Nonlocal Nondegenerate Optical Parametric Amplifier Based on Genuine Multipartite Entanglement
We propose a new scheme for realizing nonlocal nondegenerate optical parametric amplifier by means of genuine four-mode entanglement. The nondegenerate optical parametric amplifier is regarded as a unitary transformation from two input fields to two outputs. Two inputs and two outputs are located at the remote stations respectively. Employing off-line four-mode entanglement, homodyne detection,...
متن کاملParametric modulation of an atomic magnetometer.
The authors report on a rubidium atomic magnetometer designed for use in a shielded environment. Operating in the spin-exchange relaxation-free regime, the magnetometer utilizes parametric modulation of the z-magnetic field to suppress noise associated with airflow through the oven and to simultaneously detect x- and y-field components, using a single probe beam, with minimal loss of sensitivit...
متن کاملQuantum communication and memory with entangled atomic ensembles
Quantum information processing, a rapidly developing area of physics, involves operations with quantum states, in which information can be encoded. The number of degrees of freedom available for the encoding grows dramatically, as compared to classical encoding, due to the existence of quantum superpositions. One of the necessary components for quantum information processing is the quantum stat...
متن کاملGeneration of atomic entangled states using linear optics
In this paper, we propose a novel scheme that can generate two-atom maximally entangled states from pure product states and mixed states using linear optics. Because the scheme can generate pure maximally entangled states from mixed states, we denote it as purification-like generation scheme. PACS number(s): 03.67.-a, 03.67.Hk, 03.65.Ud
