Stability of the discrete time-crystalline order in spin-optomechanical and open cavity QED systems
Zhengda Hu, Xingyu Gao, Tongcang Li
Discrete time crystals (DTC) have been demonstrated experimentally in several different quantum systems in the past few years. Spin couplings and cavity losses have been shown to p…
High-contrast plasmonic-enhanced shallow spin defects in hexagonal boron nitride for quantum sensing
Xingyu Gao, Boyang Jiang, Andres E. Llacsahuanga Allcca +9
The recently discovered spin defects in hexagonal boron nitride (hBN), a layered van der Waals material, have great potential in quantum sensing. However, the photoluminescence and…
Femtosecond Laser Writing of Spin Defects in Hexagonal Boron Nitride
Xingyu Gao, Siddhant Pandey, Mehran Kianinia +5
Optically active spin defects in wide-bandgap materials have many potential applications in quantum information and quantum sensing. Spin defects in two-dimensional layered van der…
Classical and quantum time crystals in a levitated nanoparticle without drive
Yi Huang, Qihao Guo, Anda Xiong +2
Time crystal is defined as a phase of matter spontaneously exhibiting a periodicity in time. Previous studies focused on discrete quantum time crystals under periodic drive. Here,…
Preparing squeezed spin states in a spin-mechanical hybrid system with silicon-vacancy centers
Bo Li, Xiaoxiao Li, Pengbo Li +1
We present and analyze an effective scheme for preparing squeezed spin states in a novel spin-mechanical hybrid device, which is realized by a single crystal diamond waveguide with…
Quantum information processing with closely-spaced diamond color centers in strain and magnetic fields
Zhujing Xu, Zhang-qi Yin, Qinkai Han +1
Electron and nuclear spins of diamond nitrogen-vacancy (NV) centers are good candidates for quantum information processing as they have long coherence time and can be initialized a…
