Probing Quantum Anomalous Hall Transport Under Microwave Irradiation Using a Topological Circulator
Athul Ashok, Frank Jin, Nick Du +7
Edge magnetoplasmons (EMPs) provide a platform for probing chiral charge dynamics and nonreciprocal microwave transport in topological quantum materials. However, detecting small p…
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…
Circulators Based on Coupled Quantum Anomalous Hall Insulators and Resonators
Luis A. Martinez, Nick Du, Nicholas Materise +7
Integrated plasmonics is advancing rapidly, enabling a wide range of functionalities to be incorporated onto a single chip. Applications span information processing, computation, q…
Edge Magnetoplasmon Dispersion and Time-Resolved Plasmon Transport in a Quantum Anomalous Hall Insulator
Luis A. Martinez, Gang Qiu, Peng Deng +8
A quantum anomalous Hall (QAH) insulator breaks reciprocity by combining magnetic polarization and spin-orbit coupling to generate a unidirectional transmission of signals in the a…
Noise-specific beats in the higher-level Ramsey curves of a transmon qubit
L. A. Martinez, Z. Peng, D. Appelö +4
In the higher levels of superconducting transmon devices, and more generally charge sensitive devices, measurements made in the presence of low-frequency time-correlated $1…
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…
Improving Qubit Readout with Hidden Markov Models
Luis A. Martinez, Yaniv J. Rosen, Jonathan L. DuBois
We demonstrate the application of pattern recognition algorithms via hidden Markov models (HMM) for qubit readout. This scheme provides a state-path trajectory approach capable of…
High-fidelity software-defined quantum logic on a superconducting qudit
Xian Wu, S. L. Tomarken, N. Anders Petersson +3
Nearly all modern solid-state quantum processors approach quantum computation with a set of discrete qubit operations (gates) that can achieve universal quantum control with only a…
Simulating nonnative cubic interactions on noisy quantum machines
Yuan Shi, Alessandro R. Castelli, Xian Wu +8
As a milestone for general-purpose computing machines, we demonstrate that quantum processors can be programmed to efficiently simulate dynamics that are not native to the hardware…
