Weltmachtambitionen: Zu geringe Rechenleistung

Ihre Kommission werde Rahmenbedingungen für »einen großen Pool an nichtpersonalisierten Daten« schaffen, »der danach allen zur Verfügung steht«, teilte sie mit. So solle eine »European Open Science Cloud« eingerichtet werden, auf die auch Unternehmen Zugriff hätten.

He invented the web. Now he’s warning of a looming ‚digital dystopia‘

Ahead of a conference in Berlin Monday, Berners-Lee tweeted a warning of the risks faced.
He wrote: „If we fail to defend the free and open web, we risk a digital dystopia of entrenched inequality and abuse of rights.“
In an earlier statement on his foundation’s website, he called the web „one of the defining opportunities of our time,“ adding that collaborative action must be taken „to prevent the web being misused by those who want to exploit, divide and undermine.“

Research paper claims Google has achieved ‚quantum supremacy‘ – a milestone in computing after their quantum processor performed a ‚calculation in three minutes and 20 seconds that would take a state-of-the-art supercomputer 10,000 years‘

The technology carries major national security implications because quantum computers potentially could break traditional internet security programs or other codes.

Developing viable quantum computers has proved to be hugely challenging because they rely on superconductivity that can only be achieved in temperatures close to absolute zero.
Any instability in the qubits, for example from vibrations, can lead to ‘noise’ that causes calculation errors and undermines a quantum computer’s power to solve problems.

Earlier this month, IBM announced it was joining forces with a German research institute to explore the potential of quantum computing, backed by a government plan to invest $717million over two years in wider research in the field.

A claim by Google researchers that they performed the first quantum computation was briefly posted on a NASA website before being removed.
