherent states of light at telecommunication wavelengths using erbium ions doped into a solid. We use two photon echo based quantum storage protoc...
Broadband waveguide quantum memory for entangled photons
Broadband waveguide quantum memory entangled photons
2010/10/18
The reversible transfer of quantum states of light in and out of matter constitutes an important building block for future applications of quantum communication: it allows synchronizing quantum inform...

2010/3/10
Low loss magnetic surface plasmon polariton (SPP) modes characterized by enhanced electrical field component and subwavelength confinement on the dielectric and negative-index metamaterial interface ...
Quantum memory as a perpetuum mobile of the second kind
Quantum memory perpetuum mobile the second kind
2010/4/7
It is argued that a scalable quantum memory could be used as a perpetuum mobile of the second kind and hence cannot be realized in Nature. The reasoning is based on the assumption that the Landauer's ...
