Kerr-enhanced amplification of three-wave mixing and emergent masing regimes
Ragheed Alhyder, Rishabh Sahu, Johannes M. Fink +2 more·Jan 21, 2026
Integrated optical microresonators exploiting either second-order ($χ^{(2)}$) or third-order ($χ^{(3)}$) nonlinearities have become key platforms for frequency conversion, low-noise microwave photonics, and quantum entanglement generation. Here, we p...
Information transport and transport-induced entanglement in open fermion chains
Andrea Nava, Claudia Artiaco, Yuval Gefen +4 more·Jan 20, 2026
Understanding the entanglement dynamics in quantum many-body systems under steady-state transport conditions is an actively pursued challenging topic. Hydrodynamic equations, akin to transport equations for charge or heat, would be of great interest ...
Optimal Construction of Two-Qubit Gates using the Symmetries of B Gate Equivalence Class
M. Karthick Selvan, S. Balakrishnan·Jan 20, 2026
Two applications of gates from the B gate equivalence class can generate all two-qubit gates. This local equivalence class is invariant under the mirror (multiplication with the SWAP gate) operation, inverse (Hermitian conjugate) operation, and the c...
Ultra Compact low cost two mode squeezed light source
Shahar Monsa, Shmuel Sternklar, Eliran Talker·Jan 20, 2026
Quantum-correlated states of light, such as squeezed states, constitute a fundamental resource for quantum technologies, enabling enhanced performance in quantum metrology, quantum information processing, and quantum communications. The practical dep...
Bright Heralded Single-Photon Superradiance in a High-Density Thin Vapor Cell
Heewoo Kim, Bojeong Seo, Han Seb Moon·Jan 20, 2026
Superradiance is a hallmark of cooperative quantum emission, where radiative decay is collectively enhanced by coherence among emitters. Here, extending superradiant effects to photon pair generation from multi-level atoms, two-photon process offers ...
Confinement-Tunable Synthetic Gauge Fields and Floquet Topological Phenomena in a Driven Quantum Wire Qubit
Feulefack Ornela Claire, Dongmo Tedo Lynsia Saychele, Danga Jeremie Edmond +6 more·Jan 20, 2026
Theoretical analysis demonstrates that a spin qubit in a parabolic quantum wire, when driven by a bichromatic field, exhibits a confinement-tunable synthetic gauge field leading to novel Floquet topological phenomena. The underlying mechanism for top...
Quantum Entanglement Geometry on Severi-Brauer Schemes: Subsystem Reductions of Azumaya Algebras
Kazuki Ikeda·Jan 20, 2026
Quantum entanglement is a defining signature and resource of quantum theory, but its standard definition presupposes a globally fixed decomposition into subsystems. We develop a geometric framework that detects when such a decomposition cannot be glo...
On-Chip Generation of Co-Polarized and Spectrally Separable Photon Pairs
Xiaojie Wang, Lin Zhou, Yue Li +10 more·Jan 20, 2026
On-chip generation of high-purity single photons is essential for scalable photonic quantum technologies. Spontaneous parametric down-conversion (SPDC) is widely used to generate photon pairs for heralded single-photon sources, but intrinsic spectral...
Generative Adversarial Networks for Resource State Generation
Shahbaz Shaik, Sourav Chatterjee, Sayantan Pramanik +1 more·Jan 20, 2026
We introduce a physics-informed Generative Adversarial Network framework that recasts quantum resource-state generation as an inverse-design task. By embedding task-specific utility functions into training, the model learns to generate valid two-qubi...
