Controlled-Not Quantum Logic Gate in Two Strongly Coupled Semiconductor Charge Qubits
Hai-Ou Li, Gang Cao, Guo-Dong Yu +4
A crucial requirement for scalable quantum-information processing is the realization of multiple-qubit quantum gates. Universal multiple-qubit gates can be implemented by a set of…
Giant spin-torque diode sensitivity at low input power in the absence of bias magnetic field
Bin Fang, Mario Carpentieri, Xiaojie Hao +11
Microwave detectors based on the spin-transfer torque diode effect are among the key emerging spintronic devices. By utilizing the spin of electrons in addition to charge, they hav…
Coupling two distant double quantum dots to a microwave resonator
Guang-Wei Deng, Da Wei, Shu-Xiao Li +9
With recent advances in the circuit quantum electrodynamics (cQED) architecture, hybrid systems that couple nano-devices to microwave resonators have been developing rapidly. Here…
Fabrication and characterization of an undoped GaAs/AlGaAs quantum dot device
Hai-Ou Li, Gang Cao, Ming Xiao +6
We demonstrate the development of a double quantum dot with an integrated charge sensor fabricated in undoped GaAs/AlGaAs heterostructures using a double top-gated design. Based on…
Suspending Effect on Low-Frequency Charge Noise in Graphene Quantum Dot
Xiang-Xiang Song, Hai-Ou Li, Jie You +7
Charge noise is critical in the performance of gate-controlled quantum dots (QDs). Here we show the 1/f noise for a microscopic graphene QD is substantially larger than that for a…
