Quantropi makes history by quantum-securely distributing true random numbers over vast distances using existing network infrastructure
The results signal a radical shift in capability as compared to prevailing Quantum Key Distribution (QKD) methods.
The deployed configuration originated with the QiSpace™ Cloud server in Ottawa, Canada , and involved transmitting quantum entropy to Edmonton, Canada , and then to San Francisco and New York in the USA , London and Frankfurt in Europe , and finally ended almost 15,000 kilometers away in Singapore .
The demonstration achieved speeds in the megabits per second – as high as 100 Mbps to Edmonton . A complete comparative summary performance chart can be viewed here.
"Let's translate these results to the business world," said Michael Redding , CTO of Quantropi. "If a 32-byte AES key is the standard, we're transmitting anywhere from just under 400,000 ( Edmonton ) down to 55,000 keys per second ( Singapore ). To get your head around this, Google – representing ten times the traffic of any other site on the planet – requires an estimated 64,000 32-byte keys per second. So just from our small beta server in Ottawa – pre-optimization – we can support anywhere in the neighborhood of one to six Googles per second. With every single key delivered as secure from any attack – classical or quantum."
"Now compare that performance to conventional QKD," Mr. Redding continued. "At 20 kilometres QKD can get to roughly 10 megabits, or half a Google – that's already less than what we achieve at 15,000 kilometres. And beyond 100 kilometres QKD goes to zero; it cannot operate. So, what we are demonstrating here is a radical disruption, by quantum-securely distributing keys across huge distances, over any network. And that's a game changer."
