Is there a better system? Maybe it is the best it can be. Or not perfect still. But still it is not possible to catch every single injustice and innocents pay the price instead of the guilty. It needs improvement towards this way but it seems economy limits everything. At least there is some form of peace, people who smile, evolution, products that make life easier. But what moral person can enjoy the joys of life when justice is wrong?

Some people do not want to have sex and consider it rape. However, the system's people they all want sex. The system should keep the people in the system. The system should be just. They consider them innocent and the others guilty. But how. They all pretend to be the exact opposite and create fake evidence for the innocents.

There must be a way to reverse the lies. But it seems that people are made to think this way that once they shape an opinion about someone or something it is very difficult to change it especially for the opposite unless a big issue occurs. And even if they want to do that, if they are part of a system, the system forces them to follow the trend of condemning so as to not exclude them.

Only the guilty survive nowadays and present themselves as innocents in the media. And they make you consider the innocents as guilty. Fascistic! The only way to fix this is to consider the guilty as innocents and the innocents as guilty. The fame is always innocent. Fame is always covered.

35 years ago, Jim Sanborn presented the cryptographic sculpture Kryptos to the Central Intelligence Agency in Langley, Virginia. Made from copper, granite, quartz and petrified wood, it has four sections, each of which holds a message in code. Over the years, three of the sections have been solved — by CIA code breakers, a California computer scientist, and the National Security Agency. Now, 79-year-old Sanborn says he's going to auction off the solution to the final message, with the company arranging the sale estimating a winning bid between $300,000 and $500,000. Here's @newyorktimes's story on why he's doing it now, and what he hopes the winning bidder will do with the secret.

The paper I co-authored (“A Critical Analysis of Deployed Use Cases for Quantum Key Distribution and Comparison with Post-Quantum Cryptography”) was accepted for publication by “EPJ Quantum Technology” today. 😊

You can find the preprint here, Nick will eventually update it with the final changes.

In short: We looked into existing use-cases for #QuantumKeyDistribution and whether they make any sense and did so as a joint team between people with a QKD-background and cryptographers who started out very critical of QKD. (I’m firmly in the latter camp.)

My personal summary (though some of my co-authors won’t share it to this extend): #QKD is bullshit and not useful for practical purposes as it stands.
