Quantropi safely distributes real random numbers over large distances

Quantropi safely distributes real random numbers over large distances-01

Quantropi, Inc., a Canadian provider of quantum security solutions, today announced the impressive results of a high-level demonstration of its proprietary SEQUR ™ Quantum Entropy as a technology. Service (Quantum Entropy as a Service), in which strong random keys were created and then encrypted and distributed with quantum security around the world, via today’s Internet. The demonstration was conducted by CANARIE, the federal partner of Canada’s National Research and Education Network (NREN), and its Alberta partner , Cybera. CANARIE’s participation in the demonstration leveraged existing network infrastructure to support the Quantropi solution and the evolution of the Canadian quantum ecosystem.

The results point to a radical change in capacity compared to the prevailing quantum key distribution (QKD) methods.

The deployed configuration originated from the QiSpace ™ Cloud server in Ottawa (Canada) and involved the transmission of quantum entropy to Edmonton (Canada), and then to San Francisco and New York (United States), London and Frankfurt (Europe), for finish almost 15,000 kilometers away, in Singapore.

The demo achieved speeds of megabits per second, up to 100 Mbps in Edmonton . Here you can see a full comparative graph of the performance.

“Let’s take these results to the corporate world,” said Michael Redding , Quantropi’s chief technology officer. “If a 32-byte AES key is the standard, we are transmitting from just under 400,000 ( Edmonton ) to 55,000 keys per second (Singapore). To understand this, Google – which represents ten times the traffic of any other site on the planet – requires about 64,000 32-byte keys per second. Therefore, only from our small beta server in Ottawa – prior to optimization – we can support between one and six Google keys per second. With each of the keys delivered as secure against to any attack – classical or quantum. ”

“Now compare that performance to the conventional QKD,” continued Redding. “At 20 kilometers, QKD can reach about 10 megabits, that is, half Google; that is already less than what we achieved at 15,000 kilometers. And beyond 100 kilometers, QKD reaches zero; it cannot work. Therefore, what we are demonstrating here is a radical alteration, by securely distributing quantum keys over enormous distances, on any network. And that’s a game changer. ”
