An ion-trap quantum computer for Europe. Research project funded by the Quantum Technology Flagship

Trapped ion quantum computing turns 25. On 15 May 1995, Ignacio Cirac and Peter Zoller published the first conception of how to actually build a quantum computer in Physical Review Letters. In this seminal paper, they showed that laser-cooled atomic ions, trapped in a vacuum, could be used as qubits with which elementary quantum logic operations could be performed. The Cirac–Zoller paper turned quantum computing from a bold theoretical idea into an experimental race to build an actual device. A race that we are very happy to be part of. On the occasion of this anniversary, Nature Reviews dedicated a highlight article to the paper.

Our first results on high-fidelity entanglement between remote quantum processors are now published in PRL. The AQTION team from the University of Oxford has demonstrated high-fidelity and high-rate entanglement between two ion-trap based quantum computers separated by a couple of meters. This is an important step towards the realization of modular quantum computation. You can find the publication here.

The AQTION team at Johannes Gutenberg University Mainz just published a new paper on shuttling-based trapped-ion quantum information processing in AVS Quantum Science. Click here to check it out.


January 2020
With the help of AQTION, a new version of QuEST was released. QuEST, which stands for Quantum Exact Simulation Toolkit, is a system for using conventional computers to mimic the behaviour of small quantum computers (up to about 40 qubits). There are several such emulators, but QuEST is exceptional in the depth and breadth of its hardware support: it’s multithreaded, distributed and GPU accelerated, so that it can make good use of practically any system. The recently released version 3.0 dramatically increases the supported features — it adds the powerful ability to simulate multi-qubit multi-controlled general unitaries and Kraus maps. In practice this means that pretty much any kind of quantum computer, with practically any kind of realistic environmental noise, can be explored with QuEST. Click here to learn more.

We are thrilled to share that Rainer Blatt is a listed among the most “Highly Cited Researchers 2019” by Clarivate Analytics and the Web of Science Group. The list recognizes the world’s most influential researchers of the past decade, demonstrated by the production of multiple highly-cited papers that rank in the top 1% by citations for field and year in Web of Science.


November 2019
Good news for quantum developers: Our ion trap quantum computer now supports Qiskit, a prominent open-source quantum programming language initially created by IBM and developed by scientist all around the world. Qiskit comes with a wide range of algorithms and applications, which will now be available via the cloud on the Innsbruck quantum devices. For more information, please check out this press release by the University of Innsbruck (German only).


September 2019
We are delighted to announce that quantum algorithm developers can now have direct access to our ion trap quantum computer in Innsbruck via Google’s framework Cirq. Check out this press release by the University of Innsbruck for more information.
