Is it possible to send a message, without sending anything?

We contact each other via the particles. Calls and messages are riding on the waves of light, websites and photos are uploaded on the electrons. All communications are inherently physical. Information is recorded and transmitted real objects, even if we can’t see them. Physics is also connected to the world, when you communicate with him. They send flashes of light in the direction of the particles or atoms and waiting for the light to come back. Light interacts with particles of matter, and changing the behaviour of the light it sheds light (pardon the pun) on the properties of particles — even though these interactions often change and particles. The process of this communication is called a dimension.

Even particles connected with other particles. The strength of the electromagnetic force between two electrons is transmitted by the particles of matter and quarks, which are crammed inside the protons as they exchange gluons. Physics essentially deals with the reactions.

Information is always via the interaction between the particles or with itself. We consist of particles which contact each other, and we learn about their environment by interacting with it. The better we understand this interaction, the better we understand the world and themselves.

Physicists already know that the interaction is local. As urban policy, the effect of particles is limited to their immediate surroundings. However, interaction is very difficult to describe. Physicists have to treat the particles with respect and add complex terms to their lonely existence in order to simulate interaction with other particles. The resulting equations cannot be solved. Therefore, physicists have only to estimate a single particle. Still, the measurement of the interactions of atomic and subatomic particles to create the most precise area of physics.

Quantum mechanics is a complete theory of particles, describing their measurement and interaction. Over the past few decades, as computers began to explore the quanta of this theory has grown to incorporate information well. The implications of quantum mechanics for measurements and interactions between particles are extremely strange. Its implications for information even more strange.

One of the strangest consequences denies the material basis of communication and common sense. Some physicists believe we may be able to communicate without passing particles. In 2013 physicist-enthusiast Hatim Salih even wrote the Protocol, along with professionals in which information is obtained from the location in which the particle never traveled. Information can be ethereal. Communication, it turns out, can be not so physical.

Last April in the Proceedings of the National Academy there was a short article on the subject of the Protocol Salih. Most of the authors were members of the University of science and technology of China in its branches in Shanghai and Hefei. The last author was Jiang-Wei pan, an outstanding physicist who has developed a constellation of communication satellites using quantum mechanics. Recently, he used his network for the transmission of entangled particles over a distance of 1200 kilometers.

Pan and his colleagues give approximately the month. But the document, which they published in April, in collaboration of Yuan Cao and Yu-Huay Lee, was exceptional. They described an experiment which sent a black and white image of the Chinese host, not passing any particle.

Extraordinary claims require extraordinary evidence — even if they doubt the person, the approval of which was taken as a basis for the work of a group of scientists, Leo Weidman. Weidman and others have tried to interpret these results in ten years. We may understand quantum theory.

Physicists struggling to decipher what quantum mechanics says about reality and the material world. But this theory only begins to speak. Physicists are now questioning the uncertainty that follows from quantum theory, because even a very weak measurement reveal information that was once considered secret. At stake are the concepts of measurement and interactions as well as fundamentals of future information technologies.
