Generating the Schrodinger cat state in a nanomechanical resonator coupled to a charge qubit
Jian-Qi Zhang, Wei Xiong, Shuo Zhang +2
We propose a scheme for generating the Schrödinger cat state based on geometric operations by a nanomechanical resonator coupled to a superconducting charge qubit. The charge qubit…
Fast optical cooling of nanomechanical cantilever with the dynamical Zeeman effect
Jian-Qi Zhang, Shuo Zhang, Jin-Hua Zou +4
We propose an efficient optical electromagnetically induced transparency (EIT) cooling scheme for a cantilever with a nitrogen-vacancy center attached in a non-uniform magnetic fie…
Cooling a charged mechanical resonator with time-dependent bias gate voltages
Jian-Qi Zhang, Yong Li, Mang Feng
We show a purely electronic cooling scheme to cool a charged mechanical resonator (MR) down to nearly the vibrational ground state by elaborately tuning bias gate voltages on the e…
Precision measurement of charge number with optomechanically induced transparency
Jian-Qi Zhang, Yong Li, Mang Feng +1
We propose a potentially practical scheme to precisely measure the charge numbers of small charged objects by optomechanical systems using optomechanically induced transparency (OM…
