An Atomtronic Flux Qubit: A ring lattice of Bose-Einstein condensates interrupted by three weak links
D. Aghamalyan, N. T. Nguyen, F. Auksztol +6
We study a physical system consisting of a Bose-Einstein condensate confined to a ring shaped lattice potential interrupted by three weak links. The system is assumed to be driven…
Entanglement convertibility by sweeping through the quantum phases of the alternating bonds chain
Yu-Chin Tzeng, Li Dai, M. -C. Chung +2
We study the entanglement structure and the topological edge states of the ground state of the spin-1/2 XXZ model with bond alternation. We employ parity-density matrix renormaliza…
Information transmission over an amplitude damping channel with an arbitrary degree of memory
A. D'Arrigo, G. Benenti, G. Falci +1
We study the performance of a partially correlated amplitude damping channel acting on two qubits. We derive lower bounds for the single-shot classical capacity by studying two kin…
Coherent manipulation of noise-protected superconducting artificial atoms in the Lambda scheme
P. G. Di Stefano, E. Paladino, T. J. Pope +1
We propose a new protocol for thr manipulation of a three-level artificial atom in Lambda () configuration in the absence of a direct pump coupling. It allows faithful, selectiv…
Generation and Application of Bessel Beams in Electron Microscopy
Vincenzo Grillo, Jérémie Harris, Gian Carlo Gazzadi +6
We report a systematic treatment of the holographic generation of electron Bessel beams, with a view to applications in electron microscopy. We describe in detail the theory underl…
Population transfer in a Lambda system induced by detunings
P. G. Di Stefano, E. Paladino, A. D'Arrigo +1
In this paper we propose a new protocol to achieve coherent population transfer between two states in a three-level atom by using two ac fields. It is based on the physics of Stimu…
