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…
Relationship between subjecting the qubit to dynamical decoupling and to a sequence of projective measurements
Fattah Sakuldee, Łukasz Cywiński
We consider a qubit coupled to another system (its environment), and discuss the relationship between the effects of subjecting the qubit to either a dynamical decoupling sequence…
Spectroscopy of classical environmental noise with a qubit subjected to projective measurements
Fattah Sakuldee, Łukasz Cywiński
We show theoretically how a correlation of multiple measurements on a qubit undergoing pure dephasing can be expressed as environmental noise filtering. The measurement of such cor…
