Time-crystalline behavior in central-spin models with Heisenberg interactions
Rafail Frantzeskakis, John Van Dyke, Leon Zaporski +5
Time-crystalline behavior has been predicted and observed in quantum central-spin systems with periodic driving and Ising interactions. Here, we theoretically show that it can also…
Hyperfine-interaction limits polarization entanglement of photons from semiconductor quantum dots
Christian Schimpf, Francesco Basso Basset, Maximilian Aigner +12
Excitons in quantum dots are excellent sources of polarization-entangled photon pairs, but a quantitative understanding of their interaction with the nuclear spin bath is still mis…
A many-body singlet prepared by a central spin qubit
Leon Zaporski, Stijn R. de Wit, Takuya Isogawa +4
Controllable quantum many-body systems are platforms for fundamental investigations into the nature of entanglement and promise to deliver computational speed-up for a broad class…
