Broadband frequency conversion via adiabatically tapered waveguide in photonic integrated circuits
Xiao Xiong, Chang-Ling Zou, Xiang Guo +3
We propose to use the integrated aluminum nitride waveguide with engineered width variation to achieve optical frequency conversion based on nonlinear effect on a photoni…
Cat codes with optimal decoherence suppression for a lossy bosonic channel
Linshu Li, Chang-ling Zou, Victor V. Albert +3
We investigate cat codes that can correct multiple excitation losses and identify two types of logical errors: bit-flip errors due to excessive excitation loss and dephasing errors…
Noise-free quantum optical frequency shifting driven by mechanics
Linran Fan, Chang-Ling Zou, Menno Poot +4
The ability to manipulate single photons is of critical importance for fundamental quantum optics studies and practical implementations of quantum communications. While extraordina…
Chiral Symmetry Breaking in Micro-Ring Optical Cavity By Engineered Dissipation
Fang-Jie Shu, Chang-Ling Zou, Xu-Bo Zou +1
We propose a method to break the chiral symmetry of light in traveling wave resonators by coupling the optical modes to a lossy channel. Through the engineered dissipation, an indi…
Multimode Strong Coupling in Superconducting Cavity Piezo-electromechanics
Xu Han, Chang-Ling Zou, Hong X. Tang
High frequency mechanical resonators subjected to low thermal phonon occupancy are easier to be prepared to the ground state by direct cryogenic cooling. Their extreme stiffness, h…

Quantum photonic chips, which integrate quantum light sources alongside active and passive optical elements, as well as single photon detectors, show great potential for photonic q…
Strongly-coupled nanotube electromechanical resonators
Guang-Wei Deng, Dong Zhu, Xin-He Wang +11
Coupling an electromechanical resonator with carbon-nanotube quantum dots is a significant method to control both the electronic charge and the spin quantum states. By exploiting a…
Mechanical bound state in the continuum for optomechanical microresonators
Yuan Chen, Zhen Shen, Xiao Xiong +3
Clamping loss limits the quality factor of mechanical mode in the optomechanical resonators supported with the supporting stem. Using the mechanical bound state in the continuum, w…
