Scientists in China teleport first object 300 miles into space!
New Delhi: Terrestrial and space experiments are carried out around the world. With the race to reach zenith ever stronger by the second, innovative strategies to achieve the same are deployed by space agencies around the world.
In the most recent development, Chinese researchers have successfully teleported a photon with Earth’s orbit.
The photon has traveled all the way from the Gobi desert to a satellite under the name ‘Micius’, in orbit 500km in total.
Researchers owe their success to quantum entanglement, a process in which two particles react as no physical connection exists between them.
According to the Deccan Chronicle, “Micius” is described as a high sensitivity image receiver that is equipped with the ability to detect single photon quantum states thrown from the ground.
The satellite was developed to allow scientists to test with quantum entanglement, cryptography and teleportation.
“Long-distance teletransport has been recognized as a key element in protocols such as quantum networks and distributed large-scale quantum computing,” said the Chinese team in the MIT Technology Review.
“Past experience teleportation between distant places is limited to a distance of about 100 km due to the loss of photons in optical fibers or free terrestrial channels,” said Deccan Chronicle.
Quantum teleportation could be exploited to produce a new form of communication network, in which information is encoded in quantum states entangled photons, rather than strings of 0s and 1s.
The huge safety advantage would be that it would be impossible for a listener to measure photon states without disturbing them and revealing their presence.
According to The Guardian, Ian Walmsley, professor of experimental physics Hooke at Oxford University, said the latest work was an impressive step to fulfill this aspiration.
“This indicates palpably that the field is not limited to the scientists sitting in their laboratories thinking about strange things. Quantum phenomena actually serve a purpose and can really bring important new technologies.”
The advantage of using a satellite is that it particles light through space for much of your trip. Last month, the Chinese team has shown to send interwoven photons from space to Earth.
The latest work done the opposite: they sent photons from the base of the mountain to the satellite as it passed directly overhead, he told The Guardian.
At present, many similar analog satellites are being developed by various teams, including the European Space Agency and Canadian scientists. However, the latest results suggest that China opens the field.
