What can unitary sequences tell us about multi-time physics?
1 1
Gregory A. L. White, Felix A. Pollock, Lloyd C. L. Hollenberg, Charles D. Hill, and Kavan Modi, Quantum 9, 1695 (2025). Multi-time quantum processes are endowed with the same richness as multipartite states, including temporal entanglement and exotic causal structures. However, experimentally...

Mark Zhandry, Quantum 9, 1696 (2025). We show how to construct pseudorandom permutations (PRPs) that remain secure even if the adversary can query the permutation, both in the forward and reverse directions, on a quantum superpo…

Controlling measurement-induced phase transitions with tunable detector coupling
1 1
Ritu Nehra, Alessandro Romito, and Dganit Meidan, Quantum 9, 1697 (2025). We study the evolution of a quantum many-body system driven by two competing measurements, which induces a topological entanglement transition between two distinct area law phases. We employ…

Approximate inverse measurement channel for shallow shadows
1 1
Riccardo Cioli, Elisa Ercolessi, Matteo Ippoliti, Xhek Turkeshi, and Lorenzo Piroli, Quantum 9, 1698 (2025). Classical shadows are a versatile tool to probe many-body quantum systems, consisting of a combination of randomised measurements and classical post-processing computations. In a recently in…
