Quantum Photonics Transforms Holography

A brand-new quantum photonics technique has been created by researchers to produce three-dimensional images using lasers, much as in Star Trek and Star Wars. Their goal was to capture and reconstruct incredibly weak light beams of just a single photon of light.

This quantum photonics technology has the potential to transform 3D scene reconstruction and uncover a myriad of applications across varied sectors. Accurately recreating three-dimensional scenes has long been an aim in imaging. Applications ranging from driverless cars to augmented reality rely on improvements in this field.

The team’s quantum photonics technology has two key benefits over conventional holography techniques. Firstly, it exhibits amazing tolerance to mechanical instabilities such as vibrations during holographic recording. This novel technology enables researchers to capture holograms for longer durations, assuring higher precision than conventional holography, which requires limited exposure times due to susceptibility to vibrations. And secondly, our new technique can be employed to record holograms of self-luminous or remote objects.

It offers many opportunities, including the ability to characterize the spatial structure of single photon emission from quantum dots and single atoms and perform 3D imaging of far-off objects.

The team’s success was enabled by developments in quantum imaging and the availability of state-of-the-art commercial camera equipment. They resolved the required correlations for recording holograms using state-of-the-art cameras that offer exact timing and position stamps whenever they detect a single particle of light. This discovery illustrates the link between quantum science and technological progress.
