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…
Generalized Cross-Entropy Benchmarking for Random Circuits with Ergodicity
Bin Cheng, Fei Meng, Zhi-Jiong Zhang +1
Cross-entropy benchmarking is a central technique used to certify a quantum chip in recent experiments. To better understand its mathematical foundation and develop new benchmarkin…
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…
