Heterogeneously Integrated Squeezed-Light Generation and Detection on a Single Photonic Chip
Haoran Chen, Benjamin Westcott, Fatemehsadat Tabatabaei +10 more·Aug 13, 2026
Squeezed light underpins quantum-enhanced sensing and continuous-variable quantum information processing, and integrated photonics offers a route to producing it at scale. Universal to these applications are squeezed-light generation and measurement....
Ion trap on borosilicate substrate with integrated femtosecond-laser-written waveguide
Jakob Wahl, Alexander Zesar, Philipp Hurdax +9 more·Aug 13, 2026
We present an ion-trap platform on borosilicate glass with an integrated femtosecond-laser-written waveguide for on-chip light delivery. The optical layer is physically separated from the electrode substrate and bonded atop the trap, remaining compat...
Counter-examples for Tensorization Property of Strong Data Processing Inequality for Quantum Divergences
Yu Cao·Aug 13, 2026
The data processing inequality is a fundamental property that describes the loss of information through noisy channels. A more refined description is characterized by the strong data processing inequality (SDPI). In classical information theory, the ...
Enabling Ultra-Low-Power Always-On Feedforward Leakage Suppression Logic Circuits with FDSOI
Clément Choné, Leslie Xu, Filippo Quadri +5 more·Aug 13, 2026
The growing deployment of real-time applications on wearable and Internet of Things (IoT) edge devices has intensified the need for energy-efficient, high-performance systems that meet stringent timing and energy constraints. Events-driven architectu...
Mid-circuit ground-state cooling and ancilla readout in the $\textit{omg}$ architecture
Sean Brudney, Connor Burns, Gabriel J. Gregory +4 more·Aug 13, 2026
The trapped-ion optical-metastable-ground ($\textit{omg}$) architecture for quantum processors promises the full functionality of two-species experiments, including sympathetic cooling and non-destructive ancilla readout, without the corresponding ha...
Entanglement distribution and quantum storage of more than 8000 modes over a metropolitan network
Angelo Gelmini Rodriguez, Louis Nicolas, Théo Sanchez Mejia +6 more·Aug 13, 2026
Entanglement generation between telecommunication photons and matter is central to fibre-based quantum repeaters. Achieving practical communication rates requires multiplexing, which multimode quantum memories can provide. Rare-earth-ion ensembles of...
Witnessing the architecture of quantum circuits
Raphaël Mothe, Otfried Gühne·Aug 13, 2026
Determining whether a target unitary can be implemented within a prescribed quantum circuit architecture is a fundamental problem in quantum information, with direct implications for optimisation and compilation of quantum circuits, and hardware-effi...
Controlled dynamics of a multi-component discrete-time quantum walker
Vikash Mittal, Tomasz Sowiński·Aug 13, 2026
We investigate a discrete-time quantum walk of a three-component quantum particle on a one-dimensional lattice. As coin operators, we employ parameterized rotations generated by the Gell-Mann matrices, which enable systematic tuning of the couplings ...
ProbSplat: Efficient Probabilistic Hardware for Gaussian Splatting in 3D Scene Reconstruction
Siddarth Gottumukkula, M P Samartha, Vedant Pahariya +3 more·Aug 13, 2026
This paper presents ProbSplat, a Compute-in-Memory (CIM)-inspired architecture based on programmable and energy efficient floating-gate inverter columns for probabilistic computing. Improving upon our prior work, ProbSplat programs and stores both me...
Classical Simulation and Design Frontiers for IBM's Doped Clifford Sampling Experiment
Hidetaka Manabe, Hanfeng Gu, Feng Pan·Aug 13, 2026
We classically simulate the IBM doped Clifford random circuit sampling experiment, comprising $70$ qubits, $70$ entangling layers, and $468$ inserted $T$ gates. A deterministic temporal-boundary tensor network contraction approach is specifically des...
Controlling quantum transport by measurement-rate modulation
Jesús Casado-Pascual, Luis Octavio Castaños-Cervantes·Aug 13, 2026
Temporal modulation of the measurement rate provides a powerful mechanism for controlling open-system dynamics through measurement backaction. We demonstrate this mechanism in a minimal exactly solvable model of a continuously monitored quantum parti...
Formal Verification of Quantum Ancilla Safety
Jiqi Li, Jingyi Mei, Wang Fang +1 more·Aug 13, 2026
Ensuring ancilla safety is a critical correctness requirement for quantum compilation, since ancilla qubits are routinely introduced to implement complex operations with fewer gates and reduced depth. However, formally verifying this property is comp...
Time-resolved correlation engineering in DLCZ Raman photon sources
Jiun-Shiuan Shiu, Chang-Wei Lin, Chi-Ming Yang +2 more·Aug 13, 2026
Memory-assisted quantum networks require photon sources with controllable temporal and correlation properties. The Duan-Lukin-Cirac-Zoller (DLCZ) protocol provides a platform based on spontaneous Raman scattering in atomic ensembles, but a unified pr...
Robust controlled-Z gate for Rydberg atoms based on level-crossing-free echoing rapid adiabatic passage
Yichi Zhang, Zhenqi Bai, Xu Zhao +3 more·Aug 13, 2026
We propose a controlled-Z gate scheme for Rydberg atoms based on level-crossing-free echoing rapid adiabatic population transfer. We design antisymmetric Rabi frequency pulses and symmetric detuning pulses, enabling the system to completely avoid lev...
Quantifying nonclassicality in qubit systems via positive operator-valued measures
Abdul Sattar Khan, Mehdi Abdi·Aug 13, 2026
We introduce an operational measure of nonclassicality for qubit systems based on the violation of Kolmogorov consistency conditions in sequential measurements. In contrast to previous work by Milz et al.~\cite{Milz-2020}, who characterized classical...
Local and quasilocal conservation laws of three-state IRF cellular automata and their quantum deformations
Tomaž Prosen·Aug 13, 2026
Using patch-matrix-product methods, we study two reversible three-state interaction-round-a-face cellular automata introduced by Klobas and Prosen [J. Phys. A 55, 094003 (2022)] - the species-preserving and species-flipping rules - and a coherent qua...
BoardroomAI: Dependency-Aware Human-Steerable Multi-Agent Deliberation through Evolving Decision Graphs
Sanjeev Manivannan·Aug 13, 2026
Organizational decisions are co-created while evidence, constraints, and human priorities continue to evolve. In conventional transcript-based multi-agent systems, humans typically provide an initial problem, agents deliberate internally, and the sys...
