Entanglement breaking in self-referential quantum feedback: a record bound and an exactly solvable loop
Eran Kopel
A feedback loop that returns a message into the process it describes defines a quantum channel on the message. We ask when such a loop preserves entanglement with a reference, that…
Regularization from Superpositions of Time Evolutions
Yakir Aharonov, Eliahu Cohen, Tomer Shushi
Short-time approximations and path integrals can be dominated by high-energy or large-field contributions, especially in the presence of singular interactions, motivating regulator…
Robust Control and Entanglement of Qudits in Neutral Atom Arrays
Amir Burshtein, Shachar Fraenkel, Moshe Goldstein +1
Quantum devices comprised of elementary components with more than two stable levels - so-called qudits - enrich the accessible Hilbert space, enabling applications ranging from fau…
Charge acceleration without radiation
Yakir Aharonov, Daniel Collins, Sandu Popescu
The existence of electromagnetic radiation - radio-waves, microwaves, light, x-rays and so on - is one of the most important physical phenomena, and our ability to manipulate them…
Quantum Key Distribution by Quantum Energy Teleportation
Shlomi Dolev, Kazuki Ikeda, Yaron Oz
Quantum energy teleportation (QET) is a process that leverages quantum entanglement and local operations to transfer energy between two spatially separated locations without physic…
Roadmap on Quantum Thermodynamics
Steve Campbell, Irene D'Amico, Mario A. Ciampini +66
The last two decades has seen quantum thermodynamics become a well established field of research in its own right. In that time, it has demonstrated a remarkably broad applicabilit…
