Recent interest in aspects common to quantum information and condensed matter has
prompted a flurry of activity at the border of these disciplines that were far distant until a few …

The exact quantum dynamics of the reduced density matrix of two coupled spin qubits in a
quantum Heisenberg XY spin star environment in the thermodynamic limit at arbitrarily finite …

The main obstacles to the realization of high-fidelity quantum gates are the control errors
arising from inaccurate manipulation of a quantum system and the decoherence caused by …

Results on heat current, entropy production rate, and entanglement are reported for a
quantum system coupled to two different temperature heat reservoirs. By applying a …

The concept of negativity is adapted in order to explore the quantum and thermal
entanglement of the mixed spin-(1/2, S) Heisenberg dimers in presence of an external …

We study the entanglement generated in the steady state of two interacting qubits coupled to
thermal reservoirs. We show that the amount of steady-state entanglement can be enhanced …

In this work, we study the steady-state entanglement and thermalization of two coupled
qubits embedded in two common baths with different temperatures. The common bath is …

We determine the conditions for the existence of a pair of degenerate parity breaking
separable eigenstates in general arrays of arbitrary spins connected through XYZ couplings …

Nonadiabatic geometric quantum computation protected by dynamical decoupling combines
the robustness of nonadiabatic geometric gates and the decoherence-resilience feature of …

We analyze ground state (GS) factorization in general arrays of spins si with XXZ couplings
immersed in nonuniform fields. It is shown that an exceptionally degenerate set of …
