Extraction of Singlet States from Noninteracting High-Dimensional Spins
Francesco Ciccarello, Mauro Paternostro, Myungshik S. Kim +1
We present a scheme for the extraction of singlet states of two remote particles of arbitrary quantum spin number. The goal is achieved through post-selection of the state of inter…
Nested entangled states for distributed quantum channels
C. Di Franco, M. Paternostro, M. S. Kim
We find a coupling-strength configuration for a linear chain of N spins which gives rise to simultaneous multiple Bell states. We suggest a way such an interesting entanglement pat…
On the distillation and purification of phase-diffused squeezed states
B. Hage, A. Franzen, J. DiGuglielmo +3
Recently it was discovered that non-Gaussian decoherence processes, such as phase-diffusion, can be counteracted by purification and distillation protocols that are solely built on…
Energy Measurements and Preparation of Canonical Phase States of a Nano-Mechanical Resonator
Kurt Jacobs, Andrew N. Jordan, Elinor K. Irish
We show that a continuous quantum non-demolition measurement of the energy of a nanomechanical resonator can be achieved by monitoring the resonator with a quantum point contact vi…
Mapping the Evolution of Optically-Generated Rotational Wavepackets in a Room Temperature Ensemble of D
W. A. Bryan, E. M. L. English, J. McKenna +7
A coherent superposition of rotational states in D has been excited by nonresonant ultrafast (12 femtosecond) intense (2 10 Wcm) 800 nm laser pulses lead…
Probabilistic purification of noisy coherent states
Petr Marek, Radim Filip
A basic feasible probabilistic purification of unknown noisy coherent states, outgoing from different state preparations with unknown mean number of thermal photons, is proposed. T…
