Fast Bosonic Control via Multiphoton Qubit-Oscillator Interactions
Noah Gorgichuk, Mohammad Ayyash, Matteo Mariantoni +1
We present a protocol for preparing oscillator states with -fold rotational symmetry, which include many logical codewords for bosonic quantum error correction codes. The protoc…
A Scalable Superconducting Circuit Framework for Emulating Physics in Hyperbolic Space
Xicheng Xu, Ahmed Adel Mahmoud, Noah Gorgichuk +3
Theoretical studies and experiments in the last six years have revealed the potential for novel behaviours and functionalities in device physics through the synthetic engineering o…
Driven Multiphoton Qubit-Resonator Interactions
Mohammad Ayyash, Xicheng Xu, Sahel Ashhab +1
We develop a general theory for multiphoton qubit-resonator interactions enhanced by a qubit drive. The interactions generate qubit-conditional operations in the resonator when the…
Purity benchmarking study of error coherence in a single Xmon qubit
Auda Zhu, Jérémy H. Béjanin, Xicheng Xu +1
In this study, we employ purity benchmarking (PB) to explore the dynamics of gate noise in a superconducting qubit system. Over 1110 hours of observations on an Xmon qubit, we simu…
