Observation of spin-1 tunneling on a quantum computer
Kh. P. Gnatenko, V. M. Tkachuk
Spin-1 tunneling and splitting of energy levels as a result of tunneling are observed explicitly on IBM's quantum computer, ibmq-bogota. The spin-1 is realized with two spins-1/2.…
Entanglement of graph states of spin system with Ising interaction and its quantifying on IBM's quantum computer
Kh. P. Gnatenko, V. M. Tkachuk
We consider graph states generated by operator of evolution with Ising Hamiltonian. The geometric measure of entanglement of a spin with other spins in the graph state is obtained…
Minimal momentum estimation in noncommutative phase space of canonical type with preserved rotational and time reversal symmetries
Kh. P. Gnatenko
Noncommutative algebra which is rotationally invariant, time reversal invariant and equivalent to noncommutative algebra of canonical type is considered. Perihelion shift of orbit…
Features of description of composite system's motion in twist-deformed space-time
Kh. P. Gnatenko
Composite system made of particles is considered in twist-deformed space-time. It is shown that in the space the motion of the center-of-mass of the system depends on the relat…
Harmonic oscillator chain in noncommutative phase space with rotational symmetry
Kh. P. Gnatenko
We consider a quantum space with rotationally invariant noncommutative algebra of coordinates and momenta. The algebra contains tensors of noncommutativity constructed involving ad…
Parameters of noncommutativity in Lie-algebraic noncommutative space
Kh. P. Gnatenko
We find condition on the parameters of noncommutativity on which a list of important results can be obtained in a space with Lie-algebraic noncommutativity. Namely, we show that th…
