Spin-qubit readout analysis based on a hidden Markov model

Maria Spethmann, Peter Stano, Daniel Loss

Across most qubit platforms, the readout fidelities do not keep up with the gate fidelities, and new ways to increase the readout fidelities are searched for. For semiconductor spi…

Magnetic ordering tendencies in hexagonal boron nitride-bilayer graphene moiré structures

Maria Spethmann, Carsten Honerkamp, Dante M. Kennes

When hexagonal boron nitride (hBN) and graphene are aligned at zero or small twist angle, a moiré structure is formed due to the small lattice constant mismatch between the two str…
