Noether Symmetries Generate Deterministic Energy-Harvesting Protocols
Ali Akil, M. Hamed Mohammady, Zihan Wang +1
We consider the general principles for when deterministic energy harvesting (DEH) is possible. DEH means absorbing energy from a fluctuating source without entropy being absorbed.…
Generalised Probabilistic Theories
Zujin Wen, Zihan Wang, Xiangjing Liu +1
We give an introduction to research associated with the generalised probabilistic theories framework, also known as the convex framework. States are real vectors representing lists…
Spatial Incompatibility Witnesses for Quantum Temporal Correlations
Xiangjing Liu, Harshit Verma, Yunlong Xiao +2
We introduce a witness-based framework for certifying quantum temporal correlations via the pseudo-density matrix (PDM) formalism, which is a spatiotemporal generalization of the d…
Non-unique decompositions of mixed states and deterministic energy transfers
Zihan Wang, Fei Meng, Oscar Dahlsten
We investigate the impact of non-unique decompositions of mixed states on energy transfer. Mixed states generally have non-unique decompositions into pure states in quantum theory…
Quantum harvester enables energy transfer without randomness transfer or dissipation
Fei Meng, Junhao Xu, Xiangjing Liu +1
We consider a foundational question in energy harvesting: given a partly random energy source, is it possible to extract the energy without also transferring randomness or acceptin…
Symmetry-guided gradient descent for quantum neural networks
Kaiming Bian, Shitao Zhang, Fei Meng +2
Many supervised learning tasks have intrinsic symmetries, such as translational and rotational symmetry in image classifications. These symmetries can be exploited to enhance perfo…
