Extremum seeking control of quantum gates
Erfan Abbasgholinejad, Haoqin Deng, John Gamble +4
To be useful for quantum computation, gate operations must be maintained at high fidelities over long periods of time. In addition to decoherence, slow drifts in control hardware l…
Density dependence of the excitation gaps in an undoped Si/SiGe double-quantum-well heterostructure
D. Chen, S. Cai, N. -W. Hsu +7
We report low-temperature magneto-transport measurements of an undoped Si/SiGe asymmetric double quantum well heterostructure. The density in both layers is tuned independently uti…
Scalable gate architecture for densely packed semiconductor spin qubits
D. M. Zajac, T. M. Hazard, X. Mi +2
We demonstrate a 12 quantum dot device fabricated on an undoped Si/SiGe heterostructure as a proof-of-concept for a scalable, linear gate architecture for semiconductor quantum dot…
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…
Efficient self-consistent quantum transport simulator for quantum devices
Xujiao Gao, Denis Mamaluy, Erik Nielsen +6
We present a self-consistent one-dimensional (1D) quantum transport simulator based on the Contact Block Reduction (CBR) method, aiming for very fast and robust transport simulatio…
Spontaneous emission in a silicon charge qubit
Khoi T. Nguyen, N. Tobias Jacobson, Michael P. Lilly +6
The interaction between a qubit and its environment provides a channel for energy relaxation which has an energy-dependent timescale governed by the specific coupling mechanism. We…
