Two-qubit logic with anisotropic exchange in a fin field-effect transistor
Simon Geyer, Bence Hetényi, Stefano Bosco +7
Semiconductor spin qubits offer a unique opportunity for scalable quantum computation by leveraging classical transistor technology. Hole spin qubits benefit from fast all-electric…
Long-distance coupling of spin qubits via topological magnons
Bence Hetényi, Alexander Mook, Jelena Klinovaja +1
We consider two distant spin qubits in quantum dots, both coupled to a two-dimensional topological ferromagnet hosting chiral magnon edge states at the boundary. The chiral magnon…
Anomalous zero-field splitting for hole spin qubits in Si and Ge quantum dots
Bence Hetényi, Stefano Bosco, Daniel Loss
An anomalous energy splitting of spin triplet states at zero magnetic field has recently been measured in germanium quantum dots. This zero-field splitting could crucially alter th…
Crossed Andreev reflection in spin-polarized chiral edge states due to the Meissner effect
Tamás Haidekker Galambos, Flavio Ronetti, Bence Hetényi +2
We consider a hybrid quantum Hall-superconductor system, where a superconducting finger with oblique profile is wedged into a two-dimensional electron gas in the presence of a perp…
