Limitations on the maximal level of entanglement of two singlet-triplet qubits in GaAs quantum dots
Igor Bragar, Łukasz Cywiński
We analyze in detail a procedure of entangling of two singlet-triplet (-) qubits operated in a regime when energy associated with the magnetic field gradient, , i…
Interplay of charge noise and coupling to phonons in adiabatic electron transfer between quantum dots
Jan A. Krzywda, Łukasz Cywiński
Long-distance transfer of quantum information in architectures based on quantum dot spin qubits will be necessary for their scalability. One way of achieving it is to simply move t…
Appearance of objectivity for NV centers interacting with dynamically polarized nuclear environment
Damian Kwiatkowski, Łukasz Cywiński, Jarosław K. Korbicz
Quantum-to-classical transition still eludes a full understanding. Out of its multiple aspects, one has recently gained an increased attention - the appearance of objective world o…
Qubit-environment entanglement generation and the spin echo
Katarzyna Roszak, Łukasz Cywiński
We analyze the relationship between qubit-environment entanglement that can be created during the pure dephasing of the qubit and the effectiveness of the spin echo protocol. We fo…
Noise representations of open system dynamics
Piotr Szańkowski, Łukasz Cywiński
We analyze the conditions under which the dynamics of a quantum system open to a given environment can be simulated with an external noisy field that is a surrogate for the environ…
Qubit-environment Negativity versus Fidelity of conditional environmental states for an NV-center spin qubit interacting with a nuclear environment
Małgorzata Strzałka, Damian Kwiatkowski, Łukasz Cywiński +1
We study the evolution of qubit-environment entanglement, quantified using Negativity, for NV-center spin qubits interacting with an environment of C isotope partially polar…
