Tunable Coupler for Mediating Interactions between a Two-Level System and a Waveguide from a Decoupled State to the Ultra-Strong Coupling Regime
N. Janzen, X. Dai, S. Ren +2
Two-level systems (TLS) coupled to waveguides are a fundamental paradigm for light-matter interactions and quantum networks. We introduce and experimentally demonstrate a method to…
Characterization of Control in a Superconducting Qutrit Using Randomized Benchmarking
M. Kononenko, M. A. Yurtalan, S. Ren +3
We characterize control of a qutrit implemented in the lowest three energy levels of a capacitively-shunted flux-biased superconducting circuit. Randomized benchmarking over the qu…
Characterization of multi-level dynamics and decoherence in a high-anharmonicity capacitively shunted flux circuit
M. A. Yurtalan, J. Shi, G. J. K. Flatt +1
We present the design and characterization of a three-Josephson-junction superconducting loop circuit with three large shunt capacitors. Used as a qubit, the circuit shows long ene…
Implementation of a Walsh-Hadamard gate in a superconducting qutrit
M. A. Yurtalan, J. Shi, M. Kononenko +2
We have implemented a Walsh-Hadamard gate, which performs a quantum Fourier transform, in a superconducting qutrit. The qutrit is encoded in the lowest three energy levels of a cap…
