We report the first simulations of the dynamics of quantum logic operations with a large number of qubits (up to 1000). A nuclear spin chain in which selective excitations of spins is provided by theâ€¦ (More)

We propose a scanning magnetic microscope which has a photoluminescence nanoprobe implanted in the tip of an AFM or STM, or NSOM, and exhibits optically detected magnetic resonance (ODMR). Theâ€¦ (More)

We present a rigorous analysis of the phenomenon of decoherence for general Nâˆ’level systems coupled to reservoirs. The latter are described by free massless bosonic fields. We apply our generalâ€¦ (More)

We present a rigorous analysis of the phenomenon of decoherence for general N-level systems coupled to reservoirs of free massless bosonic fields. We apply our general results to the specific case ofâ€¦ (More)

We analyze the dynamics of N interacting spins (quantum register) collectively coupled to a thermal environment. Each spin experiences the same environment interaction, consisting of an energyâ€¦ (More)

We propose a nuclear-spin quantum computer based on magnetic resonance force microscopy ~MRFM!. It is shown that an MRFM single-electron spin measurement provides three essential requirements forâ€¦ (More)

The perturbation theory is developed based on small parameters which naturally appear in solid state quantum computation. We report the simulations of the dynamics of quantum logic operations with aâ€¦ (More)

We consider the problem of decoherence and relaxation of open bosonic quantum systems from a perspective alternative to the standard master equation or quantum trajectories approaches. Our method isâ€¦ (More)
