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…
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…
How to Enhance Dephasing Time in Superconducting Qubits
L. Cywinski, R. M. Lutchyn, C. P. Nave +1
We theoretically investigate the influence of designed pulse sequences in restoring quantum coherence lost due to background noise in superconducting qubits. We consider both 1/f n…
