Monogamy of Gaussian quantum steering and entanglement in a hybrid qubit-cavity optomagnonic system with coherent feedback loop

Hamza Harraf, Mohamed Amazioug, Amjad Sohail +1 more·Oct 11, 2025

The monogamy of quantum correlations is a fundamental principle in quantum information processing, limiting how quantum correlations can be shared among multiple subsystems. Here we propose a theoretical scheme to investigate the monogamy of quantum ...

Fractional Aharonov-Bohm effect for retarded potentials

J. D. Franson·Oct 11, 2025

It has been suggested that the magnetic Aharonov-Bohm effect can be interpreted equally well as being due to a phase shift associated with an electron in an interferometer enclosing a magnetic flux, or as a phase shift associated with the electrons i...

On the validity of intermediate tracing in multiple quantum interactions

Reuven Ianconescu, Bin Zhang, Aharon Friedman +2 more·Oct 11, 2025

Interactions between many (initially separate) quantum systems raise the question on how to prepare and how to compute the measurable results of their interaction. When one prepares each system individually and let them interact, one has to tensor mu...

Defect-driven incoherent skin localization

Emmanouil T. Kokkinakis, Konstantinos G. Makris, Eleftherios N. Economou·Oct 11, 2025

The process of dephasing during wave evolution has traditionally been viewed as an obstacle to localization, leading to diffusion even in strongly disordered Hermitian lattices. In contrast, here we demonstrate how the interplay of dephasing with non...

Universal Manipulation of Quantum Synchronization in Spin Oscillator Networks

Shuo Dai, Zeqing Wang, Liang-Liang Wan +4 more·Oct 11, 2025

Quantum synchronization (QS) in open many-body systems offers a promising route for controlling collective quantum dynamics, yet existing manipulation schemes often rely on dissipation engineering, which distorts limit cycles, lacks scalability, and ...

Bounds on Eventually Universal Quantum Gate Sets

Chaitanya Karamchedu, Matthew Fox, Daniel Gottesman·Oct 11, 2025

Say a collection of $n$-qu$d$it gates $Γ$ is eventually universal if and only if there exists $N_0 \geq n$ such that for all $N \geq N_0$, one can approximate any $N$-qu$d$it unitary to arbitrary precision by a circuit over $Γ$. In this work, we impr...
