Anyonic exchange in the time domain is tied to Luttinger type scaling
Aleksander Latyshev, Ines Safi·Oct 23, 2025
We consider Fractional Quantum Hall (FQH) edges with a spatially local Quantum Point Contact (QPC). Within the Unified Nonequilibrium Perturbative (UNEP) framework, without assumptions on the underlying Hamiltonian $H_{0}$ for the edges, we search fo...
Measuring weak microwave signals via current-biased Josephson Junctions II: Arriving at single-photon detection sensitivity
Y. Q. Chai, M. Y. Wang, S. N. Wang +2 more·Oct 23, 2025
It is well known that the current-biased Josephson junction (CBJJ) can serve as a Josephson threshold detector (JTD) for the sensitive detection of weak microwave signals. Based on the recent work (PRB {\bf 111}, 024501 (2025)) on the detection sensi...
Phenomenological Noise Models and Optimal Thresholds of the 3D Toric Code
Ji-Ze Xu, Yin Zhong, Miguel A. Martin-Delgado +2 more·Oct 23, 2025
Three-dimensional (3D) topological codes offer the advantage of supporting fault-tolerant implementations of non-Clifford gates, yet their performance against realistic noise remains largely unexplored. In this work, we focus on the paradigmatic 3D t...
Mitigating Coherent Errors through a Decoherence-Resistant Variational Framework employing Stabilizer State
Giovanni Di Bartolomeo, Giulio Crognaletti, Angelo Bassi +1 more·Oct 23, 2025
Stabilizer states are a central resource in quantum information processing, underpinning a wide range of applications. While they can be efficiently generated via Clifford circuits, the presence of coherent errors, such as small-angle miscalibrations...
Restoring Quantum Superiority of Noisy Quantum Illumination
Wei Wu, Jun-Hong An·Oct 23, 2025
Quantum illumination uses quantum entanglement as a resource to enable higher-resolution detection of low-reflectivity targets than is possible with classical techniques. This revolutionary technology could transform modern radar. However, it is wide...
Electronically-controlled one- and two-qubit gates for transmon quasicharge qubits
Nicholas M. Christopher, Deniz E. Stiegemann, Abhijeet Alase +1 more·Oct 23, 2025
Superconducting protected qubits aim to achieve sufficiently low error rates so as to allow realization of error-corrected, utility-scale quantum computers. A recent proposal encodes a protected qubit in the quasicharge degree of freedom of the conve...
Isotropic Noise in Stochastic and Quantum Convex Optimization
Annie Marsden, Liam O'Carroll, Aaron Sidford +1 more·Oct 23, 2025
We consider the problem of minimizing a $d$-dimensional Lipschitz convex function using a stochastic gradient oracle. We introduce and motivate a setting where the noise of the stochastic gradient is isotropic in that it is bounded in every direction...
Reduced State Embedding for Error Correction in Quantum Cryptography
Amit Kam, Kfir Sulimany, Shai Tsesses +1 more·Oct 22, 2025
Encoding in a high-dimensional Hilbert space improves noise resilience in quantum information processing. This approach, however, may result in cross-mode coupling and detection complexities, thereby reducing quantum cryptography performance. This fu...
Quantum walks as a tool to design robust quantum batteries: the role of topology and chirality
Simone Cavazzoni, Giovanni Ragazzi, Paolo Bordone +1 more·Oct 22, 2025
The maximum work that can be extracted from a quantum battery is bounded by the ergotropy of the system, which is determined by the spectral properties of the Hamiltonian. In this paper, we employ the formalism of quantum walks to investigate how the...

Quantum-information-inspired experiments in nuclear magnetic resonance spectroscopy may yield a pathway towards determining molecular structure and properties that are otherwise challenging to learn. We measure out-of-time-ordered correlators (OTOCs)...
Low overhead circuit cutting with operator backpropagation
Debarthi Pal, Ritajit Majumdar·Oct 22, 2025
Current quantum computers suffer from noise due to lack of error correction. Several techniques to mitigate the effect of noise have been studied, in particular to extract the expectation value of observables. One such technique, circuit cutting, par...
Absence of measurement- and unraveling-induced entanglement transitions in continuously monitored one-dimensional free fermions
Clemens Niederegger, Tatiana Vovk, Elias Starchl +1 more·Oct 22, 2025
Continuous monitoring of one-dimensional free fermionic systems can generate phenomena reminiscent of quantum criticality, such as logarithmic entanglement growth, algebraic correlations, and emergent conformal invariance, but in a nonequilibrium set...
