Trapping quantum coherence with a dissipative thermal bath
Jia-Ming Zhang, Bing Chen, Jun Jing
In the long-time limit, an open quantum system coupled to a dissipative environment is believed to lose its coherence without driving or measurement. Counterintuitively, we provide…
Charging by quantum measurement
Jia-shun Yan, Jun Jing
We propose a quantum charging scheme fueled by measurements on ancillary qubits serving as disposable chargers. A stream of identical qubits are sequentially coupled to a quantum b…
Measurement-induced nuclear spin polarization
Zhu-yao Jin, Jia-shun Yan, Jun Jing
We propose a nuclear-spin-polarization protocol in a general evolution-and-measurement framework. The protocol works in a spin-star configuration, where the central spin is coupled…
Floquet generation of magnonic NOON state
Shi-fan Qi, Jun Jing
We propose a concise and deterministic protocol to generate NOON states in a hybrid system consisting of a superconducting qubit, a circuit resonator mode, and two magnonic modes,…
Chiral current in Floquet cavity-magnonics
Shi-fan Qi, Jun Jing
Floquet engineering can induce complex collective behaviour and interesting synthetic gauge-field in quantum systems through temporal modulation of system parameters by periodic dr…
Optimizing measurement-based cooling by reinforcement learning
Jia-shun Yan, Jun Jing
Conditional cooling-by-measurement holds a significant advantage over its unconditional (nonselective) counterpart in the average-population-reduction rate. However, it has a clear…
