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…
Transition between continuous and discrete spectra in dynamical-decoupling noise spectroscopy
Piotr Szańkowski
Here, we explore the prospects of carrying out the single qubit spectroscopy of environmental noise when the resolution of the frequency filters produced by the dynamical decouplin…
Decoherence-assisted detection of entanglement of two qubit states
Jan Krzywda, Piotr Szańkowski, Jan Chwedeńczuk +1
We show that the decoherence, which in the long run destroys quantum features of a system, can be used to reveal the entanglement in a two-qubit system. To this end, we consider a…
Localization of a magnetic moment using a two-qubit probe
Jan Krzywda, Łukasz Cywiński, Piotr Szańkowski
A nanomagnet precessing in an external magnetic field can be treated as a source of narrow-bandwidth magnetic noise, that leaves characteristic fingerprints in decoherence of a nea…
