متن کاملGeneration of arbitrary quantum state in a high-Q cavity
We present a scheme to generate arbitrary superposition of the Fock states in a high-Q cavity . This proposal is based on a sequence of laser pulses, which are tuned appropriately to control transitions on Fock state. It is shown that N laser pulses are needed to generate a pure state with a phonon number limit N . PACS number(s): 03.67.-a, 03.67.Hk. The generation of nonclassical states was ex...
متن کاملImplementation of quantum state manipulation in a dissipative cavity
We discuss a method to perform dissipation-assisted quantum state manipulation in a cavity. We show that atomic spontaneous emission and cavity decay might be exploited to drive many atoms into many-body steady-state entanglement. Our protocol offers a dramatic improvement in fidelity when noise strength increases. Moreover, the dephasing noise is suppressed effectively by showing that high-fid...
متن کاملBichromatic driving of a solid-state cavity quantum electrodynamics system
We theoretically study the bichromatic driving of a solid-state cavity quantum electrodynamics (QED) system as a means of probing cavity dressed state transitions and observing the coherent interaction between the system and the light field. We show that this method can enable the observation of the higher order cavity dressed states, supersplitting and ac-Stark shift in a solid-state system co...
متن کاملThe vacuum state of quantum gravity contains large virtual masses
In the functional integral approach to quantum gravity, the quantum configurations are usually treated to order h̄ through a stationary phase approximation around the saddle point of the action where spacetime is flat. We show that from this point a “level line” in functional space departs, which comprises a family of static non-flat metrics with zero scalar curvature, depending on a continuous ...
