One beam is sent towards the object you\u2019re recreating and is reflected onto a special camera. The second beam is sent directly onto the camera. By measuring the differences in light, its phase, you can reconstruct a 3D image. A key property in this is the wave\u2019s coherence.<\/p>\n<p>The quantum hologram shares some of these principles but its execution is very different. It starts by splitting a laser beam in two, but these two beams will not be reunited. The key is in the splitting. As you can see in the image below, the blue laser hits a nonlinear crystal, which creates two beams made of pairs of entangled photons.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers have used a quantum mechanical property to overcome some of the limitations of conventional holograms.
