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…

Adiabatic electron charge transfer between two quantum dots in presence of 1/f noise

Jan Krzywda, Łukasz Cywiński

Controlled adiabatic transfer of a single electron through a chain of quantum dots has been recently achieved in GaAs and Si/SiGe based quantum dots, opening prospects for turning…

Influence of nuclear spin polarization on spin echo signal of NV center qubit

Damian Kwiatkowski, Piotr Szańkowski, Łukasz Cywiński

We consider the spin echo dynamics of a nitrogen-vacancy center qubit based the ground state spin manifold, caused by a dynamically polarized nuclear environment. We sh…

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…
