Collective Enhancement of Nuclear Excitation for a Nuclear Quantum Battery
Pravin Kumar Dahal, Kieran Hymas, Jack Muir +1
Current implementations of quantum batteries are constrained by limited energy density and short retention times associated with the electronic or molecular excitations. Here we pr…
Locally Passive, Globally Charged Quantum Batteries: Coherence-Controlled Work and the Robustness of the Stored Charge
Asad Ali, Saif Al-kuwari, James Q. Quach
A solvable charger--battery model is introduced in which quantum coherence controls both where a quantum battery's charge is stored and how robustly it survives noise. Charging con…
Fine-Tuning Large Language Models for Quantum Reasoning
Katherine Ip, Casey R. Myers, Udaya Parampalli +2
Large language models (LLMs) exhibit abilities beyond natural language modelling and text generation. Recent advances in their reasoning capabilities have spurred interest in apply…
Counterdiabatic Raman Atom Optics for Compact High-Sensitivity Gravimetry
Asad Ali, Hamid Arian Zad, Saif Al-Kuwari +6
Large-momentum-transfer (LMT) atom interferometry provides a route toward enhanced inertial sensitivity in compact quantum sensors, but its scalability is limited by the accumulati…
Quantum entanglement provides a competitive advantage in adversarial games
Peiyong Wang, Kieran Hymas, James Quach
Whether uniquely quantum resources confer advantages in fully classical, competitive environments remains an open question. Competitive zero-sum reinforcement learning is particula…
Towards Real-time Control of a CartPole System on a Quantum Computer
Nguyen Truong Thu Ngo, Väinö Mehtola, Jérome Lenssen +4
The application of quantum reinforcement learning (QRL) to real-time control systems faces significant challenges regarding hardware latency, noise susceptibility, and learning con…
