Robust entanglement-based magnetic field sensor beyond the standard quantum limit
Tohru Tanaka, Paul Knott, Yuichiro Matsuzaki +4
Recently, there have been significant developments in entanglement-based quantum metrology. However, entanglement is fragile against experimental imperfections, and quantum sensing…
Using the Quantum Zeno Effect for Suppression of Decoherence
Yasushi Kondo, Yuichiro Matsuzaki, Kei Matsushima +1
Projective measurements are an essential element of quantum mechanics. In most cases, they cause an irreversible change of the quantum system on which they act. However, measuremen…
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…
