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…
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…
Entangled-state generation and Bell inequality violations in nanomechanical resonators
J. Robert Johansson, Neill Lambert, Imran Mahboob +2
We investigate theoretically the conditions under which a multi-mode nanomechanical resonator, operated as a purely mechanical parametric oscillator, can be driven into highly nonc…
