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…
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…
The dynamical-decoupling-based spatiotemporal noise spectroscopy
Jan Krzywda, Piotr Szańkowski, Łukasz Cywiński
Here we demonstrate how the standard, temporal-only, dynamical-decoupling-based noise spectroscopy method can be extended to also encompass the spatial degree of freedom. This spat…
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…
