Scientists Managed to Teleport Data over Three Meters with 100% Accuracy

Dutch scientists achieved accurate teleportation of quantum information over a distance of three meters. This is a great achievement, but is still far from the famous phrase “Beam me up, Scotty!” from Star Trek where people were teleported into space. However, it is another step in this direction. Many scientists now believe that once teleportation of people from one place to another will be possible. However, at present and for quite long time, we will be limited to teleportation of quantum information.

The evolution of this research will contribute to the creation of quantum Internet, which will interconnect lightning-fast quantum computers. Before the idea of quantum internet is realized, quantum teleportation will make data transfer more secure than in today’s communications, as the transmission of quantum data is considered 100% secure (at least theoretically). The study was conducted by researchers led by Professor Ronald Hanson of the Institute of Nanoscience Delft University of Technology in the Netherlands. They managed to teleport information encoded in subatomic particles between two points spaced three meters apart from each other with 100% accuracy.

Teleportation is based on the mysterious phenomenon of quantum entanglement, in which the state of a particle automatically affects the state of another distant particle. In the experiment, the entangled electrons were trapped within the diamond crystal at very low temperature. The researchers managed to teleport four different states of subatomic particles, each corresponding to a unit of quantum information (qubit) – equivalent to the conventional unit of digital information (bit). A key goal of the scientists is to create a powerful quantum computer able to work with a large number of entangled quantum units of information (qubits). The achievement is published in the journal «Science». Hanson argues that the laws of physics do not prohibit teleporting large objects, and therefore human beings. He thinks that someday in the distant future it will be possible to teleport people even into space, just like in the Star Trek.

Quantum Physicists Have Successfully Teleported A Qutrit For The Very First Time

Quantum teleportation has been a term related to qubits for the longest time and recently, researchers have successfully teleported ‘qutrits’. The research published on American Physical Society is a major breakthrough that will propel the quantum computation prowess to incredibly faster speeds.

Scientists have been able to teleport qubits, Quantum Bits of information that have binary states – 0 or 1 – but qutrits have three possible states – 0, 1 and 2. Qubits and qutrits have the property of being able to exist in multiple states at the same time, i.e. superposition which allows for amazing applications in quantum computing.

Quantum Teleportation is based on quantum entanglement, through which the properties of a quantum particle can be transferred to a distant particle without physical movement of the particle itself. It is nothing like the ‘Warp Speed’ or ‘Warp Drive’ that has been popularized in sci-fi but rather, it is just two interlinked particles revealing the properties of the other particle. Quantum teleportation is possible by using photons which carry the quantum information about the two possible states in case of qubits or three possible states as in qutrits.

Splitting the photon into three beams through the use of an intricate contraption consisting of calibrated setup of lasers, beam splitters and barium boratecrystals, the researcher created their qutrits. They also said that it could be possible to use ququarts in the future. With 0.75 fidelity over 12 states of entanglement, the researchers were able to prove that qutrit teleportation is possible.

The research will surely propel the quantum technology to the next level as quantum teleportation is an integral part of quantum computing applications.

“Thousands of Solar Reflector Satellites” Could Warm Up Mars

Space Retreat

Since 2015, SpaceX CEO Elon Musk has made it abundantly clear that he really wants to nuke Mars in order to terraform it — and, presumably, turn it into a habitable space retreat for billionaires.

But he might have a plan B up his sleeve that wouldn’t risk turning the Red Planet into a gigantic planet-sized Chernobyl.

“Might make sense to have thousands of solar reflector satellites to warm Mars versus artificial suns,” Musk tweeted on Tuesday. Then he added, cautiously: “TBD.”

Martian Mirrors

That idea might not be as crazy as it sounds: using orbital mirrors to terraform Mars was suggested by University of Arizona undergrad Rigel Woida back in 2006 — a suggestion that won him a NASA fellowship at the time.

According to Woida’s paper from 2007, the idea was to have a “network of two to three hundred, 150 meter diameter reflectors in monolith form or a series of small clustered groups” to warm the Martian surface.

Artificial Suns

Musk also elaborated on his Plan A — “nuke Mars” — on Twitter: drop a “continuous stream of very low fallout nuclear fusion explosions above the atmosphere to create artificial suns.” After all, the Sun is technically an “immense thermonuclear explosion” itself, as he explained last week.

But for that to ever happen, NASA would have to change its stance on the matter. Just over a year ago, NASA research found that nuking Mars wouldn’t be enough to turn it into an Earth-like holiday destination.

We Have a Cure for the Deadliest Form of Tuberculosis

The Food and Drug Administration just approved the third and final part of a new drug regimen shown to cure the deadliest strain of tuberculosis.

The regimen involves taking five pills every day for six months straight, but that’s nothing compared to the existing treatment, which requires 40 daily pills for two years, according to The New York Times. And in a small clinical trial, the new treatment was shown to cure the rare, deadly XDR strain of tuberculosis in 90 percent of people, suggesting that the disease could soon become much more manageable.

Tuberculosis is still a major problem in a large chunk of the world. The disease is the most common infectious cause of death on Earth, the NYT writes, and the XDR strain had already built up a resistance to all four types of antibiotics that doctors currently use to treat it.

Ten million people catch XDR tuberculosis every year. Three-quarters of those people die before they get any treatment, per the NYT, and existing cures only worked on just over a third of the remainders.

The new treatment requires three separate drugs, the newest of which just got FDA approval. Gerald Friedland, one of the scientists who discovered the XDR strain told the NYT that he thought the recent experiment was “a wonderful trial.”

“If this works as well as it seems to,” he said, “we need to do this now.”
