Remote sensing

A single photon has multiple bases (polarization, temporal, spatial, frequency) that can carry more information. The history of these photons is stored in these bases. By carefully processing the photons we can understand the environments these photons have been through. This is called quantum remote sensing.

QCI’s approach is unique (and patented) in its ability to perform single photon measurement in the LiDAR return signal such that the detection can be “tuned” to interrogate/measure at specific points (or volumes) in the environment. The precise ability to time gate the single photon signals as well as tune the detection in both frequency and phase space allows QCI’s system to leverage a quantum measurement to enhance the information gathered from a target that conventional LiDAR systems cannot achieve.


What it can do

We leverage quantum mechanical properties to perform remote sensing in novel ways.


The Quantum Photonic Vibrometer delivers unparalleled detection accuracy at the single photon level, outperforming traditional vibrometers. Line of sight is not needed, enabling detection around corners.


Our quantum-accelerated photon detection measurement means unmatched speed in data collection and processing.


Only quantum-aided remote sensing can achieve the granular observations needed to distinguish between the target object and its environment.

We introduce a novel upconversion imaging method that smoothly converts light from the near-infrared to the visible spectrum, boasting minimal loss and exceptional efficiency. By utilizing a spectrally separated 10 nanosecond pump within a nonlinear waveguide, we enhance the signal-to-noise ratio, making it easier to detect specific objects within a range of 1.5 meters with sub-centimeter precision. This outstanding noise reduction capability enables rapid LiDAR scanning in environments with high noise levels and limited photon availability, allowing us to swiftly capture 50 by 50 voxel images at an impressive rate of 10 frames per second.
