Our research is on the leading edge of quantum and optical phenomena and information science.
Raytheon BBN’s Quantum Information Processing (QuIP) group is an interdisciplinary team of physicists, mathematicians, information theorists, and systems engineers with expertise in superconducting quantum circuits, quantum memory physics, quantum and classical information theory, and classical optical networking.
The QuIP group’s research is enabling vertically integrated, next generation quantum enhanced sensing, scalable quantum communications, and quantum computing technology and systems, from the physical layer, to component level, to applications. Our projects are committed to the goal of engineered systems which harness novel quantum phenomena for massive improvements in performance or fundamentally new capabilities.
QuIP Laboratory for Bits and Waves
The Laboratory for Bits and Waves exploits quantum, optical and superconducting phenomena for achieving revolutionary breakthroughs in computation and communication systems. With over 1100 square feet, the Lab is comprised of a cryogenic lab, conducting state of the art research superconducting technologies and contains two 10 mK dilution refrigerators; and an optical lab conducting research on classical and quantum communications, and including a high quality entanglement source.
The QuIP group is exploring concepts for using quantum states in remote sensing applications. Our goal is to design and build systems which use quantum devices and information theory to surpass the limits of sensitivity of current devices. Successful development of such concepts would allow Radar, Laser Radar (LADAR), and other remote sensing systems to exceed the performance limits of today’s technology, which use only classical (non-quantum) states.
In the DARPA Quantum Sensors Program we were part of a team that proposed and demonstrated a concept for improving LADAR sensors, which can interrogate targets at a distance of 10 km using infrared light at wavelengths around 1.0 micron. Similarly, we led a modeling effort that showed that these concepts could improve the resolution of a LADAR system by approximately 10 times (three times in each transverse dimension). Successful transition of this technology to military LADAR systems would improve the ability to clearly distinguish two or more closely spaced objects or resolve high frequency features in remote imaging.
- Phase sensitive amplification for LADAR
- Entangled, assisted imaging (quantum illumination)
- Photon efficient imaging
- JPAs, microwave photon memories
- Novel compressed sensing and sub-SQL estimation algorithms and protocols
- Optical frequency entanglement source
Our team is also focusing its efforts on designing and deploying scalable quantum networks. Long distance (continental scale) quantum networks would enable quantum key distribution and direct secure communications at distances impossible with today’s technology (which are limited to ~100 km). The same technology would also enable distributed quantum computation among physically distant processors, greatly increasing the achievable scale of quantum algorithms and furthermore. In addition to quantum communications, we are developing methods to approach the ultimate physical capacity limits of classical optical communications.

The QuIP group has been developing and demonstrating superconducting qubits with a systems perspective. We are interested in all aspects of quantum computing systems which include systems control as well as coupled qubit design and measurement. We are advancing the state-of-the-art in room temperature control electronics with high-precision, low-noise, and scalable control systems and experimenting with various qubit types with a focus on understanding the characteristics of each design approach and their respective advantages towards quantum computing. We are building a complete platform for designing, controlling, and measuring an 8-16 Qubit processor and developing additional quantum optics related applications. We are leaders in providing the best service for RT control/readout hardware, software (optimizers and domain specific languages) and peripheral microwave components (filters, amps).
