Probabilistic error cancellation for dynamic quantum circuits
Riddhi S. Gupta, Ewout van den Berg, Maika Takita +3
Probabilistic error cancellation (PEC) is a technique that generates error-mitigated estimates of expectation values from ensembles of quantum circuits. In this work we extend the…
Encoding a magic state with beyond break-even fidelity
Riddhi S. Gupta, Neereja Sundaresan, Thomas Alexander +10
To run large-scale algorithms on a quantum computer, error-correcting codes must be able to perform a fundamental set of operations, called logic gates, while isolating the encoded…
Integration of spectator qubits into quantum computer architectures for hardware tuneup and calibration
Riddhi S. Gupta, Luke C. G. Govia, Michael J. Biercuk
Performing efficient quantum computer tuneup and calibration is essential for growth in system complexity. In this work we explore the link between facilitating such capabilities a…
Adaptive filtering of projective quantum measurements using discrete stochastic methods
Riddhi S. Gupta, Michael J. Biercuk
Adaptive filtering is a powerful class of control theoretic concepts useful in extracting information from noisy data sets or performing forward prediction in time for a dynamic sy…
Autonomous adaptive noise characterization in quantum computers
Riddhi Swaroop Gupta, Alistair R. Milne, Claire L. Edmunds +2
New quantum computing architectures consider integrating qubits as sensors to provide actionable information useful for decoherence mitigation on neighboring data qubits, but littl…
Machine learning for predictive estimation of qubit dynamics subject to dephasing
Riddhi Swaroop Gupta, Michael J. Biercuk
Decoherence remains a major challenge in quantum computing hardware and a variety of physical-layer controls provide opportunities to mitigate the impact of this phenomenon through…
