Braiding-based quantum control of a Majorana qubit built from quantum dots
Péter Boross, András Pályi
Topology-related ideas might lead to noise-resilient quantum computing. For example, it is expected that the slow spatial exchange (`braiding') of Majorana zero modes in supercondu…
Dephasing of Majorana qubits due to quasistatic disorder
Péter Boross, András Pályi
Quantum bits based on Majorana zero modes are expected to be robust against certain noise types, and hence provide a quantum computing platform that is superior to conventional qub…
Triplet-blockaded Josephson supercurrent in double quantum dots
Daniël Bouman, Ruben J. J. van Gulik, Gorm Steffensen +7
Serial double quantum dots created in semiconductor nanostructures provide a versatile platform for investigating two-electron spin quantum states, which can be tuned by electrosta…
Hyperfine-assisted decoherence of a phosphorus nuclear-spin qubit in silicon
Bence Hetényi, Péter Boross, András Pályi
The nuclear spin of a phosphorus atom in silicon has been used as a quantum bit in various quantum-information experiments. It has been proposed that this nuclear-spin qubit can be…
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…
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…
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…
Valley-enhanced fast relaxation of gate-controlled donor qubits in silicon
Péter Boross, Gábor Széchenyi, András Pályi
Gate control of donor electrons near interfaces is a generic ingredient of donor-based quantum computing. Here, we address the question: how is the phonon-assisted qubit relaxation…
Valley relaxation in graphene due to charged impurities
Péter Boross, András Pályi
Monolayer graphene is an example of materials with multi-valley electronic structure. In such materials, the valley index is being considered as an information carrier. Consequentl…
