Quantum Nondemolition Measurement of a Nonclassical State of a Massive Object

Physical Review X, 2015
By coupling a macroscopic mechanical oscillator to two microwave cavities, we simultaneously prepare and monitor a nonclassical steady state of mechanical motion.

Experimental Investigation of the Effect of Dispersion on Squeezing Generation in a Synchronously Pumped Optical Parametric Oscillator

Advanced Quantum Technologies, Volume 9, Issue 9, September 2026.
Intracavity dispersion in a synchronously pumped optical parametric oscillator is expected to degrade multimode squeezing. Experiments show that squeezing remains unchanged over the explored group delay dispersion range because dispersion acts as a spectral filter during supermode generation, reducing the effective dispersion parameter and preserving ...

Ni–Cr Substitution in TiFe: An Integrated Experimental–Modeling Study of Phase Stability and Hydride Thermodynamics

Advanced Energy and Sustainability Research, Volume 7, Issue 8, August 2026.
Combined experimental and theoretical approaches reveal how Cr and Ni substitution in TiFe‐based alloys tune lattice expansion and hydride thermodynamics. While both elements increase hydride stability, they exert opposite effects on the entropy of hydrogen desorption, providing new insight into thermodynamic design of AB‐type hydrogen storage ...

Quantum backaction evading measurements of a silicon nitride membrane resonator

New Journal of Physics, 2022
Quantum backaction disturbs the measurement of the position of a mechanical oscillator by introducing additional fluctuations. In a quantum backaction measurement technique, the backaction can be evaded, although at the cost of losing part of the ...

Bulk-source-coupled CMOS quadrature oscillators

Electronics Letters, 2009
A quadrature oscillator based on a coupling between the bulk and the source of MOS transistors is proposed. Since the resonator load is not directly involved in the coupling process, the oscillation frequency is very close to the resonant frequency, hence a good phase noise characteristic. The developed theory matches very well to the simulations.
