Dimension Reduction for Quantum Adaptive Agents
Rishi Sundar, Thomas J. Elliott
Adaptive agents realise complex reactive behaviours by using a memory of past input stimuli and output actions to guide structured future responses. Quantum adaptive agents can ope…
Efficient optimisation of multi-parameter quantum control protocols for strongly-coupled systems
Sion Meredith, Oliver Dudgeon, Wojciech Bukalski +4
Achieving high-fidelity control in the presence of strong non-Markovian noise is critical for the optimization of emergent solid-state quantum devices. We present a highly efficien…
Variational Quantum Dimension Reduction for Recurrent Quantum Models
Chufan Lyu, Ximing Wang, Mile Gu +2
Recurrent quantum models (RQMs) realize sequential quantum processes through repeated application of a unitary operation on a memory system coupled with a series of output register…
Energetic advantages for quantum agents in online execution of complex strategies
Jayne Thompson, Paul M. Riechers, Andrew J. P. Garner +2
Agents often execute complex strategies -- adapting their response to each input stimulus depending on past observations and actions. Here, we derive the minimal energetic cost for…
Causal classification of spatiotemporal quantum correlations
Minjeong Song, Varun Narasimhachar, Bartosz Regula +2
From correlations in measurement outcomes alone, can two otherwise isolated parties establish whether such correlations are atemporal? That is, can they rule out that they have bee…
Dimension reduction in quantum sampling of stochastic processes
Chengran Yang, Marta Florido-Llin`as, Mile Gu +1
Quantum technologies offer a promising route to the efficient sampling and analysis of stochastic processes, with potential applications across the sciences. Such quantum advantage…
