Lorentzian Spectral Geometry with Causal Sets

Yasaman K. Yazdi, Marco Letizia, Achim Kempf

We study discrete Lorentzian spectral geometry by investigating to what extent causal sets can be identified through a set of geometric invariants such as spectra. We build on prev…

Learning to Utilize Correlated Auxiliary Noise: A Possible Quantum Advantage

Aida Ahmadzadegan, Petar Simidzija, Ming Li +1

This paper has two messages. First, we demonstrate that neural networks that process noisy data can learn to exploit, when available, access to auxiliary noise that is correlated w…

Efficient method to create superoscillations with generic target behavior

Barbara Šoda, Achim Kempf

We introduce a new numerically stable method for constructing superoscillatory wave forms inan arbitrary number of dimensions. The method allows the construction of superoscillator…

The Dynamics of Entropies at the Onset of Interactions

Emily Kendall, Achim Kempf

At the onset of an interaction between two initially independent systems, each system tends to experience an increase in its n-Renyi entropies, such as its von Neumann entropy (n =…

Superadditivity of channel capacity through quantum fields

Koji Yamaguchi, Aida Ahmadzadegan, Petar Simidzija +2

Given that any communication is communication through quantum fields, we here study the scenario where a sender, Alice, causes information-carrying disturbances in a quantum field.…
