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…

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.…

Transmission of quantum information through quantum fields

Petar Simidzija, Aida Ahmadzadegan, Achim Kempf +1

We investigate the quantum channel consisting of two localized quantum systems that communicate through a scalar quantum field. We choose a scalar field rather than a tensor or vec…

Probing geometric information using the Unruh effect in the vacuum

Aida Ahmadzadegan, Fatemeh Lalegani, Achim Kempf +1

We present a new method by which, in principle, it is possible to "see in absolute darkness," i.e., without exchanging any real quanta through quantum fields. This is possible beca…

Quantum Shockwave Communication

Aida Ahmadzadegan, Eduardo Martin-Martinez, Achim Kempf

We present a scheme to produce shockwaves in quantum fields by means of pretimed emitters. We find that by suitably pre-entangeling the emitters, the shockwave's energy density can…
