What will the Internet be like in the future? Let’s explore the most remarkable technologies that could soon come into our lives.

Quantum Teleportation Opens the Way for Quantum Internet!

For the first time, an international team of physicists succeeded to teleport information into a solid-state quantum memory, which is a prerequisite for a future quantum Internet.

In quantum teleportation, no mass is transferred but only the information that describes the state of the quantum system that transmits the signal. The other quantum system receives all the properties of the transmitted quantum state and creates an exact copy.

This kind of technology is behind a new generation of computer systems, including quantum Internet, which among other things promises to exchange information between computers in a completely secure way.

The new research developments took place at the University of Geneva where an international scientific team led by Felix Bussières used a crystal doped with rare-earth ions as quantum memory and teleported information to it via a conventional means such as optical fiber.

One of the basic requirements for the teleportation of information is creating an entangled photon with a wavelength comparable to the diameter of the optical fiber. In quantum physics, the entangled particles are the pairs of particles whose quantum properties are interacting (and can be described by a common function), even when they are far apart.

Creating entangled photons with such strict requirements for wavelength was difficult enough for researchers, who nevertheless managed to produce such pairs, even in two different infrared frequencies.

The information that was finally teleported was the polarization of a photon with a wavelength of 1338nm.

The signal traveled through an optical fiber 12 km long and was successfully transmitted by one quantum memory to another, and the subsequent measurements of the polarization of the photon-receiver were in exact accordance with those provided by the quantum theory.

This is another important step in quantum computing, which has begun to attract ever-growing research interest.

LiFi Technology: Use Your Light Bulb to Access the Internet!

LiFi (visible light communication) is the transformation of the light bulb into a wireless communication route that may replace Wi-Fi in the future.

Li-Fi inventor, the German physicist Harald Haas, believes that the visible light spectrum can be used to transmit data, as its spectral width is much larger than that of the conventional radio frequencies, and it, therefore, has the potential to transmit higher bandwidths.

Wi-Fi technology has become very popular, but there are complaints that the wireless signal is unstable, access is slow, and Wi-Fi hotspots are too few while users are ever-increasing. Now, there is a new technology that can address these issues.

The light bulb has long been regarded as a coveted symbol of inspiration for inventors. However, for Herald Haas, the light bulb itself brought him inspiration.

Together with his team at the University of Edinburgh, Haas invented a patented technology, using a flashlight for wireless transmission of digital information, a technique commonly referred to as visible light communication (VLC).

Haas said: “My greatest vision is that light bulbs will become broadband communications equipment so that the light bulb is not only able to provide lighting and will also become a necessary tool.”

Haas claims that by providing ordinary LED bulbs with an installed microchip, they will be able to flicker at a frequency of millions of times per second, allowing their use to send data.

In this way, LED bulbs can rapidly transfer binary-coded information. However, to the naked eye, the flickering is not visible and can only be detected by the light-sensitive receiver.

Haas said: “This is similar to sending Morse code through a torch, but faster, and uses an alphabet that can be understood by a computer.”

Thus, this technology can provide you with a wireless Internet connection, as long as you have a light bulb. The number of the world’s light bulbs is estimated at about 14 billion. In fact, this means that every street can become an Internet access point.

Yet, the nicknamed “Li-Fi” technology not only can enhance the coverage of the Internet. The main wireless data transmission technology, Wi-Fi relies on radio frequencies, which only make up a small part of the entire electromagnetic spectrum.

With increasing user demand for wireless internet, the available radio spectrum is less and less.

Satellite Wi-Fi That Could Give Free Access to the Global Network

A team of IT specialists from the Media Development Investment Fund developed a project for new network access to the Internet, which will be completely free of charge and will cover the entire planet.

The product called Outernet provides placing miniature devices CubeSats on the orbit of the Earth, which will be capable of receiving data from ground stations and transferring them to the users. Outernet is something like a huge Wi-Fi-router, covering all continents.

Thus, the next step in the evolution of information technology will be made. Outernet will offer unprecedented convenience in use, which will guarantee the comfort of users, optimize the query execution time, and provide high speed and quality of data processing.

The launch of hundreds of small satellites CubeSats is scheduled for the next year. Information transfer will be done through the “datacasting” technology, which involves the use of “wide” radio waves.

According to the developers of the product, in this way, Outernet will transmit Internet data to any Wi-Fi compatible device at any point on the globe.

The Head of Innovation at MDIF Syed Karim stressed that Outernet will be unattainable for censorship and able to provide complete privacy of user information.

If the company plans are implemented, even those users who are today outside the reach of the Internet or cannot afford it for financial reasons will have the opportunity to have Internet access.

Quantum Internet, Wi-Fi access from a lightbulb, and a global network provided by a satellite router… All this sounds like science-fiction, and yet, all these technologies can soon be implemented! Can’t wait to see when it happens!
