Hybrid SU(1,1) interferometry in optomechanics
Chao Meng, Emil Zeuthen, Polina R. Sharapova
In non-degenerate SU(1,1) interferometers, beam splitters are replaced by two-mode squeezers, enabling sub-shot-noise sensitivity without input squeezing and robustness to detectio…
Generation of True Quantum Random Numbers with On-Demand Probability Distributions via Single-Photon Quantum Walks
Chaoying Meng, Miao Cai, Yufang Yang +7
Random numbers are at the heart of diverse fields, ranging from simulations of stochastic processes to classical and quantum cryptography. The requirement for true randomness in th…
Enhancement of mechanical squeezing via feedback control
Chao Meng, Warwick P. Bowen
We explore the generation of nonclassical mechanical states by combining continuous position measurement and feedback control. We find that feedback-induced spring softening can gr…
Measurement-based preparation of non-Markovian and multimode mechanical states
Chao Meng, George A. Brawley, Soroush Khademi +3
Nanomechanical resonators are a key tool for future quantum technologies such as quantum force sensors and interfaces, and for studies of macroscopic quantum physics. The ability t…
Mechanical squeezing via fast continuous measurement
Chao Meng, George A. Brawley, James S. Bennett +2
We revisit quantum state preparation of an oscillator by continuous linear position measurement. Quite general analytical expressions are derived for the conditioned state of the o…
Propagation and imaging of mechanical waves in a highly-stressed single-mode phononic waveguide
Erick Romero, Rachpon Kalra, Nicolas P. Mauranyapin +3
We demonstrate a single-mode phononic waveguide that enables robust propagation of mechanical waves. The waveguide is a highly-stressed silicon nitride membrane that supports the p…
Generating Giant and Tunable Nonlinearity in a Macroscopic Mechanical Resonator from Chemical Bonding Force
Pu Huang, Jingwei Zhou, Liang Zhang +8
Nonlinearity in macroscopic mechanical system plays a crucial role in a wide variety of applications, including signal transduction and processing, synchronization, and building lo…
