Significant enhancement in refrigeration and entanglement in auxiliary-cavity-assisted optomechanical systems
Deng-Gao Lai, Wei Qin, Bang-Pin Hou +2
We propose how to achieve significantly enhanced quantum refrigeration and entanglement by coupling a pumped auxiliary cavity to an optomechanical cavity. We obtain both analytical…
In-plane critical magnetic fields in magic-angle twisted trilayer graphene
Wei Qin, Allan H. MacDonald
It has recently been shown that superconductivity in magic-angle twisted trilayer graphene survives to in-plane magnetic fields that are well in excess of the Pauli limit, and much…
Critical magnetic fields and electron-pairing in magic-angle twisted bilayer graphene
Wei Qin, Bo Zou, Allan H. MacDonald
The velocities of the quasiparticles that form Cooper pairs in a superconductor are revealed by the upper critical magnetic field. Here we use this property to assess superconducti…
Generating Large Cats with Nine Lives: Long-Lived Macroscopically Distinct Superposition States in Atomic Ensembles
Wei Qin, Adam Miranowicz, Hui Jing +1
We propose to create and stabilize long-lived macroscopic quantum superposition states in atomic ensembles. We show that using a fully quantum parametric amplifier can cause the si…
Fast binomial-code holonomic quantum computation with ultrastrong light-matter coupling
Ye-Hong Chen, Wei Qin, Roberto Stassi +2
We propose a protocol for bosonic binomial-code nonadiabatic holonomic quantum computation in a system composed of an artificial atom ultrastrongly coupled to a cavity resonator. I…
Chiral topological superconducting state with Chern number in PbBi/Ge(111)
Shuwen Sun, Wei Qin, Leiqiang Li +1
Materials realization of chiral topological superconductivity is a crucial condition for observing and manipulating Majorana fermions in condensed matter physics. Here we develop a…
