Superradiant-like dynamics by electron shuttling on a nuclear-spin island
Yi-Nan Fang, Ying-Dan Wang, Rosario Fazio +1
We investigate superradiant-like dynamics of the nuclear-spin bath in a single-electron quantum dot, by considering electrons cyclically shuttling on/off an isotopically enriched `…
Optimization of STIRAP-based state transfer under dissipation
Ying-Dan Wang, Xiao-Bo Yan, Stefano Chesi
Using a perturbative treatment, we quantify the influence of non-adiabatic leakage and system dissipation on the transfer fidelity of a stimulated Raman adiabatic passage (STIRAP)…
Single-spin manipulation in a double quantum dot in the field of a micromagnet
Stefano Chesi, Ying-Dan Wang, Jun Yoneda +3
The manipulation of single spins in double quantum dots by making use of the exchange interaction and a highly inhomogeneous magnetic field was discussed in [W. A. Coish and D. Los…
Diabolical points in multi-scatterer optomechanical systems
Stefano Chesi, Ying-Dan Wang, Jason Twamley
Diabolical points, which originate from parameter-dependent accidental degeneracies of a system's energy levels, have played a fundamental role in the discovery of the Berry phase…
Reservoir-engineered entanglement in optomechanical systems
Ying-Dan Wang, Aashish A. Clerk
We show how strong steady-state entanglement can be achieved in a three-mode optomechanical system (or other parametrically-coupled bosonic system) by using one of the modes as a c…
Using dark modes for high-fidelity optomechanical quantum state transfer
Ying-Dan Wang, Aashish A. Clerk
In a recent publication [Y.D. Wang and A.A. Clerk, Phys. Rev. Lett. 108, 153603 (2012)], we demonstrated that one can use interference to significantly increase the fidelity of sta…
Using interference for high fidelity quantum state transfer in optomechanics
Ying-Dan Wang, Aashish A. Clerk
We revisit the problem of using a mechanical resonator to perform the transfer of a quantum state between two electromagnetic cavities (e.g. optical and microwave). We show that th…
