Quantum scrambling in a toy model of photodetectors
Yubao Liu, Haixing Miao, Yanbei Chen +1
Quantum measurement is a process that involves the interaction between a quantum system and a macroscopic measurement apparatus containing many degrees of freedom. The photodetecto…
Semi-classical gravity phenomenology under the causal-conditional quantum measurement prescription
Yubao Liu, Haixing Miao, Yanbei Chen +1
The semi-classical gravity sourced by the quantum expectation value of the matter's energy-momentum tensor will change the evolution of the quantum state of matter. This effect can…
Scalable Simulation of Quantum Measurement Process with Quantum Computers
Meng-Jun Hu, Yanbei Chen, Yiqiu Ma +4
Recent development in quantum information sciences and technologies, especially building programmable quantum computers, provide us new opportunities to study fundamental aspects o…
A Hybrid Rydberg Quantum Gate for Quantum Network
Yubao Liu, Lin Li, Yiqiu Ma
The high fidelity storage, distribution and processing of quantum information prefers qubits with different physical properties. Thus, hybrid quantum gates interfacing different ty…
Enhancing interferometer sensitivity without sacrificing bandwidth and stability: beyond single-mode and resolved-sideband approximation
Xiang Li, Jiri Smetana, Amit Singh Ubhi +5
Quantum noise limits the sensitivity of precision measurement devices, such as laser interferometer gravitational-wave observatories and axion detectors. In the shot-noise-limited…
Broadband sensitivity improvement via coherent quantum feedback with PT symmetry
Xiang Li, Maxim Goryachev, Yiqiu Ma +4
A conventional resonant detector is often subject to a trade-off between bandwidth and peak sensitivity that can be traced back to quantum Cramer-Rao Bound. Anomalous dispersion ha…
