Project Overview

Quantum Ghost Imaging

In this project we study images that are carried by entangled photons. Ghost imaging is the situation where one photon goes through an object and the entangled partner displays the image of the object in a separate camera. This is done with a quantum source of light that produces entangled photons. In the experiment we send one stream of photons toward a transmissive object and then to a detector, and at the same time we send the entangled partners, going in separate directions to a camera. The first photons trigger the camera shutter, and the acquired image is of the transmissive object in the path of the photon that is not detected by the camera. This situation has a lot of potential applications, such as in biomedical imaging, in addition to fundamental interest for investigating quantum phenomena. An intriguing aspect of quantum entanglement is that we can create a situation where two entangled photons carry a common image that is distinct to the image that each individual photon carries.

In this project the student will be working in the lab creating entangled-photon situations and incorporating the use of a new single photon camera that we have purchased.
