Giant anisotropy of spin relaxation and spin-valley mixing in a silicon quantum dot
Xin Zhang, Rui-Zi Hu, Hai-Ou Li +11
In silicon quantum dots (QDs), at a certain magnetic field commonly referred to as the "hot spot", the electron spin relaxation rate (T_1^(-1)) can be drastically enhanced due to s…
Tunable parametric amplification of a graphene nanomechanical resonator in the nonlinear regime
Zi-Jia Su, Yue Ying, Xiang-Xiang Song +6
Parametric amplification is widely used in nanoelectro-mechanical systems to enhance the transduced mechanical signals. Although parametric amplification has been studied in differ…
Coherent phonon dynamics in spatially separated graphene mechanical resonators
Zhuo-Zhi Zhang, Xiang-Xiang Song, Gang Luo +9
Vibrational modes in mechanical resonators provide a promising candidate to interface and manipulate classical and quantum information. The observation of coherent dynamics between…
Semiconductor Quantum Computation
Xin Zhang, Hai-Ou Li, Gang Cao +3
Semiconductors, a significant type of material in the information era, are becoming more and more powerful in the field of quantum information. In the last decades, semiconductor q…
Dipole coupling of a tunable hole double quantum dot in germanium hut wire to a microwave resonator
Gang Xu, Yan Li, Fei Gao +8
The germanium (Ge) hut wire system has strong spin-orbit coupling, a long coherence time due to a very large heavy-light hole splitting, and the advantage of site-controlled large-…
Improving mobility of silicon metal-oxide-semiconductor devices for quantum dots by high vacuum activation annealing
Ke Wang, Hai-Ou Li, Gang Luo +10
To improve mobility of fabricated silicon metal-oxide-semiconductor (MOS) quantum devices, forming gas annealing is a common method used to mitigate the effects of disorder at the…
