Gravitational Effects on Sagnac Interferometry

Published:Dec 30, 2025 19:19
1 min read
ArXiv

Analysis

This paper investigates the impact of gravitational waves on Sagnac interferometers, going beyond the standard Sagnac phase shift to identify a polarization rotation effect. This is significant because it provides a new way to detect and potentially characterize gravitational waves, especially for freely falling observers where the standard phase shift vanishes. The paper's focus on gravitational holonomy suggests a deeper connection between gravity and the geometry of the interferometer.
Reference

“The paper identifies an additional contribution originating from a relative rotation in the polarization vectors, formulating this effect as a gravitational holonomy associated to the internal Lorentz group.”

Robust Physical Encryption with Standard Photonic Components

Published:Dec 30, 2025 11:29
1 min read
ArXiv

Analysis

This paper presents a novel approach to physical encryption and unclonable object identification using standard, reconfigurable photonic components. The key innovation lies in leveraging spectral complexity generated by a Mach-Zehnder interferometer with dual ring resonators. This allows for the creation of large keyspaces and secure key distribution without relying on quantum technologies, making it potentially easier to integrate into existing telecommunication infrastructure. The focus on scalability and reconfigurability using thermo-optic elements is also significant.
Reference

“The paper demonstrates 'the generation of unclonable keys for one-time pad encryption which can be reconfigured on the fly by applying small voltages to on-chip thermo-optic elements.'”

    1 min read
    ArXiv

    Analysis

    This article likely discusses the application of Graph Neural Networks (GNNs) to simulate interferometers. GNNs are a type of neural network designed to process data represented as graphs, making them suitable for modeling complex systems like interferometers where components and their interactions can be represented as nodes and edges. The use of GNNs could potentially improve the efficiency and accuracy of interferometer simulations compared to traditional methods.
