Electrically driven spin resonance with bichromatic driving
Zoltán György, András Pályi, Gábor Széchenyi
Electrically driven spin resonance (EDSR) is an established tool for controlling semiconductor spin qubits. Here, we theoretically study a frequency-mixing variant of EDSR, where t…
Parity-to-charge conversion for readout of topological Majorana qubits
Gábor Széchenyi, András Pályi
We theoretically study a scheme to distinguish the two ground states of a one-dimensional topological superconductor, which could serve as a basis for the readout of Majorana qubit…
Poor man's topological quantum gate based on the Su-Schrieffer-Heeger model
Péter Boross, János K. Asbóth, Gábor Széchenyi +2
Topological properties of quantum systems could provide protection of information against environmental noise, and thereby drastically advance their potential in quantum informatio…
Impurity-assisted electric control of spin-valley qubits in monolayer MoS
G. Széchenyi, L. Chirolli, A. Pályi
We theoretically study a single-electron spin-valley qubit in an electrostatically defined quantum dot in a transition metal dichalcogenide monolayer, focusing on the example of Mo…
Hyperfine-assisted fast electric control of dopant nuclear spins in semiconductors
Péter Boross, Gábor Széchenyi, András Pályi
Nuclear spins of dopant atoms in semiconductors are promising candidates as quantum bits, due to the long lifetime of their quantum states. Conventionally, coherent control of nucl…
Electron-electron attraction in an engineered electromechanical system
Gábor Széchenyi, András Pályi, Matthias Droth
Two electrons in a quantum dot repel each other: their interaction can be characterized by a positive interaction energy. From the theory of superconductivity, we also know that me…
Coulomb-blockade and Pauli-blockade magnetometry
Gábor Széchenyi, András Pályi
Scanning-probe magnetometry is a valuable experimental tool to investigate magnetic phenomena at the micro- and nanoscale. We theoretically analyze the possibility of measuring mag…
Control of valley dynamics in silicon quantum dots in the presence of an interface step
Péter Boross, Gábor Széchenyi, Dimitrie Culcer +1
Recent experiments on silicon nanostructures have seen breakthroughs toward scalable, long-lived quantum information processing. The valley degree of freedom plays a fundamental ro…
Shape-sensitive Pauli blockade in a bent carbon nanotube
Gábor Széchenyi, András Pályi
Motivated by a recent experiment [F. Pei et al., Nat. Nanotech. 7, 630 (2012)], we theoretically study the Pauli blockade transport effect in a double quantum dot embedded in a ben…
Maximal Rabi frequency of an electrically driven spin in a disordered magnetic field
Gábor Széchenyi, András Pályi
We present a theoretical study of the spin dynamics of a single electron confined in a quantum dot. Spin dynamics is induced by the interplay of electrical driving and the presence…
