Nonadiabatic dynamics and geometric phase of an ultrafast rotating electron spin
Xing-Yan Chen, Tongcang Li, Zhang-qi Yin
The spin in a rotating frame has attracted a lot of attentions recently, as it deeply relates to both fundamental physics such as pseudo-magnetic field and geometric phase, and app…

Universal quantum gates between nitrogen-vacancy centers in a levitated nanodiamond
Xing-Yan Chen, Zhang-qi Yin
We propose a scheme to realize universal quantum gates between nitrogen-vacancy (NV) centers in an optically trapped nanodiamond, through uniform magnetic field induced coupling be…

High-precision gravimeter based on a nano-mechanical resonator hybrid with an electron spin
Xing-yan Chen, Zhang-qi Yin
We show that the gravitational acceleration can be measured with the matter-wave Ramsey interferometry, by using a nitrogen-vacancy center coupled to a nano-mechanical resonator. W…
