Room-temperature ultra-sensitive mass spectrometer via dynamic decoupling
Nan Zhao, Zhang-qi Yin
We propose an ultra-sensitive mass spectrometer based on a coupled quantum-bit-oscillator system. Under dynamical decoupling control of the quantum bit (qubit), the qubit coherence…
Optomechanics of Levitated Dielectric Particles
Zhang-qi Yin, Andrew A. Geraci, Tongcang Li
We review recent works on optomechanics of optically trapped microspheres and nanoparticles in vacuum, which provide an ideal system for studying macroscopic quantum mechanics and…
Large quantum superpositions of a levitated nanodiamond through spin-optomechanical coupling
Zhang-qi Yin, Tongcang Li, Xiang Zhang +1
We propose a method to generate and detect large quantum superposition states and arbitrary Fock states for the oscillational mode of an optically levitated nanocrystal diamond. Th…
Topological quantum memory interfacing atomic and superconducting qubits
Zheng-Yuan Xue, Zhang-qi Yin, Yan Chen +2
We propose a scheme to manipulate a topological spin qubit which is realized with cold atoms in a one-dimensional optical lattice. In particular, by introducing a quantum opto-elec…
