Integrability of open boundary driven quantum circuits
Chiara Paletta, Tomaž Prosen
Izvirni znanstveni članek
Oznake: kvantna fizika;kvantna integrabilnost;kvantna vezja;quantum physics;quantum integrability;quantum circuits;
In this paper, we address the problem of Yang-Baxter integrability of doubled quantum circuit of qubits (spins 1/2) with open boundary conditions where the two circuit replicas are only coupled at the left or right boundary. We investigate the cases where the bulk is given by elementary six vertex u ...

Oznake: kvantna vezja;integrabilnost;spinski transport;quantum circuits;integrability;spin transport;
We revisit the integrability of quantum circuits constructed from two-qubit unitary gates U that satisfy the Yang–Baxter equation. A brickwork arrangement of U typically corresponds to an integrable Trotterization of some Hamiltonian dynamics. Here, we consider more general circuit geometries which ...

We consider spin chain models with local Hamiltonians that display weak ergodicity breaking. In these models, the majority of the eigenstates are thermal, but there is a distinguished subspace of the Hilbert space in which ergodicity is broken. We achieve such a weak breaking by embedding selected i ...
