Article Synopsis
- This study introduces boson sampling using interacting atoms from the noncondensed fraction of a Bose-Einstein condensate (BEC) gas as a method to explore complex computational problems and quantum supremacy in many-body systems.
- By applying the Hafnian master theorem, the researchers derive calculations related to atom numbers and their statistics, highlighting the significance of interatomic interactions in the system.
- The findings suggest that essential components for ♯P-hardness, such as squeezing and interference, arise naturally in the gas system without needing external squeezed boson sources.
When ground-state atoms are accelerated through a high Q microwave cavity, radiation is produced with an intensity which can exceed the intensity of Unruh acceleration radiation in free space by many orders of magnitude. The reason is a strong nonadiabatic effect at cavity boundaries and its interplay with the standard Unruh effect. The cavity field at steady state is still described by a thermal density matrix under most conditions.
