Efficient Algorithm for Optimal Control of Mixed-State Quantum Systems
Much work has recently been done on control of pure-state quantum systems using the traditional wavefunction formalism [?,?,?]. This work is most important; however many physical systems, such as systems initially in thermal equilibrium or otherwise described by an ensemble of states, or systems where dissipative processes are significant, can not be treated using this approach. Therefore, a de...
متن کاملQuantum noise spectra for periodically driven cavity optomechanics
A growing number of experimental setups in cavity optomechanics exploit periodically driven fields. However, such setups are not amenable to analysis by using simple, yet powerful, closed-form expressions of linearized optomechanics, which have provided so much of our present understanding of experimental optomechanics. In the present paper, we formulate a method to calculate quantum noise spec...
متن کاملUnitary cavity spin squeezing by quantum erasure
Deterministic light-induced spin squeezing in an atomic gas is limited by photon shot noise or, equivalently, by atomic state information escaping with the light field mediating the effective atom-atom interaction. We show theoretically that the performance of cavity spin squeezing [M. H. Schleier-Smith, I. D. Leroux, and V. Vuletić, Phys. Rev. A 81, 021804 (2010)] can be substantially improved...

متن کاملUsing interference for high fidelity quantum state transfer in optomechanics.
We revisit the problem of using a mechanical resonator to perform the transfer of a quantum state between two electromagnetic cavities (e.g., optical and microwave). We show that this system possesses an effective mechanically dark mode which is immune to mechanical dissipation; utilizing this feature allows highly efficient transfer of intracavity states, as well as of itinerant photon states....
