A new quantum technology developed by NIST combines photonic chips, atomic vapor cells, and specialized reflectors to create a highly sensitive radio frequency receiver. The device uses Rydberg atoms, which have unique quantum properties, to detect and measure radio frequency electric fields with unprecedented precision. The receiver consists of an integrated photonic chip that generates probe light, an atomic vapor cell containing the Rydberg atoms, and two opposing coupling light reflectors that guide and amplify the coupling laser light within the vapor cell. This innovative design allows the receiver to achieve extremely high sensitivity and low noise levels, making it suitable for various quantum sensing and communication applications. The technology has the potential to significantly advance quantum technologies by enabling more precise measurements and improved performance in quantum systems.
