Tomography of a Macroscopic Quantum State influenced by Classical Self-Gravity
Wenjie Zhong, Yubao Liu, Yanbei Chen +2
Macroscopic optomechanical systems offer a promising testbed for distinguishing whether gravity acts as a quantum interaction or as a classical field. Schrodinger-Newton (SN) theor…
Testing the quantum nature of gravity through interferometry
Yubao Liu, Yanbei Chen, Kentaro Somiya +1
We propose a Michelson-type interferometric protocol for testing the quantum nature of gravity through testing the phenomenology of semi-classical gravity theory, which predicts a…
Distinguishing Quantum and Classical Gravity via Non-Stationary Test Mass Dynamics
Wenjie Zhong, Yubao Liu, Yiqiu Ma
Classical gravity theory predicts a state-dependent gravitational potential for a quantum test mass, leading to nonlinear Schrodinger-Newton (SN) state evolution that contrasts wit…
The Role of Quantum Measurements when Testing the Quantum Nature of Gravity
Daisuke Miki, Youka Kaku, Yubao Liu +2
In order to test the quantum nature of gravity, it is essential to explore the construction of classical gravity theories that are as consistent with experiments as possible. In pa…
Semiclassical gravity phenomenology under the causal-conditional quantum measurement prescription II: Heisenberg picture and apparent optical entanglement
Yubao Liu, Wenjie Zhong, Yanbei Chen +1
The evolution of quantum states influenced by semiclassical gravity is distinct from that in quantum gravity theory due to the presence of a state-dependent gravitational potential…
First result for testing semiclassical gravity effect with a torsion balance
Tianliang Yan, Yubao Liu, Leonid Prokhorov +5
The Schrödinger-Newton equation, a theoretical framework connecting quantum mechanics with classical gravity, predicts that gravity may induce measurable deviations in low-frequenc…
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…
