Superconducting qubit decoherence correlated with detected radiation events
A. R. Castelli, K. M. Beck, L. D. H. Alegria +6
Most quantum error correction (QEC) protocols for superconducting qubits assume spatially and temporally uncorrelated decoherence events; however, recent evidence suggests that cos…
Direct pulse-level compilation of arbitrary quantum logic gates on superconducting qutrits
Yujin Cho, Kristin M. Beck, Alessandro R. Castelli +4
Advanced simulations and calculations on quantum computers require high-fidelity implementations of quantum operations. The universal gateset approach builds complex unitaries from…
A Simulation Methodology for Superconducting Qubit Readout Fidelity
Hiu Yung Wong, Yaniv Jacob Rosen, Kristin M. Beck +1
Qubit readout is a critical part of any quantum computer including the superconducting-qubit-based one. The readout fidelity is affected by the readout pulse width, readout pulse e…
Feasibility study of quantum computing using trapped electrons
Qian Yu, Alberto M. Alonso, Jackie Caminiti +7
We investigate the feasibility of using electrons in a linear Paul trap as qubits in a future quantum computer. We discuss the necessary experimental steps to realize such a device…
One- and two-qubit gate infidelities due to motional errors in trapped ions and electrons
R. Tyler Sutherland, Qian Yu, Kristin M. Beck +1
In this work, we derive analytic formulae that determine the effect of error mechanisms on one- and two-qubit gates in trapped ions and electrons. First, we analyze, and derive exp…
Low frequency correlated charge noise measurements across multiple energy transitions in a tantalum transmon
Daniel M. Tennant, Luis A. Martinez, Kristin M. Beck +5
Transmon qubits fabricated with tantalum metal have been shown to possess energy relaxation times greater than 300 s and, as such, present an attractive platform for high precis…
