This might be the openhanded tech humblebrag ever . A squad of scientist at Los Alamos National Labs has quietly shrugged its berm and admitted to the fact that , yeah , it ’s been using quantum internetfor , like , the last two days . Whatever .
Steady on there , cowboy ! If you ’re not intimate with the concept of a quantum internet , then you should be . The aspiration of many a security measures expert , it ’s a concept that uses the laws of quantum mechanics to make perfectly safe online communication . The idea is that measuring a equipment characteristic of a quantum objective — like a photon — always changes it , so attempts to intercept message screws them up and renders them incomprehensible .
job is , most quantum internet solutions only give up messages to be transmit between two location , and not rout elsewhere . That ’s because working out where it ’s supposed to be routed modification the land of the quantum message and turns it into rubble .
But the team from Los Alamos National Labs in New Mexico has revealed that it has a dissimilar kind of quantum internet — that it ’s been using for the preceding two year . Technology Reviewdescribes how it works :
Their approach is to create a quantum connection base around a hub and spoke - type web . All messages get routed from any degree in the net to another via this central hub … The approximation is that messages to the hub rely on the common grade of quantum security . However , once at the hub , they are convert to established classical bits and then reconvert into quantum flake to be transmit on the 2d leg of their journeying . So as long as the hub is unattackable , then the net should also be dependable .
While that technique could be blockade by scalability , the team claims to have overwhelm that problem by equipping each node in the web with quantum sender , but not sensor . With only the hub equal to of receiving quantum messages , it bring one - fourth dimension messages from nodes which it uses to arrange up secure data transfer via a normal net protocol .
The solvent is n’t of necessity true quantum cyberspace — but it offers a comparable spirit level of protection . And you bonk , has worked for two geezerhood . The only issue , of course , is the security measure of that central hub — and it stay on to be seen whether that centralized power point of risk will discontinue the Los Alamos solution hitting the mainstream .
