Quantensprung: In Ehningen wird Europas erster kommerzieller Quantencomputer vorgestellt

(heute)

In Ehningen (Kreis Böblingen) wird am Nachmittag der erste kommerzielle Quantencomputer Europas eingeweiht. Bundeskanzlerin Angela Merkel (CDU) wohnt dem Festakt online bei. Das Projekt geht auf ein Gespräch zwischen Merkel und IBM-Chefin Ginni Rometty am Rande des Weltwirtschaftsforums in Davos zurück: …

ZITiS baut Supercomputer zur Entschlüsselung

(16.10.2018)

Dieser Supercomputer hat „höchste Priorität“ für die ZITiS-Abnehmer Verfassungsschutz, Bundeskriminalamt und Bundespolizei.

Vor zwei Wochen wurde bekannt, dass ZITiS auch einen Quantencomputer einsetzen will. Ob Supercomputer und Quantencomputer verschiedene Projekte sind, will ZITiS auf Anfrage nicht verraten:

IBM now has 18 quantum computers in its fleet of weird machines

(May 6, 2020)

Eighteen quantum computers might not sound like a lot. But given that each one is an unwieldy device chilled within a fraction of a degree above absolute zero and operated by Ph.D. researchers, it’s actually a pretty large fleet. In comparison, Google’s quantum computers lab near Santa Barbara, California, has only five machines, and Honeywell only has six quantum computers.

Quantum leap: why the next wave of computers will change the world

(29 Oct 2019)

To break a widely used RSA 2048-bit encryption, a classical computer with one trillion operations per second would need around 300 trillion years. This is such a long time that we all feel very safe.

A quantum computer using Shor’s algorithm could achieve the same feat in just 10 seconds, with a modest 1 million operations per second. That’s the power of quantum computers: 300 trillion years versus 10 seconds.

Physik: Neuer magnetoelektrischer Effekt entdeckt

Durch die gestörte Symmetrie ist es möglich, die sogenannte elektrische Polarisation des Kristalls mit einem Magnetfeld zu verändern. Dabei ist nicht nur die Stärke des Magnetfeldes entscheidend, sondern auch dessen Richtung. „Wenn man die Richtung des Magnetfelds ein kleines bisschen dreht, kann die Polarisation völlig umkippen. Das ist eine neue Form des magnetoelektrischen Effekts, die man bisher noch nicht kannte“, erklärte der Physiker.

Trump administration establishes $75 million quantum computing centers

The center set to be established at the University of California Berkeley will address present and future quantum computing, while the center at the University of Illinois will focus on hybrid quantum architecture and networks. The third institute, at the University of Colorado, will look into the development of quantum sensors to help with more precise measurements across a variety of fields.

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‘

(22.09.2019)

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.
