It may not lead to Star Trek teleportation, but researchers have revealed a major breakthrough in quantum teleportation.
Researchers succeeded in teleporting information about the quantum state of a photon, a particle of light, over 15.5 miles (25 kilometers) of optical fiber to a crystal ‘memory bank,’ setting a new record of distance traveled in this manner.
The research could have implications for cryptography, which involves transmitting information securely, including communications between Earth and spacecraft.
The new research co-authored by Francesco Marsili, microdevices engineer at NASA’s Jet Propulsion Laboratory, Pasadena, California, makes use of this phenomenon in a technological advancement published in the journal Nature Photonics.
The previous record in optical fiber was 3.7 miles (6 kilometers).
This complex phenomenon is called ‘quantum teleportation.’
The research could have implications for cryptography, which involves transmitting information securely, including communications between Earth and spacecraft.
‘We can imprint the state of a system on another system, even when the two are far apart,’ Marsili said.
‘Using this effect in communications could help in building an intrinsically secure space communication network — i.e., communication channels that cannot be hacked.’
