Website has new updates, I'll start with Mr Kuroobi(Mr Black Belt):

Spoiler for Mr Black Belt:

Mr Kuroobi

Originally a robot found by Sakura in a scrapyard and was repaired.
It was a 4th generation autnomous walking robot from the Earth's golden ages, but the Genius Sakura installed latest shields, actuators and other devices, along with highly advanced Martial Arts Programs to modify it into a multi-purpose Bodyguard Robot.

Favourite line: Tomodachi ni narimashou (Let's be friends)
When happy: Gottsuan desu (not sure what this is but its hilarious lol)

Next we finally have the answer to QT and makes things clearer:

Spoiler for QT:

The power that allows your imagination to interfere with reality. The power of images. The power than is formed by your imagination.
※Telesis (Progress that is intelligently planned and directed) : the attainment of desired ends by the application of intelligent human effort to the means.
(The Japanese there is exactly the same as what I found in webster dictionary, so copypasta)

QT is the disposition that allows one to interact with QT-ARMS. QT-users can move QT-ARMS with their powerful thoughts. A device called QT-Amplifier is used to stabilise and allow continuous manifestation of their QT.

Regarding one's disposition of QT, it can be easily checked through blood samples and reaction to QT tests, but you must be registered by the government as a QT-user.

However, the use of QT-Amplifiers are restricted only to military weapons, normal civilians are not alloweed to possess and use QT abilities.(For this reason, the existance of QTs are largely unknown to the public). ICP's pilots are some of the few exemptions.

Spoiler for QET:

Quantum Engineering Technology

It originated from the Shishidou Group's technological development in Nano Technology, which in the distant past have advanced to become QET that is applicable at an industrial level.

QET is said to be a breakthrough in human civilisation, it allowed previously unimaginable advanced technologies to be made possible.

The battle between energy and materials was solved in an instant, the obstacles for space travel and colonisation, mass production of colonies and transportation of billions using space ships were solved, it allowed humans to officially enter the space colonisation age.

At first it was the Shishidou Group that monopolised the industries with QET, but slowly other industries picked up. For that, QET became a common technology in everyday life. But it still doesn't shake the Shishidou Group from its place as the leading complany that originally came up with QET development, the company has since become the largest and most powerful enterprise in human history.

The subject of QT should be quite clear now and everything makes good sense.
