Quantum Metrology via Adiabatic Control of Topological Edge States
Xingjian He, Aoqian Shi, Jianjun Liu +1
Criticality-based quantum sensing exploits hypersensitive response to system parameters near phase transition points. This work uncovers two metrological advantages offered by topo…

Using coherent feedback for a periodic clock
Stefan Zeppetzauer, Leonardo Assis Morais, Xin He +2
A driven linear oscillator and a feedback mechanism are two necessary elements of any classical periodic clock. Here, we introduce a novel, fully quantum clock using a driven oscil…
