Quantum Teleportation Between Atomic Systems Over Long Distances
Researchers have been able to teleport information from light to light at a quantum level for several years. In 2006, researchers at the Niels Bohr Institute succeeded in teleporting between light and gas atoms. Now the research group has succeeded in teleporting information between two clouds of gas atoms and to carry out the teleportation -- not just one or a few times, but successfully every single time.
The results are published in the scientific journal, Nature Physics.
"It is a very important step for quantum information research to have achieved such stable results that every attempt will succeed," says Eugene Polzik, professor and head of the research center Quantop at the Niels Bohr Institute at the University of Copenhagen.
The experiments are conducted in the laboratories of the research group in the basement under the Niels Bohr Institute. There are two glass containers, each containing a cloud of billions of caesium gas atoms.
The two glass containers are not connected to each other, but information is teleported from the one glass cloud to the other by means of laser light. The light is sent into the first glass container and then that strange quantum phenomenon takes place, the light and gas become entangled. The fact that they are entangled means that they have established a quantum link -- they are synchronised.
Both glass containers are enclosed in a chamber with a magnetic field and when the laser light (with a specific wavelength) hits the gas atoms, the outermost electrons in the atoms react -like magnetic needles -- by pointing in the same direction. The direction can be up or down, and it is this direction that makes up quantum information, in the same way that regular computer information is made up of the numbers 0 and 1.
The gas now emits photons (light particles) containing quantum information. The light is sent on to the other gas container and the quantum information is now read from the light and registered by a detector. The signal from the detector is sent back to the first container and the direction of the atoms' electrons are adjusted in relation to the signal. This completes the teleportation from the second to the first container.
New method
The experiments are carried out at room temperature and the gas atoms therefore move at a speed of 200 meters per second in the glass container, so they are constantly bumping into the glass wall and thus lose the information they have just been encoded with. But the research group has developed a solution for this.
"We use a coating of a kind of paraffin on the interior of the glass contains and it causes the gas atoms to not lose their coding, even if they bump into the glass wall," explains Professor Eugene Polzik. It sounds like an easy solution, but in reality it was complicated to develop the method. Another element of the experiment was to develop the detector that registers the photons. Here the researchers developed a particularly sensitive detector that is very effective at detecting the photons. The experiments therefore works every single time.
But it is one thing to perform tests in a laboratory and quite another to apply it in wider society! In the experiment, the teleportation's range is ½ meter -- hardly impressive in a world where information must be transported around the world in no time.
"The range of ½ meter is entirely due to the size of the laboratory," explains Eugene Polzik with a big smile and continues -- "we could increase the range if we had the space and, in principle, we could teleport information, for example, to a satellite." The stable results are an important step towards the quantum communication network of the future.

/ About us
Founded by Russian entrepreneur Dmitry Itskov in February 2011 with the participation of leading Russian specialists in the field of neural interfaces, robotics, artificial organs and systems.
The main goals of the 2045 Initiative: the creation and realization of a new strategy for the development of humanity which meets global civilization challenges; the creation of optimale conditions promoting the spiritual enlightenment of humanity; and the realization of a new futuristic reality based on 5 principles: high spirituality, high culture, high ethics, high science and high technologies.
The main science mega-project of the 2045 Initiative aims to create technologies enabling the transfer of a individual’s personality to a more advanced non-biological carrier, and extending life, including to the point of immortality. We devote particular attention to enabling the fullest possible dialogue between the world’s major spiritual traditions, science and society.
A large-scale transformation of humanity, comparable to some of the major spiritual and sci-tech revolutions in history, will require a new strategy. We believe this to be necessary to overcome existing crises, which threaten our planetary habitat and the continued existence of humanity as a species. With the 2045 Initiative, we hope to realize a new strategy for humanity's development, and in so doing, create a more productive, fulfilling, and satisfying future.
The "2045" team is working towards creating an international research center where leading scientists will be engaged in research and development in the fields of anthropomorphic robotics, living systems modeling and brain and consciousness modeling with the goal of transferring one’s individual consciousness to an artificial carrier and achieving cybernetic immortality.
An annual congress "The Global Future 2045" is organized by the Initiative to give platform for discussing mankind's evolutionary strategy based on technologies of cybernetic immortality as well as the possible impact of such technologies on global society, politics and economies of the future.
Future prospects of "2045" Initiative for society
2015-2020
The emergence and widespread use of affordable android "avatars" controlled by a "brain-computer" interface. Coupled with related technologies “avatars’ will give people a number of new features: ability to work in dangerous environments, perform rescue operations, travel in extreme situations etc.
Avatar components will be used in medicine for the rehabilitation of fully or partially disabled patients giving them prosthetic limbs or recover lost senses.
2020-2025
Creation of an autonomous life-support system for the human brain linked to a robot, ‘avatar’, will save people whose body is completely worn out or irreversibly damaged. Any patient with an intact brain will be able to return to a fully functioning bodily life. Such technologies will greatly enlarge the possibility of hybrid bio-electronic devices, thus creating a new IT revolution and will make all kinds of superimpositions of electronic and biological systems possible.
2030-2035
Creation of a computer model of the brain and human consciousness with the subsequent development of means to transfer individual consciousness onto an artificial carrier. This development will profoundly change the world, it will not only give everyone the possibility of cybernetic immortality but will also create a friendly artificial intelligence, expand human capabilities and provide opportunities for ordinary people to restore or modify their own brain multiple times. The final result at this stage can be a real revolution in the understanding of human nature that will completely change the human and technical prospects for humanity.
2045
This is the time when substance-independent minds will receive new bodies with capacities far exceeding those of ordinary humans. A new era for humanity will arrive! Changes will occur in all spheres of human activity – energy generation, transportation, politics, medicine, psychology, sciences, and so on.
Today it is hard to imagine a future when bodies consisting of nanorobots will become affordable and capable of taking any form. It is also hard to imagine body holograms featuring controlled matter. One thing is clear however: humanity, for the first time in its history, will make a fully managed evolutionary transition and eventually become a new species. Moreover, prerequisites for a large-scale expansion into outer space will be created as well.
