Simple analytical flux-tuned iSWAP pulses for leakage suppression
Dimitrios Georgiadis, Boxi Li, Asier Galicia +3
Fast, high-fidelity two-qubit gates are a key requirement for fault-tolerant quantum computation. Tunable coupler architectures provide a flexible approach for implementing entangl…
Analytical blueprint for 99.999% fidelity X-gates on present superconducting hardware under strong driving
José Diogo Da Costa Jesus, Boxi Li, Yuan Gao +3
Achieving very fast gates that undercut the natural limits set by decoherence requires going into the strong driving limit. Realizing single-qubit control predicted beyond semi-cla…
Ultrafast Single Qubit Gates through Multi-Photon Transition Removal
Y. Gao, A. Galicia, J. D. Da Costa Jesus +12
One of the main enablers in quantum computing is having qubit control that is precise and fast. However, qubits typically have multilevel structures making them prone to unwanted t…
Performance-centric roadmap for building a superconducting quantum computer
R. Barends, F. K. Wilhelm
One of the outstanding challenges in contemporary science and technology is building a quantum computer that is useful in applications. By starting from an estimate of the algorith…
Dispersive Qubit Readout with Intrinsic Resonator Reset
M. Jerger, F. Motzoi, Y. Gao +9
A key challenge in quantum computing is speeding up measurement and initialization. Here, we experimentally demonstrate a dispersive measurement method for superconducting qubits t…
