Quantum Key Distribution with Imperfections: Recent Advances in Security Proofs
Patrick Andriolo, Esteban Vasquez, Elizabeth Agudelo +3
In contrast to classical public-key cryptosystems, where the security of encoded messages relies on on computational assumptions, Quantum Key Distribution (QKD) enables two distant…

Soft gravitons in three dimensions
Jordan Cotler, Kristan Jensen, Stefan Prohazka +2
We consider quantum gravity with zero cosmological constant in three dimensions. First, we show that pure quantum gravity can be written as a magnetic Carrollian theory living on n…

Quantizing Carrollian field theories
Jordan Cotler, Kristan Jensen, Stefan Prohazka +3
Carrollian field theories have recently emerged as a candidate dual to flat space quantum gravity. We carefully quantize simple two-derivative Carrollian theories, revealing a stro…
