Magnetic degeneracy points in interacting two-spin systems: geometrical patterns, topological charge distributions, and their stability
György Frank, Zoltán Scherübl, Szabolcs Csonka +2
Spectral degeneracies of quantum magnets are often described as diabolical points or magnetic Weyl points, which carry topological charge. Here, we study a simple, yet experimental…
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…
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…
