Measurement-based quantum state transfer and restoring via spin-1/2 chain interacting with environment

E. B. Fel'dman, A. I. Zenchuk

We consider the multi-qubit fixed-excitation state transfer along the spin chain with dipole-dipole interaction subjected to the interaction with environment governed by the Lindbl…

Matrix encoding method in variational algorithm of calculating eigenvalues and generalized eigenvalues

Alexander I. Zenchuk, Junde Wu

We propose a variational method for constructing the eigenvalues and generalized eigenvalues for an arbitrary complex matrix. The quantum part of our algorithm is based…

Teleportation via spin-1/2 chain in solid-state quantum architecture

E. B. Fel'dman, S. I. Doronin, E. I. Kuznetsova +1

We propose the protocol for preparing the maximally entangled Bell state between remote qubits at the ends of the spin-1/2 chain governed by the specially engineered nearest-neighb…

Coherence restoring in communication line via controlled interaction with environment

E. B. Fel'dman, I. D. Lazarev, A. N. Pechen +1

We consider the state-restoring protocol based on the controlled interaction of a linear chain with environment through { incoherent control by} the specially adjusted step-wise ti…

Perfect pure quantum state transfer via state restoring and ancilla measurement

E. B. Fel'dman, J. Wu, A. I. Zenchuk

We propose the protocol for perfect state transfer of an arbitrary pure quantum state along the spin-1/2 chain governed by the Hamiltonian preserving the excitation number in the s…

Arbitrary state creation via controlled measurement

Alexander I. Zenchuk, Wentao Qi, Junde Wu

The initial state creation is a starting point of many quantum algorithms and usually is considered as a separate subroutine not included into the algorithm itself. There are many…
