Quantum estimation and remote charge sensing with a hole-spin qubit in silicon
Gaia Forghieri, Andrea Secchi, Andrea Bertoni +2
Hole-spin qubits in semiconductors represent a mature platform for quantum technological applications. Here we consider their use as quantum sensors, and specifically for inferring…
Time-dependent transport in Graphene Mach-Zender Interferometers
Gaia Forghieri, Paolo Bordone, Andrea Bertoni
Graphene nanoribbons provide an ideal platform for electronic interferometry in the Integer Quantum Hall regime. Here, we solve the time-dependent four-component Schroedinger equat…
Band structure of n- and p-doped core-shell nanowires
Andrea Vezzosi, Andrea Bertoni, Guido Goldoni
We investigate the electronic band structure of modulation-doped GaAs/AlGaAs core-shell nanowires for both n- and p-doping. We developed an 8-band Burt-Foreman k.p Hamiltonian appr…
Towards hole-spin qubits in Si pMOSFETs within a planar CMOS foundry technology
L. Bellentani, M. Bina, S. Bonen +6
Hole spins in semiconductor quantum dots represent a viable route for the implementation of electrically controlled qubits. In particular, the qubit implementation based on Si pMOS…
Interacting holes in Si and Ge double quantum dots: from a multiband approach to an effective-spin picture
Andrea Secchi, Laura Bellentani, Andrea Bertoni +1
The states of two electrons in tunnel-coupled semiconductor quantum dots can be effectively described in terms of a two-spin Hamiltonian with an isotropic Heisenberg interaction. A…
Anisotropy of the spin-orbit coupling driven by a magnetic field in InAs nanowires
P. Wójcik, A. Bertoni, G. Goldoni
We use the theory and the envelope function approach to evaluate the Rashba spin-orbit coupling induced in a semiconductor nanowire by a magnetic fiel…
