Hardware-Efficient Erasure Qubits With Superconducting Transmon Qutrits
Bao-Jie Liu, Ying-Ying Wang, Yu-Xin Wang +3
Quantum error correction using erasure qubits offers higher fault-tolerant thresholds and improved scaling by converting dominant physical errors into detectable erasures. In super…

Observation of discrete charge states of a coherent two-level system in a superconducting qubit
Bao-Jie Liu, Ying-Ying Wang, Tal Sheffer +1
We report observations of discrete charge states of a coherent dielectric two-level system (TLS) that is strongly coupled to an offset-charge-sensitive superconducting transmon qub…

Dispersive Non-reciprocity between a Qubit and a Cavity
Ying-Ying Wang, Yu-Xin Wang, Sean van Geldern +3
The dispersive interaction between a qubit and a cavity is ubiquitous in circuit and cavity quantum electrodynamics. It describes the frequency shift of one quantum mode in respons…
