Quantum 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
متن کاملPreparation of Entangled States and Quantum Teleportation with Atomic Qubits
Quantum information processing has been the subject of intense study for the past ten years. Entanglement is an essential ingredient in order to achieve the exponential speed-up promised by certain quantum algorithms. One system proposed for the implementation of quantum information processing is a string of ions in a linear Paul trap. In this thesis the ability to deterministically prepare and...
متن کاملAtomic Samples in Resonators: Forces, Photons, Feedback
We analyze laser cooling of polarizable particles (classical light scatterers) using continuous dispersive position detection and active feedback with an optical resonator. We derive a simple expression for the cooling force, and show that its magnitude is proportional to the Rayleigh scattering rate into the detector. The velocity dependence of the force is determined exclusively by the freque...
متن کاملAtomic force microscopy of biological samples.
The ability to evaluate structural-functional relationships in real time has allowed scanning probe microscopy (SPM) to assume a prominent role in post genomic biological research. In this mini-review, we highlight the development of imaging and ancillary techniques that have allowed SPM to permeate many key areas of contemporary research. We begin by examining the invention of the scanning tun...
