Magnetic-free optical mode degeneracy lifting in lithium niobate microring resonators

Xin-Biao Xu, Zheng-Xu Zhu, Yuan-Hao Yang +9

Breaking time-reversal symmetry in integrated photonics without magnetic fields remains a fundamental challenge. We demonstrate phonon-induced non-reciprocity through direct liftin…

All-optical control and multiplexed readout of multiple superconducting qubits

Xiaoxuan Pan, Chuanlong Ma, Jia-Qi Wang +12

Superconducting quantum circuits operate at millikelvin temperatures, typically requiring independent microwave cables for each qubit for connecting room-temperature control and re…

Giant-atom quantum acoustodynamics in hybrid superconducting-phononic integrated circuits

Lintao Xiao, Bo Zhang, Yu Zeng +11

We demonstrate a giant atom by coupling a superconducting transmon qubit to a lithium niobate phononic waveguide at two points separated by about 600 acoustic wavelengths, with a p…

Circuit Quantum Acoustodynamics in a Scalable Phononic Integrated Circuit Architecture

Weiting Wang, Lintao Xiao, Bo Zhang +11

Previous demonstrations of quantum acoustic systems have been limited to isolated devices, with limited capability to route phonons and interconnect multi-port acoustic elements fo…

Acoustically control of integrated optical microrings: from photonic molecule to Mobius strip

Zheng-Xu Zhu, Yuan-Hao Yang, Xin-Biao Xu +10

Microring resonators (MRRs) are fundamental building blocks of photonic integrated circuits, yet their dynamic reconfiguration has been limited to tuning refractive index or absorp…

Chip-integrated Brillouin Saser Gyroscope

Wen-Qi Duan, Ming-Xuan Zhao, Jia-Qi Wang +5

On-chip Brillouin laser gyroscopes harnessing opto-acoustic interaction are an emerging approach to detect rotation, due to their small footprint, excellent stability and low power…
