Inferring the arrow of time in quantum spatiotemporal correlations
Xiangjing Liu, Qian Chen, Oscar Dahlsten
We consider how to tell the time-ordering associated with measurement data from quantum experiments at two times and any number of qubits. We define an arrow of time inference prob…
Information compression via hidden subgroup quantum autoencoders
Feiyang Liu, Kaiming Bian, Fei Meng +2
We design a quantum method for classical information compression that exploits the hidden subgroup quantum algorithm. We consider sequence data in a database with a priori unknown…
Unification of spatiotemporal quantum formalisms: mapping between process and pseudo-density matrices via multiple-time states
Xiangjing Liu, Zhian Jia, Yixian Qiu +2
We consider the relation between three different approaches to defining quantum states across several times and locations: the pseudo-density matrix (PDM), the process matrix, and…
Quantum walks as thermalizations, with application to fullerene graphs
Shyam Dhamapurkar, Oscar Dahlsten
We consider to what extent quantum walks can constitute models of thermalization, analogously to how classical random walks can be models for classical thermalization. In a quantum…
Quantum Causal Inference with Extremely Light Touch
Xiangjing Liu, Yixian Qiu, Oscar Dahlsten +1
We give a causal inference scheme using quantum observations alone for a case with both temporal and spatial correlations: a bipartite quantum system with measurements at two times…
