Scientists Set New 'Quantum Teleportation' Record
An international team of physicists has broken the distance record for "quantum teleportation" with the instantaneous transmission of quantum states encoded in photons over the 143 kilometers (89 miles) separating facilities on the islands of La Palma and Tenerife in the Canary Islands.
"Our experiment shows how mature 'quantum technologies' are today, and how useful they can be for practical applications," said team leader Anton Zeilinger in a statement. "The next step is satellite-based quantum teleportation, which should enable quantum communication on a global scale."
Quantum teleportation has been heralded as having enormous potential for sending un-hackable messages between quantum computers on a future quantum Internet. It uses the peculiarities of entangled quantum states in a pair of particles like photons to get around the limitations of the universe's "speed limit," the speed of light. If you change the quantum state of one entangled photon, it turns out, that change is instantly reflected in the other photon regardless of its physical distance from the transmitting, entangled particle.
What that means is that you could potentially send a message across the Solar System (or even the galaxy or the universe itself) and have it instantly appear in front of your recipient's eyes. Transmitting such a message by radio from Earth to Mars, for example, takes between three and 20 minutes to arrive, depending on the two planets' proximity at the time.
But there's a catch—at present, quantum teleportation isn't actually instantaneous for practical purposes. To start with, the Canary Island experiment didn't actually happen very recently. According to Alex Knapp of Forbes, the team pulled off its quantum teleportation feat last May but is only now publishing its findings in this week's issue of Nature.
That's just a housekeeping note, of course. The reasons for why practical applications of quantum teleportation take a bit more time than advertised are more complex.
First you have to get an entangled receiver photon out to where you want it to start receiving quantum teleported messages from the entangled transmitter photon that stays back at home. That outward trip is still restricted by the speed of light, meaning it's still going to take you several minutes at best to set up communication with Mars (or in the case of the Canary Islands experiment, the non-instantaneous amount of time it took to send the entangled receiver photon from one island to the other).
But you'd also need a physical facility on the Red Planet capable of housing your receiver photon safely. That would presumably have to be built on Earth and then shipped over several months to our neighboring planet via spacecraft.
Furthermore, it turns out that transporting an entangled photon over a distance without messing things up is an incredibly delicate task, which makes the accomplishment of the Canary Islands team remarkable even if the distance traveled seems pretty short.
"The realization of quantum teleportation over a distance of 143 kilometers has been a huge technological challenge," said team member Xiao-song Ma. The task involved several innovative new techniques developed to transmit an entangled photon wirelessly across "the turbulent atmosphere between the two islands" because using fiber optic cables was not a suitable option, the scientist added.
The gap between La Palma and Tenerife isn't tremendous, but the successful quantum teleportation experiment by physicists associated with the University of Vienna and the Austrian Academy of Sciences beat the previous record set by a Chinese research team by 46 kilometers. That doesn't mean the two quantum teleportation projects are at odds, according to Zeilinger, who is now aiming his sights on near-Earth orbit if not the stars.
"We have now taken a major step in this direction and will use our know-how in an international cooperation, which involves our colleagues at the Chinese Academy of Sciences. The goal is to launch a 'quantum satellite mission,'" he said.

/ 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.
