Measuring distance between quantum states on a quantum computer
A. R. Kuzmak
We propose protocols for determining the distances in Hilbert space between pure and mixed quantum states prepared on a quantum computer. In the case of pure quantum states, the pr…
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…
Implementation of a two-qubit state by an auxiliary qubit on the three-spin system
A. R. Kuzmak
The method for preparation of a two-qubit state on two spins-1/2 that mutually interact through an auxiliary spin is proposed. The essence of the method is that, initially, the thr…
Probing the Lee-Yang zeros of a spin bath by correlation functions and entanglement of two spins
A. R. Kuzmak, V. M. Tkachuk
We study the Lee-Yang zeros of the ferromagnetic Ising bath via the interaction with the two probe spins. Similarly as in paper [Bo-Bo Wei, Ren-Bao Liu, Phys. Rev. Lett. 109, 18570…
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…
Preparation of an arbitrary two-qubit quantum gate on two spins with an anisotropic Heisenberg interaction
A. R. Kuzmak
We consider the two-step method [A. R. Kuzmak and V. M. Tkachuk, Phys. Lett. A 378 (2014) 1469] for preparation of an arbitrary quantum gate on two spins with anisotropic Heisenber…
