This paper presents the optical characteristics of a quantum well doped InP nanocavity.The resonance wavelength of the nanocavity and the optical field intensity is calculated before and after presence of the quantum wells. The resulting huge filed intensity of about 1.2×108 respect to the incident field is the effect of quantum wells placed in vicinity of center of nanocavity.

in this paper we studied the thermal negativity in a two-qubit xx spin ½ chain model and xxx spin1/2 chain model(isotropic heisenberg model)spin-1/2 chain subjected to an external magnetic field inz direction. we calculate analytical relation for the thermal negativity for two qubit xx and xxx spinchain models in the external magnetic field. effects of the magnetic field and temperature on then...

Abstract Three-dimensional (3D) strongly correlated many-body systems, especially their dynamics across quantum phase transitions, are prohibitively difficult to be numerically simulated. We experimentally demonstrate that such complex can efficiently studied in a 3D spinor Bose–Hubbard model simulator, consisting of antiferromagnetic Bose–Einstein condensates confined cubic optical lattices. f...

The power of quantum computers makes it possible to solve difficult problems more efficiently than is possible with traditional computers. Gate-model quantum computers provide an experimentally implementable architecture for quantum circuit computations. Here, we demonstrate an automated method for designing quantum circuits for experimental gate-model quantum computers. We define the Quantum T...
