This is not the same as " classical " teleportation akin to Star Trek . Just to get that out of the way overnice and early .
scientist saythey have set a new space record for quantum teleportation , which could be important in term of quantum computation , but plausibly less so in beaming yourself to a ballistic capsule . So , what is quantum teleportation ? Let ’s take a look .
The term " teleportation " is admittedly a bit of a misnomer , although it is the condition used by scientists . Quantum teleportationis fundamentally the transferee of entropy relating to a photon across large aloofness . It involve reconstruct the quantum state – set of info – of a photon in a unlike location . In this instance , the information was transported across 102 kilometers ( 63 miles ) of opthalmic fiber , four times further than antecedently potential . For a more detailed verbal description of how it works , check out ourprevious articleon the last record .
In this latest breakthrough at the National Institute of Standards and Technology ( NIST ) lab in Colorado , the investigator used new individual - photon detector to increase the space of quantum teleportation . Only 1 % of photons make it all the way down the fiber , so the sensor must be extremely sensitive . In this study , they were able-bodied to record more than 80 % of incoming photon ; previously , fiber transmission result in too great a departure of quantum data point , making teleportation over foresightful distances impossible . " We never could have done this experiment without these raw detectors , which can measure this incredibly weak signal , " say NIST ’s Marty Stevens in astatement .
The research , put out in the journalOptica , also described how this technique could be used to make " quantum repeating firearm , " repeatedly sending the data to allow for greater distances . This could be one step towards a high - hurrying and radical - encrypted quantum Internet .
Now the researchers want to up the rate of teleportation in photons ; currently , the effect only fall out in 25 % of transmission . It ’s a long way to go until this technique becomes in truth utile , but it ’s a start at least .
