Sub-SQL electronic field sensing by simultaneously using quantum entanglements and squeezings
X. N. Feng, M. Zhang, L. F. Wei
Quantum entanglement and quantum squeezing are two most typical approaches to beat the standard quantum limit (SQL) of the sensitive phase estimations in quantum metrology. Each of…
Sensitive detection of local magnetic field changes with atomic interferometry by using superconducting Meissner effects
Y. Q. Chai, M. Zhang, L. F. Wei
Sensitive detection of magnetic field is one of the open problem in metrology. Here, we propose an Mach-Zehnder atomic interferometry to sensitively detect the very weak local magn…
Controlled splitting of an atomic wave packet
M. Zhang, P. Zhang, M. S. Chapman +1
We propose a simple scheme capable of adiabatically splitting an atomic wave packet using two independent translating traps. Implemented with optical dipole traps, our scheme allow…
Tunnelling of condensate magnetization in a double-well potential
Ö. E. Müstecaplıoğlu, M. Zhang, L. You
We study quantum dynamical properties of a spin-1 atomic Bose-Einstein condensate in a double-well potential. Adopting a mean field theory and single spatial mode approximation, we…
