Abstract
A device comprises a U-shaped cell configured to contain a quantum gas, a first waveguide coupled to an inlet of the U-shaped cell, and a second waveguide coupled to an outlet of the U-shaped cell. The device also comprises a multi-layer substrate including transmitter and receiver antennas that are aligned with the first and second waveguides, respectively, the substrate including a network of metal layers coupled to the transmitter and receiver antennas. The device also includes transmitter and receiver dies coupled to the transmitter and receiver antennas, respectively, by way of the network of metal layers, the substrate positioned between the U-shaped cell and the transmitter and receiver dies.
