Quantum Circuit Fragments and Link Products in Continuous Variables

Amalina Lai, Graeme D. Berk, Minjeong Song +1

Quantum circuits are often drawn as complete processes, with fixed inputs and outputs. In many quantum-information tasks, however, the natural object is only a fragment of such a c…

Experimental Tabletop Petz recovery of a photonic qubit

Hui Li, Jinyan Chen, Yue Pan +4

The quantum information lost in open evolutions cannot be fully recovered, but partial recovery is possible. The Petz recovery map guarantees almost optimal recovery, notably if th…

No-go theorems on simulating uncertainty principle's signatures

Chung-Yun Hsieh, Minjeong Song, Shin-Liang Chen

Uncertainty principle, one of the most iconic features of quantum mechanics, was originally viewed as a fundamental limitation. Since the inception of quantum information science,…

Gaussian Atemporality: When Gaussian Quantum Correlations Imply Common Cause

Minjeong Song, Jayne Thompson, Matthew S. Winnel +4

Conventionally, covariances do not distinguish between spatial and temporal correlations. The same covariance matrix could equally describe temporal correlations between observatio…

Bipartite quantum states admitting a causal explanation

Minjeong Song, Arthur J. Parzygnat

The statistics of local measurements of joint quantum systems can sometimes be used to distinguish the spatiotemporal structure in which they were measured. We first prove that eve…

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…
