In this project we develop a novel infrared camera with low noise and high detection efficiency for biomedical applications of optical coherence tomography (OCT) using quantum materials. OCT is a technique used to image the back of the eye and allow for the diagnosis of detrimental eye conditions, for e.g., macular degeneration, diabetic retinopathy and glaucoma. It can also be used for early detection of Alzheimer’s disease. However, current OCT systems are limited by their low sensitivity and spatial resolution. To provide more precise early diagnosis of potentially blinding ocular diseases, we utilize the unique expertise of a collaborative team of researchers to develop an infrared camera with sub-micron resolution and single-photon sensitivity: design and nano fabrication of quantum sensors (Reimer), design and fabrication of CMOS electrical read-out circuits to make the camera (Karim and Levine), and extensive knowledge and research expertise in the area of OCT (Bizheva). At the heart of the infrared camera is a single photon detector recently developed through another TQT-supported project, Next Generation Quantum Sensors. This sensor is based on nanostructured arrays of tapered semiconductor nanowires and is capable to detect light with high efficiency, speed, and timing resolution over an unprecedented wavelength range from the UV to infrared, all while operating at room temperature. This sensor will be integrated into a prototype camera and into existing OCT systems to realize enhanced OCT images of the human retina and cornea in-vivo.

Entangled States of Beams and their Applications
Summary With David Cory and collaborators at the National Institute of Standards and Technology (NIST) we explore how to engineer beams of neutron or photons that carry entanglement. The degrees of freedom that can be entangled include spin (polarization), momentum, displacement, and angular momentum. These have potential applications ranging from studies of helical internal magnetic fields […]

Quantum Sensing Applications using Quantum Communication Technology
Summary The Quantum Encryption and Science Satellite provides a platform to develop and deploy quantum sensing and metrology via photonic channels. This project will build upon ‘free-space’ quantum communication technology and explore new approaches and methods to advance two primary applications: quantum-enhanced telescopes, and spectroscopic sensing for methane detection in the atmosphere. For the […]

Applications of Neutron Interferometry and Structured Neutron Beams
Summary Neutrons are a powerful probe of matter and physics due to their Angstrom size wavelengths, electric neutrality and relatively large mass. In this project, we develop quantum sensors that exploit these attributes to increases the precision of measurements of fundamental forces and materials structure. With David Cory, Alexander Cronin of the University of Arizona, […]
