Researchers from Wits University and Universitat Autònoma de Barcelona show how controlling the structure of photons in space and time enables tailored quantum states for next-generation communication, sensing and imaging.

Photons themselves have no time. This means that. Theoretically, it is possible to save information in photons. And that information remains as long as the photons. Information can be saved. Bending a photon into curves. This thing makes photon a good information transporter, if those curves remain in their form. This technology is under research. Photonics allows us to circumnavigate the theory of relativity. The idea is that two photons are in a superposition and quantum entanglement. 

Then those photons can transmit information virtually faster than light. Theoretically, it is possible to create a quantum entanglement. There, the receiving side moves precisely in the same moment as the transmitting particle. The idea is that the quantum entanglement would be like a stick. 

In the case that we could create a stick. That is 4,5 light-years long, we could transmit information between Earth and Alpha Centauri faster than radio waves. This means that when the astronaut pushes that stick in Alpha Centauri. The receiver sees that stick’s movement. The stick acts like an ultra-long gramophone stylus. But information travels as a wave between superpositioned and entangled particles. 

But sometimes quantum entanglement seems to break the speed of light. The thing that causes. This phenomenon is that the speed of light is a cosmic constant that depends on the medium through which light travels. The speed of light is slower in a medium than in a vacuum. This means the speed of light is slower in water than in air. The thing that slows or limits the speed of light. This is the scattering effect. 

We can think that. If. There is a vacuum tunnel in the air. Light travels faster. In that vacuum tunnel than outside it. The reason why quantum entanglement seems to break the laws of physics is simple. Information travels in the quantum tunnel. That turns the scattering effect weaker. Maybe someday we can transport information through space and time by using superpositioned photons. The idea is that. Another photon will be put into the higher energy level. By trapping it. In the chamber. That transmits energy into it. And this slows time in that photon. This photon will transmit information to another photon. That energy level is lower. Otherwise. If we want. To transmit information. 

The photon itself has no time. But it’s possible. That. Time moves more slowly in a photon. Whose energy level is higher than that of another photon. The system that transports the information from the future could be the ball. There is a quantum-sized black hole. The black hole itself or the photon. That which is positioned around the black hole transmits information to another photon. That is at a lower energy level. The idea is that. Time dilation in a part of this system. That is, the higher energy level. Makes time travel slower in that part. Then quantum entanglement transmits information to the past. 

We must not transmit information from a photon itself. We can transmit information from the field that surrounds a photon. So. If reseachers want to transmit information from the future, they must create quantum entanglement through time. They must keep the object. That transmits information. On a higher energy level. Than the energy level. It is in the receiving particle. That is one thing that could be possible in the future. The ability to transport information from the future to the past is one of the most fascinating things that we can imagine.
