Integrated emitters with CMOS-compatible tuning for large scale quantum SiN photonic circuits
J. Witte, A. Shadmani, Zhe Liu +10 more·Nov 26, 2025
Next-generation scalable quantum photonic technologies operating at the single photon level rely on bringing together optimized quantum building blocks with minimal optical coupling losses. Achieving this necessitates the heterogeneous integration of...
Many-Body Entanglement in Solid-State Emitters
Emma Daggett, Christian M. Lange, Bennet Windt +23 more·Nov 25, 2025
The preparation and control of quantum states lie at the heart of quantum information science (QIS). Recent advances in solid-state quantum emitters (QEs) and nanophotonics have transformed the landscape of quantum photonic technologies, enabling sca...
Nonreciprocal quantum information processing with superconducting diodes in circuit quantum electrodynamics
Nicolas Dirnegger, Prineha Narang, Arpit Arora·Nov 25, 2025
Introducing new components and functionalities into quantum devices is critical in advancing state-of-the-art hardware. Here, we propose superconducting diodes (SDs) as a coherent nonreciprocal element in circuit quantum electrodynamics (cQED) archit...
Routing in Non-Isotonic Quantum Networks
Maxwell Tang, Garrett Hinkley, Kenneth Goodenough +2 more·Nov 25, 2025
Optimal routing in quantum-repeater networks requires finding the best path that connects a pair of end nodes. Most previous work on routing in quantum networks assumes utility functions that are isotonic, meaning that the ordering of two paths does ...
Plug-n-Play Three Pulse Twin Field QKD
Anagha Gayathri, Aryan Bhardwaj, Nilesh Sharma +3 more·Nov 25, 2025
We present the experimental implementation of a three-time-bin phase-encoded Twin-Field Quantum Key Distribution (TF-QKD) protocol using a Sagnac-based star-topology plug-and-play architecture. The proposed encoding method leverages the relative phas...
Generation of Ultrahigh Anomalous Hall Conductivities via Optimally Prepared Topological Floquet States
Andrew Cupo, Hai-Ping Cheng, Chandrasekhar Ramanathan +1 more·Nov 25, 2025
Ultrafast quantum matter experiments have validated predictions from Floquet theory - notably, the dynamical modification of the electronic band structure and the light-induced anomalous Hall effect, via monotonic modulation of the driving amplitude....
Entropy Flow and Exceptional-Point Structure in Two-Mode Squeezed-Bath Dynamics
Eric R. Bittner·Nov 24, 2025
Squeezed reservoirs provide a powerful means of engineering nonclassical noise and controlling irreversible dynamics in open quantum systems. Here we develop a comprehensive analysis of two coupled harmonic oscillators driven by independent squeezed ...
Modelling and experimental verification of photoelectrical response of NV diamond spin centres
Josef Soucek, Michael Petrov, Michal Gulka +2 more·Nov 24, 2025
We report on a mathematical model of the photoelectric response of NV colour centres in diamond, that can be employed for sensing and quantum science information applications. Although the model applies to NV centre in diamond, it can be applied with...
Attosecond-resolved quantum fluctuations of light and matter
Matan Even Tzur, Chen Mor, Noa Yaffe +10 more·Nov 23, 2025
Until recently, attosecond optical spectroscopy and quantum optics evolved along non-overlapping directions. In attosecond science, attosecond pulses have been regarded as classical waves, applied to probe electron dynamics on their natural time scal...
Entanglement Generation via Hamiltonian Dynamics Having Limited Resources
Moein Naseri·Nov 22, 2025
We investigate the fundamental limits of entanglement generation under bipartite Hamiltonian dynamics when only finite physical resources-specifically, bounded energy variance-are available. Using the relative entropy of entanglement, we derive a clo...

Amin Masoumi, M. Korkali·Nov 21, 2025
Dynamic security control (DSC) is considered a pivotal step for the future power grid, which is increasingly penetrated by inverter-based resources. However, the efficiency of such practices, whether governed by automatic generation control or virtua...

Analytical Fock Representation of Two-Mode Squeezing for Quantum Interference
Xuemei Gu, Carlos Ruiz-Gonzalez, Mario Krenn·Nov 20, 2025
Two-mode squeezing is central to entangled-photon generation and nonlinear interferometry, yet standard perturbative low-gain treatments and Gaussian formalisms can obscure the interference of photon-number amplitudes, especially in nonlinear interfe...
