Enhancement of Quantum Sensing in a Cavity Optomechanical System around Quantum Critical Point
Shao-Bo Tang, Hao Qin, D. -Y. Wang +4
The precision of quantum sensing could be improved by exploiting quantum phase transitions, where the physical quantity tends to diverge when the system approaches the quantum crit…
Scalable quantum logic spectroscopy
Kaifeng Cui, Jose Valencia, Kevin T. Boyce +2
In quantum logic spectroscopy (QLS), one species of trapped ion is used as a sensor to detect the state of an otherwise inaccessible ion species. This extends precision measurement…
Black hole as fireplace: limited communications across the horizon
Liangsuo Shu, Kaifeng Cui, Xiaokang Liu +2
An insightful viewpoint was proposed by Susskind about AMPS firewall: the region behind the firewall does not exist and the firewall is an extension of the singularity. In this wor…
Phase transition of spacetime: particles as black holes in anti-de Sitter space
Liangsuo Shu, Kaifeng Cui, Xiaokang Liu +1
In this work, we re-examined the ancient complex metric in the recent quantum picture of black holes as Bose-Einstein condensates of gravitons. Both black holes and particles can b…
Surface tension of the horizon
Liangsuo Shu, Kaifeng Cui, Xiaokang Liu +2
The idea of treating the horizon of a black hole as a stretched membrane with surface tension has a long history. In this work, we discuss the microscopic origin of the surface ten…
Fluctuation and Inertia
Liangsuo Shu, Xiaokang Liu, Kaifeng Cui +2
In this work, using Jacobson's idea: 'Q=TdS hold for all the local Rindler causal horizons through each spacetime point', we found that the transitions between the excited and g…
A transportable 40Ca+ single-ion clock with systematic uncertainty
Jian Cao, Ping Zhang, Junjuan Shang +6
A transportable optical clock refer to the electric quadrupole transition at 729 nm of single trapped in mini Paul trap has been developed. Th…
Sympathetic cooling of - ion pair crystal in a linear Paul trap
Jun-juan Shang, Kai-feng Cui, Jian Cao +3
The Al ion optical clock is one of the most attractive optical clocks due to its own advantages, such as low blackbody radiation shift at room temperature and insensitiv…
