The place are the Worldwide Quantum Networking Testbeds?

By Amina Bashir and Doug Finke

One of many key purposes of quantum know-how is to create a quantum community that may talk messages and quantum states in a manner that offers them extra safety and different properties as a result of legal guidelines of physics. Though this analysis continues to be very early, plenty of organizations have began to create quantum testbeds to check out these quantum networks to be able to proceed creating them and advancing the know-how. Most of those testbeds are used for Quantum Key Distribution, which one may argue as the only software for a quantum community. Nevertheless, in a while there could be a vary of latest purposes together with quantum sensor networks, distributed quantum computing, and blind quantum computing which might be extra advanced, and may deliver fully new capabilities.

To get a deal with on the testing that is occurring, we curated an inventory of all public mentions of quantum community testbed exercise happening worldwide to point out the scope of the exercise and the place it’s taking place. We must always say that this analysis could be very dynamic, and our itemizing is simply a snapshot of a second in time, so there could also be some modifications after we publish this. We welcome any feedback or updates from individuals concerned with these initiatives.

The desk beneath reveals an inventory of 44 testbeds that we discovered together with a hyperlink to an outline of them accessible on the web together with the nation they’re situated in and our greatest willpower of the standing. Notably, a few of these testbeds could have been created just for short-term use and should have already been retired. A few of them could have been introduced and are beneath development. Within the desk beneath, we’ve famous each these instances if we understand it.

For extra particulars about quantum networking typically, you may get hold of a report written by World Quantum Intelligence titled Quantum Protected Outlook that gives extra technical particulars on quantum networking in addition to the software program primarily based Submit Quantum Cryptography (PQC), which is one other method to offering encryption that’s protected from quantum laptop primarily based assaults.
