Qubit-qudit entanglement transfer in defect centers with high-spin nuclei
W. -R. Hannes, Guido Burkard
We propose a scheme for accumulating entanglement between long-lived qudits provided by central nuclear spins of defect centers. Assuming a generic setting, the electron spin of ea…
High-Fidelity Entangling Gates for Electron and Nuclear Spin Qubits in Diamond
Regina Finsterhoelzl, Wolf-Rüdiger Hannes, Guido Burkard
Motivated by the recent experimental progress in exploring the use of a nitrogen-vacancy (NV) center in diamond as a quantum computing platform, we propose schemes for fast and hig…
Fidelity of photon-mediated entanglement between remote nuclear-spin multi-qubit registers
W. -R. Hannes, Regina Finsterhoelzl, Guido Burkard
The electron spin of a nitrogen-vacancy center in diamond lends itself to the control of proximal C nuclear spins via dynamical decoupling methods, possibly combined with ra…
Quantum Hall criticality and localization in graphene with short-range impurities at the Dirac point
S. Gattenloehner, W. -R. Hannes, P. M. Ostrovsky +3
We explore the longitudinal conductivity of graphene at the Dirac point in a strong magnetic field with two types of short-range scatterers: adatoms that mix the valleys and "scala…
Finite-temperature Bell test for quasiparticle entanglement in the Fermi sea
W. -R. Hannes, M. Titov
We demonstrate that the Bell test cannot be realized at finite temperatures in the vast majority of electronic setups proposed previously for quantum entanglement generation. This…
