Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Cooperation between Coherent Control and Noises in Quantum Metrology
量子计量 相干控制 噪声

In this work, the cooperation between coherent control and noises in open spin systems is studied, aiming to demonstrate that such cooperation can provide new possibilities for parametrization in quan...
Quantum Metrology with Dicke Squeezed States
quantum metrology Dicke squeezed state entanglement
2016/1/22
We introduce a new class of quantum many-particle entangled states, called the Dicke squeezed (or DS) states, which can be used to improve the precision in quantum metrology beyond the standard quantu...
Quantum metrology to probe atomic parity nonconservation
Quantum metrology probe atomic parity nonconservation

An entangled state prepared in a decoherence free sub-space together with a Ramsey type measurement can probe parity violation in heavy alkali ions like Ba+ or Ra+. Here we propose an experiment with ...
