Alignment of the amplitudes of stored states for solving the associative memory problem using quantum annealing
Vladimir E. Zobov, Ivan S. Pichkovskiy
The solution of combinatorial optimization problems by means of quantum annealing is based on the preparation of an equally superposition state. Such superposition is crucial to th…
Clustering into three groups on a quantum processor of five spins S = 1, controlled by pulses of resonant RF fields
I. S. Pichkovskiy, V. E. Zobov
We consider a quantum processor based on five qutrits represented by spins S=1, which is driven by radio fre-quency (RF) pulses selective in transitions between adjacent levels. Nu…
Clustering by quantum annealing on three-level quantum elements qutrits
V. E. Zobov, I. S. Pichkovskiy
Clustering is grouping of data by the proximity of some properties. We report on the possibility of increasing the efficiency of clustering of points in a plane using artificial qu…
The stabilization of width of multiple-quantum NMR spectrum induced by decoherence
A. A. Lundin, V. E. Zobov
As opposed to traditional methods of multiple-quantum NMR spectroscopy authors of the article [G.A. Alvarez, D. Suter, Phys. Rev. A 84, 012320 (2011)] generated the effective doubl…
Quantum discord in the central spin model
V. E. Zobov
The quantum properties of dynamic correlations in a system of an electron spin surrounded by nuclear spins under the conditions of free induction decay (FID) and spin echo have bee…
Quantum and classical correlations in the solid-state NMR free induction decay
V. E. Zobov, A. A. Lundin
The free-induction decay (FID) of the transverse magnetization in a dipolar-coupled rigid lattice is a fundamental problem in magnetic resonance and in the theory of many-body syst…
On the time-optimal implementation of quantum Fourier transform for qudits represented by quadrupole nucleus
V. P. Shauro, V. E. Zobov
We consider the problem of time-optimal realization of the quantum Fourier transform gate for a single qudit with number of levels d from 3 to 8. As a qudit the quadrupole nucleus…
The quantum dynamics of two coupled large spins
V. E. Zobov
We calculate the time evolution of mean spin components and the squared I-concurrence of two coupled large spins S. As the initial conditions we take two cases: spin coherent state…
Quantum and classical correlations in high temperature dynamics of two coupled large spins
V. E. Zobov
We study dynamical correlations of two coupled large spins depending on the time and on the spin quantum numbers. In the high-temperature approximation, we obtain analytical expres…
