Nanoscale Mirrored Cavities Amplify Quantum Memories
2015/3/4
The idea of computing systems based on controlling atomic spins just got a boost from new research performed at the Massachusetts Institute of Technology (MIT) and the U.S. Department of Energy's (DOE...
Would one rather store squeezing or entanglement in continuous variable quantum memories?
rather store squeezing entanglement continuous variable
2010/11/5
Given two quantum memories for continuous variables (e.g., the collective pseudo-spin of two atomic ensembles) and the possibility to perform passive optical operations (typically beam-splitters) on t...

Quantum memories based engineered dissipation
2010/11/5
Storing quantum information for long times without disruptions is a major requirement for most quantum information technologies. A very appealing approach is to use self-correcting Hamiltonians, i.e. ...
Global operations for protected quantum memories in atomic spin lattices

Quantum information processed in strongly correlated states of matter can provide built in hardware protection against errors. We may encode information in highly non local degrees of freedom, such as...
Synchronous Quantum Memories with Time-symmetric Pulses
Synchronous Quantum Time-symmetric Pulses
2010/4/9
We propose a dynamical approach to quantum memories using a synchronous oscillator-cavity model, in which the coupling is shaped in time to provide the optimum interface to a symmetric input pulse. Th...
