Adaptive Phase Estimation with Squeezed Vacuum Approaching the Quantum Limit [PDF]

Quantum
Phase estimation plays a central role in communications, sensing, and information processing. Quantum correlated states, such as squeezed states, enable phase estimation beyond the shot-noise limit, and in principle approach the ultimate quantum limit in

Atomic‐Scale Light Coupling Control in Ultrathin Photonic Membranes

Advanced Functional Materials, EarlyView.
Ultrathin photonic nanomembranes provide atomic‐scale control over the coupling between incident light and high‐Q photonic modes, enabling angstrom‐level resonance tuning and strong field confinement. When integrated with TMD monolayers, they further yield enhanced light–matter interactions, offering a versatile platform for advancing quantum photonics,

Quantum vacuum magneto-optics

Comptes Rendus. Physique, 2012
In this article we report on the recent experimental activities concerning the magneto-optics of quantum vacuum performed by our team based at the LNCMI of Toulouse. In particular, we will deal with quantum vacuum Cotton–Mouton and inverse Cotton–Mouton effects which have been predicted in the framework of Quantum electrodynamics.

Through Diamond Robust Surface Enhanced Raman Spectroscopy

Advanced Functional Materials, EarlyView.
Thin film diamond growth offers a unique opportunity for Surface Enhanced Raman Spectroscopy (SERS); the encapsulation of plasmonic nanostructures within a transparent, chemically stable, and physically robust coating. The diamond acts as both a window and protective layer, enabling illumination of the plasmonic nanostructures through the diamond ...

Theoretical Calculation of Vacuum Energy Density Based on the Fractal Quantum Gravity Theory

Reports in Advances of Physical Sciences
There has been a huge discrepancy between the vacuum energy density calculated based on the existing quantum theories and the observational values. The calculated vacuum energy density is about 120 orders of magnitude greater than its observational ...

The Rotating Quantum Vacuum

, 1996
We derive conditions for rotating particle detectors to respond in a variety of bounded spacetimes and compare the results with the folklore that particle detectors do not respond in the vacuum state appropriate to their motion. Applications involving possible violations of the second law of thermodynamics are briefly addressed.

Magnetic Force Microscopy Signatures of Higher‐Order Skyrmions and Antiskyrmions

Advanced Functional Materials, EarlyView.
Magnetic force microscopy operated under vacuum conditions enables the qualitative identification of higher‐order skyrmions and antiskyrmions in Co/Ni multilayers at room temperature. Distinct stray‐field contrast signatures arise from vertical Bloch lines and complex domain‐wall configurations.
