Technical Abstract (Limit 2000 characters, approximately 200 words)

Physical Sciences Inc. (PSI) and the University of Illinois Urbana-Champaign (UIUC) will develop integrated optical frequency shifters to enable Quantum-memory Wavelength-Division Multiplexing (QWDM). Our approach will enable the connection of multiple quantum memory registers across a free-space or fiber optical channel, increasing the bandwidth of near-term quantum networks by 10–100x. As most optical quantum memories operate at a single wavelength we cannot readily apply wavelength-division multiplexing (WDM) techniques to increase the bandwidth of a quantum link. To overcome this challenge, we utilize high-efficiency frequency shifters at the transmitter to shift each quantum register within a memory unit onto a separate wavelength channel that we can combine using standard WDM techniques. After transmitting the multiplexed signal over a free-space or fiber link, a complimentary device at the receiver will de-multiplex the photons and a second set of frequency shifters will shift the wavelengths back to original native frequency of the quantum memory’s register. These devices will pave the way for the creation of a highly scalable quantum networks using QWDM.

Potential NASA Applications (Limit 1500 characters, approximately 150 words)

The development of quantum communications and networks are a key technology to enable secure communication, sensor arrays, and quantum computer networks. Our proposed technology will enable wavelength-division multiplexing techniques to greatly increase the bandwidth of NASA’s free-space or fiber quantum links, such as those interfacing quantum memories as well as heterogeneous single- and entangled-photon sources.

Potential Non-NASA Applications (Limit 1500 characters, approximately 150 words)

Future quantum networks will require quantum memories (QM) that are linked by photons transmitted over physical channels. As most QMs utilize a fixed optical frequency, QWDM are a general-purpose component to scale bandwidth without introducing additional physical channels. Such frequency conversion methods are applicable to photons from QMs, as well as the sources of the photons themselves.
