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 randomized benchmarking of quantum computers using mirror circuits
Timothy Proctor, Stefan Seritan, Kenneth Rudinger +3
The performance of quantum gates is often assessed using some form of randomized benchmarking. However, the existing methods become infeasible for more than approximately five qubi…
Two-qubit silicon quantum processor with operation fidelity exceeding 99%
A. R. Mills, C. R. Guinn, M. J. Gullans +4
Silicon spin qubits satisfy the necessary criteria for quantum information processing. However, a demonstration of high fidelity state preparation and readout combined with high fi…
Precision tomography of a three-qubit donor quantum processor in silicon
Mateusz T. Mądzik, Serwan Asaad, Akram Youssry +17
Nuclear spins were among the first physical platforms to be considered for quantum information processing, because of their exceptional quantum coherence and atomic-scale footprint…
Experimental Characterization of Crosstalk Errors with Simultaneous Gate Set Tomography
Kenneth Rudinger, Craig W. Hogle, Ravi K. Naik +11
Crosstalk is a leading source of failure in multiqubit quantum information processors. It can arise from a wide range of disparate physical phenomena, and can introduce subtle corr…
Characterizing mid-circuit measurements on a superconducting qubit using gate set tomography
Kenneth Rudinger, Guilhem J. Ribeill, Luke C. G. Govia +6
Measurements that occur within the internal layers of a quantum circuit -- mid-circuit measurements -- are an important quantum computing primitive, most notably for quantum error…
