Signatures of atomic-scale structure in the energy dispersion and coherence of a Si quantum-dot qubit
J. C. Abadillo-Uriel, Brandur Thorgrimsson, Dohun Kim +11
We report anomalous behavior in the energy dispersion of a three-electron double-quantum-dot hybrid qubit and argue that it is caused by atomic-scale disorder at the quantum-well i…
Extending the coherence of a quantum dot hybrid qubit
Brandur Thorgrimsson, Dohun Kim, Yuan-Chi Yang +10
Identifying and ameliorating dominant sources of decoherence are important steps in understanding and improving quantum systems. Here we show that the free induction decay time ($T…
Identifying single electron charge sensor events using wavelet edge detection
J. R. Prance, B. J. Van Bael, C. B. Simmons +5
The operation of solid-state qubits often relies on single-shot readout using a nanoelectronic charge sensor, and the detection of events in a noisy sensor signal is crucial for hi…
High fidelity resonant gating of a silicon based quantum dot hybrid qubit
Dohun Kim, D. R. Ward, C. B. Simmons +5
Isolated spins in semiconductors provide a promising platform to explore quantum mechanical coherence and develop engineered quantum systems. Silicon has attracted great interest a…
Microwave-driven coherent operations of a semiconductor quantum dot charge qubit
Dohun Kim, D. R. Ward, C. B. Simmons +8
A most intuitive realization of a qubit is a single electron charge sitting at two well-defined positions, such as the left and right sides of a double quantum dot. This qubit is n…
Quantum control and process tomography of a semiconductor quantum dot hybrid qubit
Dohun Kim, Zhan Shi, C. B. Simmons +9
The similarities between gated quantum dots and the transistors in modern microelectronics - in fabrication methods, physical structure, and voltage scales for manipulation - have…
