One of the most infuriating things about #QuantumComputing related stuff is that #QuantumComputers being theoretically able to break factoring and DLog (aka: most asymmetric crypto in current use) using Shor’s algorithm is used as a selling point for #QuantumCryptography (QC) or #QuantumKeyDistribution (#QKD).

The two topics really have nothing to do with each other, the solution for dealing with the broken schemes is to replace them with non-broken ones.

If we want QKD, there has to be a DIFFERENT motivation for it, that has nothing to do with Shor’s algorithm.

Somehow we have allowed the presentation to become “after classical crypto choose #PostQuantumCrypto (#PQC) or QKD”, instead of “keep using classical crypto that is secure against known attacks or switch to QKD”.

In line with that we should also increasingly move to stop talking about PQC, and just talk about secure #cryptography, because that is really all it is.

GÉANT, Toshiba Europe Ltd, PSNC and the Anglia Ruskin University announce the first demonstration of #QuantumKeyDistribution using telecoms standard equipment and infrastructure.

The experiment was conducted in Germany, with access to the #network infrastructure provided by #GÉANT. Communication was established over a link spanning 253.9 km between Frankfurt and Kehl with a 56.0 dB loss and a relay in Kirchfeld.

GÉANT Network - The GÉANT Network - Serving the R&E Community · Toshiba Europe, GÉANT, PSNC and Anglia Ruskin University announce the first demonstration of Quantum Key Distribution within commercial telecommunication networks. - GÉANT NetworkQuantum communications harness quantum phenomena like superposition and entanglement to enhance information transfer between remote nodes. The key benefits of these techniques are the ability to be able to detect if communications have been intercepted or modified en-route. Which makes these techniques ideal for highly sensitive data interchange. However, coherent quantum communications, essential for typically

A new #GÉANTInfoshare on 17 July will cover recent experiences within our community with long-distance #QuantumKeyDistribution (#QKD) #network trials: events.geant.org/event/1675

In one of the experiments three different QKD testbeds were interconnected across Spain, Germany & Poland as part of #OPENQKD

The second work describes the recent collaboration btw. #Toshiba & GÉANT on a long-distance #Quantum Cryptography experiment, conducted over a 254km network testbed by GÉANT, from Frankfurt to Kehl

When physicists promote Quantum Key Distribution (#QKD) systems, they tend to claim things like: “it is unbreakable because of the laws of quantum physics”

The @bsi has a great report on why that's not true, and that these systems are also vulnerable to many possible implementation attacks.
