Quantum simulation of Kibble-Zurek mechanism with a semiconductor electron charge qubit
Cheng Zhou, Li Wang, Tao Tu +4
The Kibble-Zurek mechanism provides a description of the topological structure occurring in the symmetry breaking phase transitions, which may manifest as the cosmological strings…
Electron Spin Excited States Spectroscopy in a Quantum Dot Probed by QPC Back-action
HaiOu Li, Ming Xiao, Gang Cao +6
The quantum point contact (QPC) back-action has been found to cause non-thermal-equilibrium excitations to the electron spin states in a quantum dot (QD). Here we use back-action a…
Back-action Driven Electron Spin Singlet-Triplet Excitation in a GaAs Quantum Dot
Gang Cao, Ming Xiao, HaiOu Li +6
In a single quantum dot (QD), the electrons were driven out of thermal equilibrium by the back-action from a nearby quantum point contact (QPC). We found the driving to energy exci…
Back-action Induced Non-equilibrium Effect in Electron Charge Counting Statistics
HaiOu Li, Ming Xiao, Gang Cao +6
We report our study of the real-time charge counting statistics measured by a quantum point contact (QPC) coupled to a single quantum dot (QD) under different back-action strength.…
Molecule States in a Gate Tunable Graphene Double Quantum Dot
L. J. Wang, H. O. Li, Z. Su +6
We have measured a graphene double quantum dot device with multiple electrostatic gates that are used to enhance control to investigate it. At low temperatures the transport measur…
A Graphene Quantum Dot with a Single Electron Transistor as Integrated Charge Sensor
Ling-Jun Wang, Gang Cao, Tao Tu +7
We have developed an etching process to fabricate a quantum dot and a nearby single electron transistor as a charge detector in a single layer graphene. The high charge sensitivity…
