Contextuality Derived from Minimal Decision Dynamics: Quantum Tug-of-War Decision Making

Song-Ju Kim·Jan 15, 2026

Decision making often exhibits context dependence that challenges classical probability theory. While quantum cognition has successfully modeled such phenomena, it remains unclear whether quantum probability is merely a convenient assumption or a nec...

Reentrant topological phases and entanglement scalings in moiré-modulated extended Su-Schrieffer-Heeger Model

Guo-Qing Zhang, L. F. Quezada, Shi-Hai Dong·Jan 15, 2026

Recent studies of moiré physics have unveiled a wealth of opportunities for significantly advancing the field of quantum phase transitions. However, properties of reentrant phase transitions driven by moiré strength are poorly understood. Here, we in...

Light-induced Magnetization by Quantum Geometry

Hiroki Yoshida, Takehito Yokoyama·Jan 14, 2026

We propose a mechanism for the inverse Faraday and the inverse Cotton--Mouton effects arising from quantum geometry, characterized by the quantum metric quadrupole and the weighted quantum metric. Within a semiclassical framework based on the Boltzma...

Non-invertible circuit complexity from fusion operations

Saskia Demulder·Jan 14, 2026

Modern understanding of symmetry in quantum field theory includes both invertible and non-invertible operations. Motivated by this, we extend Nielsen's geometric approach to quantum circuit complexity to incorporate non-invertible gates. These arise ...

A measurement-based protocol for the generation of delocalised quantum states of a mechanical system

Matteo Bordin·Jan 14, 2026

Non-Gaussian mechanical states are a key resource for quantum-enhanced sensing and tests of macroscopic quantum physics. We propose a measurement-based protocol to herald delocalized, nonclassical states of a mechanical oscillator in cavity optomecha...

Relaxation Process During Complex Time Evolution In Two-Dimensional Integrable and Chaotic CFTs

Chen Bai, Weibo Mao, Masahiro Nozaki +2 more·Jan 14, 2026

We investigate the complex time evolution of a vacuum state with the insertion of a local primary operator in two-dimensional conformal field theories (2d CFTs). This complex time evolution can be considered as a composite process constructed from Lo...

Mechanistic principles of exciton-polariton relaxation

Ian Haines, Arshath Manjalingal, Logan Blackham +2 more·Jan 14, 2026

Exciton-polaritons are light-matter hybrid quasi-particles that have emerged as a flexible platform for developing quantum technologies and engineering material properties. However, the fundamental mechanistic principles that govern their dynamics an...

Quantifying the Relationship Between Strain and Bandgap in Thin Ga$_2$Se$_2$

Lottie L. Murray, Eric Herrmann, Igor Evangelista +3 more·Jan 13, 2026

We present a rigorous analysis that combines theory, simulation, and experimental measurements to quantify the relationship between strain and bandgap in two dimensional gallium selenide (Ga$_2$Se$_2$). Experimentally, we transfer thin Ga$_2$Se$_2$ f...

Breaking the Orthogonality Barrier in Quantum LDPC Codes

Kenta Kasai·Jan 13, 2026

Classical low-density parity-check (LDPC) codes are a widely deployed and well-established technology, forming the backbone of modern communication and storage systems. It is well known that, in this classical setting, increasing the girth of the Tan...

Local Magnetometry from Measurement-Induced Dissipation

Rishith Reddy, Parveen Kumar, Ankur Das·Jan 13, 2026

Magnetic phases are commonly identified through macroscopic magnetization, yet many ordered states, including antiferromagnets and altermagnets, possess a vanishing net moment despite distinct local spin structure. We show that such an order can be a...

Attosecond quantum optics

Mohamed Sennary, Javier Rivera-Dean, Yihe Wange +2 more·Jan 13, 2026

Modern quantum optics primarily operates in the quasistationary regime, isolated from the intrinsic timescales of ultrafast optical fields. Pushing these boundaries into the femtosecond and attosecond domains is a critical frontier. Here, we generate...

Phase-sensitive superposition of quantum states

Xiaotong Wang, Shunlong Luo, Yue Zhang·Jan 13, 2026

Although the principle of superposition lies at the heart of quantum mechanics and is the root of almost all quantum phenomena such as coherence and entanglement, its quantification, except for that related to the resource theory of coherence and int...

Extending Qubit Coherence Time via Hybrid Dynamical Decoupling

Qi Yao, Jun Zhang, Wenxian Zhang +1 more·Jan 13, 2026

Dynamical decoupling (DD) and bath engineering are two parallel techniques employed to mitigate qubit decoherence resulting from their unavoidable coupling to the environment. Here, we present a hybrid DD approach that integrates pulsed DD with bath ...

Vacuum-dressed superconductivity in NbN observed in a high-$Q$ terahertz cavity

Hongjing Xu, Andrey Baydin, Qinyan Yi +8 more·Jan 13, 2026

Emerging theoretical frameworks suggest that physical properties of matter can be altered within an optical cavity by harnessing quantum vacuum electromagnetic fluctuations, even in the total absence of external driving fields. Among the most intrigu...

Chiroptical effect induced by gravitational waves

Haorong Wu, Xilong Fan·Jan 12, 2026

We propose the gravitational analog of the chiroptical effect for the first time, demonstrating that gravitational waves (GWs) can induce a reversal of photon chirality through the exchange of angular momentum, namely the spin-2-gravitation chiroptic...
