Analysis of localized Schmidt decomposition modes and of entanglement in atomic and optical quantum systems with continuous variables
A. Yu. Bogdanov, Yu. I. Bogdanov, K. A. Valiev
We investigate the procedure of Schmidt modes extraction in systems with continuous variables. An algorithm based on singular value matrix decomposition is applied to the study of…
Some prospects for ensemble solid-state NMR quantum computers
A. A. Kokin, K. A. Valiev
As an ensemble scheme of solid-state NMR quantum computers the extension of Kane's many-qubits silicon scheme based on the array of 31 P donor atoms are spaced lengthwise of the st…
Problems in realization of large-scale ensemble silicon-based NMR quantum computers
A. A. Kokin, K. A. Valiev
Problems in realization of silicon-based solid-state NMR quantum computer with ensemble addressing to qubits are considered. It is presented the extension of Kane's scheme to ensem…
Novel coherent quantum bit using spatial quantization levels in semiconductor quantum dot
L. Fedichkin, M. Yanchenko, K. A. Valiev
As basic elements of the quantum computer - quantum bits (qubits) we offer semiconductor quantum dots containing one electron each and consisting each of two tunnel-connected parts…
Solid-state NMR quantum computer with individual access to qubits and some its ensemble developments
K. A. Valiev, A. A. Kokin
Here we made an analysis of the principles of a semiconductor NMR quantum computer and its developments. The known variant of an individual-access computer (B. Kane) and alternativ…
