Superconductor-semiconductor hybrid capacitance with a nonlinear charge-voltage profile
Joachim Lauwens, Lars Kerkhofs, Arnau Sala +1
Electronic devices that work in the quantum regime often employ hybrid nanostructures to bring about a nonlinear behaviour. The nonlinearity that these can provide has proven to be…
Line Shapes of Electric Dipole Spin Resonance in Pauli Spin Blockade
Arnau Sala, Jeroen Danon
Electric dipole spin resonance (EDSR) is a commonly used tool for manipulation and spectroscopy of quantum-dot-based spin qubits. When an EDSR experiment is embedded in a transport…
Highly tunable exchange-only singlet-only qubit in a GaAs triple quantum dot
Arnau Sala, Jørgen Holme Qvist, Jeroen Danon
We propose an implementation of a singlet-only spin qubit in a GaAs-based triple quantum dot with a (1,4,1) charge occupation. In the central multi-electron dot, the interplay betw…
Leakage and dephasing in Si-based exchange-only spin qubits
Arnau Sala, Jeroen Danon
Exchange-only spin qubits hosted in Si-based triple quantum dots do not suffer from decoherence caused by randomly fluctuating nuclear-spin ensembles and can be relatively r…
Creation of entangled atomic states by an analogue of the Dynamical Casimir Effect
K. Lange, J. Peise, B. Lücke +7
If the boundary conditions of the quantum vacuum are changed in time, quantum field theory predicts that real, observable particles can be created in the initially empty modes. Her…
