Few-electron artificial molecules formed by laterally coupled quantum rings
T. Chwiej, B. Szafran
We study the artificial molecular states formed in laterally coupled double semiconductor nanorings by systems containing one, two and three electrons. An interplay of the interrin…
Gated combo nanodevice for sequential operations on single electron spin
S. Bednarek, B. Szafran
An idea for a nanodevice in which an arbitrary sequence of three basic quantum single qubit gates - negation, Hadamard and phase shift - can be performed on a single electron spin.…
Spin rotations induced by electron running on closed trajectories in gated semiconductor nanodevices
S. Bednarek, B. Szafran
A design for a quantum gate performing transformations of a single electron spin is presented. The spin rotations are performed by the electron going around the closed loops in a g…
Magnetic-field asymmetry of electron wave packet transmission in bent channels capacitively coupled to a metal gate
R. Kalina, B. Szafran, S. Bednarek +1
We study the electron wave packet moving through a bent channel. We demonstrate that the packet transmission probability becomes an uneven function of the magnetic field when the e…
