Preparation and study of the entanglement of the Schrödinger cat state on the ibmq-melbourne quantum computer
A. R. Kuzmak, V. M. Tkachuk
We study the entanglement between a certain qubit and the remaining system in the Schrödinger cat state prepared on the ibmq-melbourne quantum computer. The protocol, which we use…
Detecting entanglement by the mean value of spin on a quantum computer
A. R. Kuzmak, V. M. Tkachuk
We implement a protocol to determine the degree of entanglement between a qubit and the rest of the system on a quantum computer. The protocol is based on results obtained in paper…
Detecting the Lee-Yang zeros of a high-spin system by the evolution of probe spin
A. R. Kuzmak, V. M. Tkachuk
Recently in paper [Peng et al., Phys. Rev. Lett. 114, 010601 (2015)] the experimental observation of the Lee-Yang zeros of an Ising-type spin-1/2 bath, by measuring the coherence o…
The quantum brachistochrone problem for an arbitrary spin in a magnetic field
A. R. Kuzmak, V. M. Tkachuk
We consider quantum brachistochrone evolution for a spin- system on rotational manifolds. Such manifolds are determined by the rotation of the eigenstates of the operator of pro…
