Two-mode Nonlinear Coherent States

Two-mode nonlinear coherent states are introduced in this paper. The pair coherent states and the two-mode Perelomov coherent states are special cases of the two-mode nonlinear coherent states. The exponential form of the two-mode nonlinear coherent states is given. The photon-added or photon-subtracted two-mode nonlinear coherent states are found to be two-mode nonlinear coherent states with d...

One-way quantum computer simulation

In one-way quantum computation (1WQC) model, universal quantum computations are performed using measurements to designated qubits in a highly entangled state. The choices of bases for these measurements as well as the structure of the entanglements specify a quantum algorithm. As scalable and reliable quantum computers have not been implemented yet, quantum computation simulators are the only w...

Quantum Computer Simulation Using CUDA

Quantum computing has captured the attention of many researchers in the past decade. While researchers in the fields of electrical engineering and physics have concentrated on realizing a physical machine that satisfies the criteria of a quantum computing, others in the research community are developing algorithms that can take advantage of such machines. Through exploitation of the inherit sup...

Quantum scissors: Teleportation of single-mode optical states by means of a nonlocal single photon

– We employ the quantum state of a single photon entangled with the vacuum (|1〉A|0〉B −|0〉A|1〉B), generated by a photon incident upon a symmetric beam splitter, to teleport single-mode quantum states of light by means of the Bennett protocol. The teleportation of coherent states results in the truncation of their Fock expansion to the first two terms. We analyze the teleported ensembles by means...
