Qubit transformations on Rashba ring with periodic potential
Kregar Ambrož, Ramšak Anton
A spin-qubit transformation protocol is proposed for an electron in a mesoscopic quantum ring with tunable Rashba interaction controlled by the external electric field. The dynamic…
Rashba controlled two-electron spin-charge qubits as building blocks of a quantum computer
Ambroz Kregar, Anton Ramsak
The spin-sensitive charge oscillation, controlled by an external magnetic field, was recently proposed as a mechanism of transformations of qubits, defined as two-electron spin-cha…
Exact spin-orbit qubit manipulation
A. Ramsak, T. Cadez, A. Kregar +1
We consider exactly solvable manipulation of spin-qubits confined in a moving harmonic trap and in the presence of the time dependent Rashba interaction. Non-adiabatic Anandan phas…
Exact unitary transformation for Rashba rings in magnetic and electric fields
A. Kregar, A. Ramsak
An exact solution for single electron states on mezoscopic rings with the Rashba coupling and in the presence of external magnetic and electric fields is derived by means of a unit…
