Four modes of optical parametric operation for squeezed state generation
, 2003 We report a versatile instrument, based on a monolithic optical parametric amplifier, which reliably generates four different types of squeezed light.

Advanced Science, EarlyView.An injectable and self‐reinforcing RSF‐based piezoelectric hydrogel conforms to irregular bone defects and progressively strengthens in situ, overcoming the trade‐off between injectability and mechanical stability. Mechanical loading generates bioelectrical cues that promote P300‐mediated H3K9 acetylation and upregulate PTH1R expression, thereby ...

Rapid phase estimation of cavity squeezed states via optimal parametric control
Journal of Physics CommunicationsIdeally, the characterization of non-classical states requires measurements on timescales much shorter than the system’s decoherence time. However, in quantum cavity electrodynamics, photon loss rates are often comparable to measurement rates, which ...

Squeezed-state approach to the E-e Jahn-Teller system
, 1990 We propose a new variational ground state, the displaced-squeezed-state, for the linear E-e Jahn-Teller system. The variational ground-state energy and the corresponding Ham's reduction factor are calculated and the results are compared with those of ...

Experiments on Nonlocal Fluid‐Flow Metamaterials
Advanced Science, EarlyView.A nonlocal fluid‐flow metamaterial composed of standard microfluidic tubes and connectors is designed. Hence, the current of the system at one position depends on the gradient of fluid flow at many other positions, leading to unusual alternating backward and forward laminar flows of water.

Advanced Science, EarlyView.Sarcopenia has emerged as a major health challenge in the aging population. Developing a sustained‐release system for whey protein may enhance its effectiveness in mitigating sarcopenia. Herein, a novel “single‐protein particle encapsulation” (SPPE) system is developed to protect whey protein and control its release.

The entanglement evolution of the quantum optical systems
Journal of Physics CommunicationsIn this paper, we apply the Thermofield Dynamics (TFD) method to transform a quantum optical master equation into a Schrödinger-like equation for an arbitrary initial condition, making it a preferred approach for solving open quantum system problems ...

Robust adaptive quantum phase estimation
New Journal of Physics, 2015 Quantum parameter estimation is central to many fields such as quantum computation, communications and metrology. Optimal estimation theory has been instrumental in achieving the best accuracy in quantum parameter estimation, which is possible when we ...

Heisenberg-Limited Noisy Atomic Clock Using a Hybrid Coherent and Squeezed State Protocol
, 2020 We propose a hybrid quantum-classical atomic clock where the interrogation of atoms prepared in a spin-coherent (or weakly squeezed) state is used to feed back one or more highly spin-squeezed atomic states toward their optimal phase-sensitivity point ...
