Remote engineering of particle-like topologies to visualise entanglement dynamics
Fazilah Nothlawala, Bereneice Sephton, Pedro Ornelas +6 more·Mar 11, 2026
Skyrmions are a particle-like topology with a quantised skyrmion number, realised across condensed matter and photonic platforms alike. In quantum photonics, they constitute an emerging resource, promising robust quantum information encoding, so far ...
Practical Methods for Distance-Adaptive Continuous-Variable Quantum Key Distribution
Jonas Berl, Utku Akin, Erdem Eray Cil +2 more·Mar 11, 2026
Continuous-variable quantum key distribution (CV-QKD) is a promising quantum-safe alternative to classical asymmetric cryptography that enables two authenticated parties to establish a shared secret over a potentially eavesdropped quantum channel. A ...
Do single-shot projective readouts necessarily estimate the $T_1$ lifetime ?
Aparajita Modak, Sundeep Kapila, Bent Weber +3 more·Mar 11, 2026
When single-shot qubit readout protocols are adapted for multilevel systems, theoretical $T_1$ lifetime calculations often fall short of capturing the experimental lifetime trends. We identify extrinsic population dynamics as the fundamental origin o...
Coherence thermometry using multipartite quantum systems
Pranav Perumalsamy, Abhijit Mandal, Sovik Roy +1 more·Mar 11, 2026
We investigate, how finite temperature influences quantum coherence in multipartite open systems by analyzing a tripartite spin boson model subjected to non-Markovian dephasing. Two distinct environmental configurations are considered viz. independen...
Tight Quantum Speed Limit for Ergotropy Charging in the N-Qubit Dicke Battery
Anass Jad, Abderrahim El Allati·Mar 11, 2026
We derive and analytically prove a tight quantum speed limit (QSL) for ergotropy charging in the $N$-qubit Dicke quantum battery: the first-passage time to normalised ergotropy $ε$ satisfies $τ^{*}(ε) \geq \sqrt{Nε}/(2λ\sqrt{\bar{n}})$, where $λ$ is ...
Machine learning the arrow of time in solid-state spins
Xiang-Qian Meng, Zhide Lu, Ya-Nan Lu +9 more·Mar 11, 2026
Understanding the emergence of the thermodynamic arrow of time in microscopic systems is of fundamental importance, particularly given that unitary evolution preserves time-reversal symmetry. While projective measurements introduce temporal irreversi...
Geo-ADAPT-VQE: Quantum Information Metric-Aware Circuit Optimization for Quantum Chemistry
Mohammad Aamir Sohail, Toshiaki Koike-Akino·Mar 11, 2026
Adaptive ansatz construction has emerged as a powerful technique for reducing circuit depth and improving optimization efficiency in variational quantum eigensolvers. However, existing adaptive methods, including ADAPT-VQE, rely solely on first-order...
CHSH inequality always holds in bipartite qutrits with spin-1 observables
Hyunho Cha·Mar 11, 2026
We resolve a conjecture of Hanotel and Loubenets concerning CHSH inequality in bipartite qutrits. It states that nonseparable pure states of two qutrits do not violate the CHSH inequality when each party is restricted to spin-1 observables. We prove ...
Quantum entanglement provides a competitive advantage in adversarial games
Peiyong Wang, Kieran Hymas, James Quach·Mar 11, 2026
Whether uniquely quantum resources confer advantages in fully classical, competitive environments remains an open question. Competitive zero-sum reinforcement learning is particularly challenging, as success requires modelling dynamic interactions be...
Layered Performance Analysis of TLS 1.3 Handshakes: Classical, Hybrid, and Pure Post-Quantum Key Exchange
David G'omez-Cambronero, D. Munteanu, Ana Isabel Gonz'alez-Tablas·Mar 11, 2026
In this paper, we present a laboratory study focused on the impact of post-quantum cryptography (PQC) algorithms on multiple layers of stateful HTTP over TLS transactions: the TCP handshake, the intermediate TCP-TLS layer, the TLS handshake, the inte...
Light-Matter Interactions Beyond the Dipole Approximation in Extended Systems Without Multipole Expansion
Rishabh Dora, Roman Korol, Vishal Tiwari +2 more·Mar 10, 2026
We present a general theoretical framework to capture light-matter interactions beyond the electric-dipole approximation (EDA), applicable to extended nano- and microscale materials interacting with spatially structured electric fields without trunca...
Quantum batteries and time dilation
Esteban Martínez-Vargas·Mar 10, 2026
Is spacetime fundamental or can it be derived through quantum interactions? We propose here a way to describe time dilation solely from quantum mechanics. First we start by observing that any operational notion of time must imply some sort of regular...
Learning from Radio using Variational Quantum RF Sensing
Ivana Nikoloska·Mar 10, 2026
In modern wireless networks, radio channels serve a dual role. Whilst their primary function is to carry bits of information from a transmitter to a receiver, the intrinsic sensitivity of transmitted signals to the physical structure of the environme...
The Gamow Golden Rule of Multichannel Resonances
Rafael de la Madrid, Rodolfo Id Betan·Mar 10, 2026
We construct the Gamow Golden Rule of multichannel scattering, and use it to obtain the decay distributions, the partial decay constants, the partial decay widths, and the branching fractions of a resonance that has several decay modes. We exemplify ...
Reducing Quantum Error Mitigation Bias Using Verifiable Benchmark Circuits
Joseph Harris, Kevin Lively, Peter Schuhmacher·Mar 10, 2026
We present a simple, malleable and low-overhead approach for improving generic biased quantum error mitigation (QEM) methods, achieving up to 15% fidelity improvements over standard QEM on 100-qubit circuits with up to 2000 entangling gates. We do so...
Are quantum trajectories suitable for semiclassical approximations?
Alfredo M. Ozorio de Almeida·Mar 10, 2026
The quantum trajectories in the de Broglie-Bohm formulation of quantum mechanics depend on an additional quantum potential derived from the full wave solution of Schrödinger's equation. The task of supplying collectively all the correct quantum resul...

Zichang He, Anuj Apte, Brandon Augustino +4 more·Mar 10, 2026
Demonstrating quantum heuristics that outperform strong classical solvers on large-scale optimization remains an open challenge. Here we introduce Regularized Warm-Started QAOA (RWS-QAOA), which initializes qubits by minimizing expected energy with a...
Digital dissipative state preparation for frustration-free gapless quantum systems
Johannes Feldmeier, Yu-Jie Liu, Mikhail D. Lukin +1 more·Mar 10, 2026
Preparing algebraically correlated ground states of quantum many-body systems is an important, yet challenging task for quantum simulation. We introduce a protocol that employs local projective measurements and unitary feedback for frustration-free g...
Localized intrinsic bond orbitals decode correlated charge migration dynamics
Imam S. Wahyutama, Madhumita Rano, Henrik R. Larsson·Mar 10, 2026
For decades, scientists have studied the intricate charge migration dynamics, where after ionization a localized charge distribution ("hole") migrates across the molecule on a femtosecond timescale. This has the potential for controlling electrons in...
A complete classification of 2d symmetry protected states with symmetric entanglers
Alex Bols, Wojciech De Roeck, Michiel De Wilde +1 more·Mar 10, 2026
We consider symmetry protected topological states of 2d quantum spin systems, with a finite symmetry group $G$. It has been conjectured that such states are classified by the cohomology group $H^3(G,U(1))$, but the completeness of this classfication ...
