This technology is a method of controlling the coupling and polarity of microwave fields for quantum applications.

Unmet Need: Precise control of the polarization of microwave fields

The use of microwave fields is increasingly prevalent in modern day technology, from cooking to wireless communication. Precise, fine-tuned control of the wavelength, power, and polarization of microwaves is particularly critical for practical quantum applications, such as simulation and computing. However, current methods of controlling microwave fields are limited by their precision and long coherence times.

The Technology: Circularly polarized microwave fields for quantum state control

This technology is a method of precisely controlling the polarization of microwave fields. This technology is a planar cloverleaf-shaped device with four loop antennas precisely phases microwaves to modulate molecular rotational states and thus control quantum states. As such, this technology may enable applications that require increased atomic state control, including atomic and quantum technologies.

Applications:
