NISQ-compatible approximate quantum algorithm for unconstrained and constrained discrete optimization
M. R. Perelshtein, A. I. Pakhomchik, Ar. A. Melnikov +7
Quantum algorithms are getting extremely popular due to their potential to significantly outperform classical algorithms. Yet, applying quantum algorithms to optimization problems…
Realization of the Werner-Holevo and Landau-Streater quantum channels for qutrits on quantum computers
A. I. Pakhomchik, I. Feshchenko, A. Glatz +5
We realize Landau-Streater (LS) and Werner-Holevo (WH) quantum channels for qutrits on the IBM quantum computers. These channels correspond to interaction between the qutrit and it…
Extended quantum Maxwell demon acting over macroscopic distances
A. V. Lebedev, G. B. Lesovik, V. M. Vinokur +1
A quantum Maxwell demon is a device that can lower the entropy of a quantum system by providing it with purity. The functionality of such a quantum demon is rooted in a quantum mec…
Quantum H-theorem and irreversibility in quantum mechanics
G. B. Lesovik, I. A. Sadovskyy, A. V. Lebedev +2
We investigate temporal evolution of von Neumann's entropy in exemplary quantum mechanical systems and show that it grows in systems evolving with incrementally increasing decohere…
