TLS Dynamics in a Superconducting Qubit Due to Background Ionizing Radiation
Ted Thorbeck, Andrew Eddins, Isaac Lauer +2
Superconducting qubit lifetimes must be both long and stable to provide an adequate foundation for quantum computing. This stability is imperiled by two-level systems (TLSs), curre…
Multi-qubit gates protected by adiabaticity and dynamical decoupling applicable to donor qubits in silicon
Wayne M. Witzel, Inès Montaño, Richard P. Muller +1
We present a strategy for producing multi-qubit gates that promise high fidelity with minimal tuning requirements. Our strategy combines gap protection from the adiabatic theorem w…
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…
Implications of Electronics Constraints for Solid-State Quantum Error Correction and Quantum Circuit Failure Probability
James E. Levy, Malcolm S. Carroll, Anand Ganti +6
In this paper we present the impact of classical electronics constraints on a solid-state quantum dot logical qubit architecture. Constraints due to routing density, bandwidth allo…
Optimized pulses for the control of uncertain qubits
Matthew D. Grace, Jason Dominy, Wayne M. Witzel +1
Constructing high-fidelity control fields that are robust to control, system, and/or surrounding environment uncertainties is a crucial objective for quantum information processing…
The impact of classical electronics constraints on a solid-state logical qubit memory
James E. Levy, Anand Ganti, Cynthia A. Phillips +5
We describe a fault-tolerant memory for an error-corrected logical qubit based on silicon double quantum dot physical qubits. Our design accounts for constraints imposed by support…
