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