A feasible strategy to balance the crystallinity and specific surface area of metal oxide nanocrystals
(2017)Practical, efficient synthesis of metal oxide nanocrystals with good crystallinity and high specific surface area by a modified polymernetwork gel method is demonstrated, taking ZnO nanocrystals as an example. A novel ... 
Pseudotopotactic conversion of carbon nanotubes to Tcarbon nanowires under picosecond laser irradiation in methanol

(2018)We propose a superconducting circuitatom hybrid, where the Rabi oscillation of single excess Cooper pair in the island is stabilized via the common atomic clock technique. The noise in the superconducting circuit is mapped ... 
Squeezing Enhances Quantum Synchronization
(2018)It is desirable to observe synchronization of quantum systems in the quantum regime, defined by the low number of excitations and a highly nonclassical steady state of the selfsustained oscillator. Several existing proposals ...

Separability criteria with angular and Hilbert space averages
(2016)The practically useful criteria of separable states ρ=∑k wkρk in d=2×2 are discussed. The equality G(a,b)=4[〈ψP(a)⊗P(b)ψ〉−〈ψP(a)⊗1ψ〉〈ψ1⊗P(b)ψ〉]=0 for any two projection operators P(a) and P(b) provides a necessary ... 
Fast nonAbelian geometric gates via transitionless quantum driving
(20151221)A practical quantum computer must be capable of performing high fidelity quantum gates on a set of quantum bits (qubits). In the presence of noise, the realization of such gates poses daunting challenges. Geometric phases, ... 
GdN thin film: Chern insulating state on square lattice
