Our AQTION partners at TOPTICA published an article in LaserFocusWorld. It is titled “Lasers shape the world of quantum technologies” and you can find it here.
Welcome Lorenzo Cardarelli!
Lorenzo completed his PhD at the University of Hannover, Germany, where he investigated quantum link models and topological phases in cold atom systems. At Aachen and Jülich he is joining the EU Quantum Technology Flagship AQTION project, where he hopes to deploy his expertise in AMO physics and the study of strongly correlated systems to contribute to the development and applications for Europe’s first compact trapped-ion quantum computer demonstrator.
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.
David Amaro, Markus Müller and Amit Kumar Pal developed new and experimentally feasible protocols to characterise entanglement in noisy quantum computers, published in New J. Phys. 22, 053038 (2020)
– we invite you to also have a look at the video abstract.
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.
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.
David Amaro and Markus Müller developed new entanglement witnesses. In their work published in Phys. Rev. A 101, 012317 (2020), they theoretically establish the noise tolerance of the proposed witnesses and benchmark their practical performance by analyzing the local entanglement structure of an experimental seven-qubit quantum error correction code realised by the Innsbruck team.
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.
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).
Congratulations, Markus Müller! Markus starts a professorship (W2) for theoretical quantum technology at RWTH Aachen University and Forschungszentrum Jülich, Germany, relocating from Swansea University (UK) with his research team. Click here to visit his group website.
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.
Rainer Blatt is awarded the Micius Prize which is presented for the first time this year by The Chinese Micius Quantum Foundation to promote outstanding research in quantum physics. Rainer receives the prize for his pioneering experiments that demonstrated fundamental elements of quantum computing with trapped ions. For more information, have a look at the IQOQI news release.
