Fabless Quantum Chip Design and Commercial Production
Cai, Ling Qiao, Bin Yang +6 more·Jun 16, 2026
This paper proposes a fabless quantum-chip design and production architecture for superconducting quantum computing, centered on the SPICE-Q multiphysics simulation framework. The proposed ecosystem connects process-certified quantum PDKs, parameteri...
A Lindbladian for holographic Brownian motion
Daichi Takeda·Jun 16, 2026
We derive a Lindbladian description of holographic Brownian motion in the high-temperature regime. Starting from the influence functional for a trailing string endpoint, we identify the corresponding quantum master equation and prove that it is compl...
Twin-beam advantage in quantum LiDAR under correlated noise
Valeria Cimini·Jun 16, 2026
Quantum light promises improved precision in optical remote sensing, but its practical advantage depends critically on whether nonclassical resources remain useful under realistic noise and experimentally accessible detection. This question becomes e...
SPICE-Q and Large-Scale Quantum Chip Production
Cai, Ling Qiao, Bin Yang +7 more·Jun 16, 2026
We propose SPICE-Q, a SPICE-inspired design-technology co-optimization framework for superconducting quantum processors. Rather than replacing tools such as HFSS, Qiskit Metal, pyEPR, SQcircuit, SQuADDS, scqubits, or QuTiP, SPICE-Q aims to connect th...
Quantum Chip Paradigm Framework
Cai, Ling Qiao, Bin Yang +7 more·Jun 16, 2026
Quantum Electronic Design Automation (Q-EDA) is emerging as quantum chips move from laboratory prototypes to scalable engineering systems. This paper argues that superconducting quantum chip design is approaching a "SPICE moment" similar to early cla...
Demultiplexing Generalized Information via Quantum Transmission Lines
Soham Sau, Anna Jenčová, Tamal Guha·Jun 16, 2026
Demultiplexers are the fundamental primitives of network architecture, enabling perfect routing of an input classical signal to a designated one, among multiple output ports. Quantum transmission lines, having access to the quantum systems directly, ...
Frequency upconversion of infrared signals via molecular cavity optomechanical systems with gain
Shu-Xian Quan, Fen Zou, Yong Li·Jun 16, 2026
Molecular cavity optomechanical systems have recently emerged as a promising platform for enhancing infrared detection sensitivity, owing to their ability to up-convert low-frequency infrared (IR) photons to visible frequency range. Generally, under ...
Experimental Characterization and Modeling of Measurement-Induced State-Transitions in a Fluxonium Superconducting Qubit
Martijn F. S. Zwanenburg, Jinlun Hu, Eugene Y. Huang +3 more·Jun 16, 2026
Superconducting qubits are most often measured using dispersive readout, which, ideally, implements a projective quantum non-demolition (QND) measurement. While a larger readout drive can increase the signal and, thus, reduce discrimination errors in...
Split-Head Quantum Generative Adversarial Network for Crystalline Material Discovery
Huan-Ming Chang, Jen-Yu Chang, Tsung-Wei Huang +1 more·Jun 16, 2026
The discovery of novel crystalline materials is a critical challenge in computational materials science, often limited by the spatial representation limitations and mode collapse typical of classical generative models. Traditionally, developing Quant...
Creating squeezed and non-classical collective motional many-body states through stroboscopic Rydberg dressing
Roman Wußler, Chris Nill, Sylvain de Léséleuc +2 more·Jun 16, 2026
Realizing conditional quantum operations, e.g., quantum gates, for quantum computing and simulation requires controlled interactions between particles. Often, these interactions depend on the interparticle distance, and accordingly, an uncertainty of...
Engineering entanglement and transport in interacting quantum walks with tailored potentials
Gaia Forghieri, Matteo G. A. Paris·Jun 16, 2026
Controlling the interplay between particle propagation and quantum correlation generation is a central challenge in quantum transport. Here, we investigate two distinguishable continuous-time quantum walkers evolving on parallel one-dimensional latti...
Quantum Routers: A Switching-Fabric Framework for Quantum-Native Forwarding
Jessica Illiano, Caterina De Risi, Angela Sara Cacciapuoti +1 more·Jun 16, 2026
Forwarding in quantum networks cannot be realized by directly transposing classical switching fabrics, since the no-cloning theorem and the quantum measurement postulate constrain the direct relay of quantum information while ruling out copy-based bu...
Cavity method for permutation models on Cayley trees
Masayuki Ohzeki·Jun 16, 2026
Motivated by permutation statistical models arising in random tensor networks, we study permutation models on a Cayley tree whose variables take values in the symmetric group $\Sn$. The pair interaction is assumed to depend only on the cycle type of ...
Dimension-Free Approximate Tensorization of Quantum Hypercontractivity for Qudit Depolarizing Semigroups
Yangjing Dong, Li Gao, Fengning Ou +2 more·Jun 16, 2026
We prove approximate tensorization for hypercontractivity and logarithmic-Sobolev constants for a class of reversible quantum Markov semigroups satisfying the positive off-diagonal scaling (PODS) condition. This class includes qubit examples and gene...
Optimizing bias-tailored quantum error correction beyond code-capacity noise
César Benito, I. Jesán Velázquez-Reséndiz, Alejandro Bermudez·Jun 16, 2026
We find that the substantial advantages predicted for bias-tailored quantum error correction (QEC) under code-capacity noise are strongly reduced once realistic syndrome extraction and circuit-level noise models are considered. We start by comparing ...
Coherent Control of an Embedded Bound State Without a Spectral Gap
Yue Chang·Jun 16, 2026
Bound states in the continuum (BICs) can confine photonic excitations in open systems without conventional cavities or band gaps, making them natural candidates for long-lived quantum storage and single-photon control. Their use is limited, however, ...
From Period Finding to Lattice Sampling: Experimental Insights into Shor's and Regev's Factoring Algorithms
Daniela Falcó, Arturo Rodríguez, Guillermo Rivas +1 more·Jun 16, 2026
Quantum algorithms for integer factorization represent one of the most prominent applications of quantum computation, with far-reaching implications for modern cryptography. While Shor's algorithm provides a polynomial-time solution in the ideal quan...
Quantum mechanics in configuration space in context
Arwa Bukhari, Margherita Moro, Max Davies +2 more·Jun 16, 2026
To enhance the way in which wave-particle duality is implemented in the modelling of quantum mechanical systems, Bukhari et al. [New J. Phys. 27, 084501 (2025)] recently introduced an alternative approach to quantum mechanics, namely quantum mechanic...
Quantum Computing Algebra (QCA), the theory and implementation
Jaroslav Hrdina, Dietmar Hildenbrand, Oliver Rettig·Jun 16, 2026
We present a real geometric algebra framework designed for the direct translation of the Dirac formalism into geometric algebra representations. Unlike previous approaches based on positive-definite signatures, QCA employs a split-signature construct...
Photon anti-bunching in high harmonic generation
Philipp Stammer, Javier Rivera-Dean, Maciej Lewenstein·Jun 16, 2026
Photon anti-bunching is the direct evidence for the existence of photons without having a classical counterpart. Unlike bunching of photons, which can have a semi-classical description, the effect of photon anti-bunching can only be understood with q...
