Experimental demonstration of stimulated polarization wave in a chain of nuclear spins
, 2007 A stimulated wave of polarization, which implements a simple mechanism of quantum amplification, is experimentally demonstrated in a chain of four J-coupled nuclear spins, irradiated by a weak radio-frequency transverse field.

Scheme for the generation of an entangled four-photon W-state
, 2002 We present a scheme to produce an entangled four-photon W-state by using linear optical elements. The symmetrical setup of linear optical elements consists of four beam splitters, four polarization beam splitters and four mirrors.

A quantum phase gate implementation for trapped ions in thermal motion
, 2002 We propose a novel scheme to implement a quantum controlled phase gate for trapped ions in thermal motion with one standing wave laser pulse. Instead of applying the rotating wave approximation this scheme makes use of the counter-rotating terms of ...

Quantum teleportation of a single-photon wave packet
, 1998 A quantum teleportation scheme based on the EPR-pair entangled with respect to the ``energy+time'' variables is proposed. Teleportation of the multimode state of a single-photon wave packet is considered.Comment: 6 pages, no ...

Fast geometric gate operation of superconducting charge qubits in circuit QED
, 2011 A scheme for coupling superconducting charge qubits via a one-dimensional superconducting transmission line resonator is proposed. The qubits are working at their optimal points, where they are immune to the charge noise and possess long decoherence time.

Simple procedure for classical signal-procession in cluster-state quantum computation
, 2009 We exhibit a simple procedure to find how classical signals should be processed in cluster-state quantum computation. Using stabilizers characterizing a cluster state, we can easily find a precise classical signal-flow that is required in performing ...

Control of conditional pattern with polarization entanglement
, 2003 Conditional interference patterns can be obtained with twin photons from spontaneous parametric down-conversion and the phase of the pattern can be controlled by the relative transverse position of the signal and idler detectors.

Maximum-likelihood algorithm for quantum tomography [PDF]
, 1999 Optical homodyne tomography is discussed in the context of classical image processing. Analogies between these two fields are traced and used to formulate an iterative numerical algorithm for reconstructing the Wigner function from homodyne statistics ...
