Observation of Kondo Effect in a Quadruple Quantum Dots
Runan Shang, Hai-Ou Li, Gang Cao +7
We investigate the Kondo effect in a quadruple quantum dot device of coupled-double quantum dots (DQDs), which simultaneously contains intra-DQDs and inter-DQDs coupling. A variety…
Charge Number Dependence of the Dephasing Rates of a Graphene Double Quantum Dot in a Circuit QED Architecture
Guang-Wei Deng, Da Wei, J. R. Johansson +10
We use an on-chip superconducting resonator as a sensitive meter to probe the properties of graphene double quantum dots at microwave frequencies. Specifically, we investigate the…
Detection and measurement of spin-dependent dynamics in random telegraph signals
M. G. House, Ming Xiao, GuoPing Guo +4
A quantum point contact was used to observe single-electron fluctuations of a quantum dot in a GaAs heterostructure. The resulting random telegraph signals (RTS) contain statistica…
Symmetric reflection line resonator for semiconductor circuit quantum electrodynamics
Miao-Lei Zhang, Guang-Wei Deng, Shu-Xiao Li +8
We have designed and fabricated a half-wavelength reflection line resonator (RLR) that consists of a pair of two coupled microstrip lines on a GaAs/AlGaAs heterostructure. By chang…
Photon-assisted-tunneling in a coupled double quantum dot out of thermal equilibrium
Runan Shang, Haiou Li, Gang Cao +5
We perform photon-assisted-tunneling (PAT) experiments on a GaAs double quantum dot device under high microwave excitation power. Photon-assisted absorption of up to 14 photons is…
Tuning inter-dot tunnel coupling of an etched graphene double quantum dot by adjacent metal gates
Da Wei, Hai-Ou Li, Gang Cao +7
Graphene double quantum open the possibility to use charge or spin degrees of freedom for storing and manipulating quantum information in this new electronic material. However, imp…
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…
