Improving the coherence time of a quantum system via a coupling with an unstable system
Yuichiro Matsuzaki, Xiaobo Zhu, Kosuke Kakuyanagi +8
Here, we propose a counter-intuitive use of a hybrid system where the coherence time of a quantum system is actually improved via a coupling with an unstable system. If we couple a…
