Quantum computers by AQT and University of Innsbruck leverage Cirq for quantum algorithm development


Quantum computers promise to solve problems that are out of reach for today's supercomputers. Programming quantum computers differs radically from what programmers are used today and thus new programming languages are required. A collaborative effort by Alpine Quantum Technologies (AQT) and the University of Innsbruck allows direct access to the ion-trap quantum computer in Innsbruck via Cirq, a framework developed by Google focused on developing and implementing quantum algorithms. Cirq can be used to explore quantum algorithms on the different hardware architectures, superconducting electronics and trapped ions.

Several research facilities and companies are working on the realisation of quantum computers. There are multiple physical platforms that might host a future quantum computer, where AQT pursues trapped ions and Google is following an approach based on superconducting electronics.

Each approach has different capabilities and limitations, generally reflected in different programming languages dependent on the device. This mix of program languages makes it hard for software engineers and programmers to use these quantum computer prototypes as well as to explore the capabilities of different architectures.

Quantum Innsbruck and Quantum Munich

Google developed a Python framework. called Cirq for creating, editing, and invoking Noisy Intermediate Scale Quantum (NISQ) circuits Dr. Markus Hoffmann from Google Munich explains “It's great to see the adoption of Cirq following the spirit of the Apache 2.0 open source license and making further hardware platforms accessible to the Cirq developer community.”

The library supports multiple hardware architectures, based on superconducting electronics and atomic systems. Now, researchers and industry partners can readily run their quantum software on the Innsbruck quantum computers and also enable students to build out expertise on running quantum algorithms on actual hardware. Besides research, these efforts also benefit the quantum computer startup AQT in Austria.

CEO Dr. Thomas Monz “is delighted to provide such a simple and effective interface between international quantum software developers and our Innsbruck-based quantum computer infrastructure to facilitate the realization of an entire suite of quantum apps for research and industry partners.” Dr. Philipp Schindler at the University of Innsbruck is convinced that the interface will enable new collaborations with research partners around the world.

About AQT:
AQT is a quantum computer startup located in Innsbruck, building on decades of experimental and theoretical expertise in the field of quantum information processing. The goal of AQT is to get quantum technologies out of a laboratory environment and turn these technologies into everyday-products. The long-term goal is a quantum computer based on trapped ions that can be readily operated from any PC or laptop.

About University of Innsbruck:
The work groups at the University of Innsbruck are, amongst other efforts, performing research on clocks, sensors, simulators and quantum computers with ion traps. Together with the Austrian Academy of Sciences, the University of Innsbruck is an internationally recognized center for quantum research.

Im Focus: A cavity leads to a strong interaction between light and matter

Researchers have succeeded in creating an efficient quantum-mechanical light-matter interface using a microscopic cavity. Within this cavity, a single photon is emitted and absorbed up to 10 times by an artificial atom. This opens up new prospects for quantum technology, report physicists at the University of Basel and Ruhr-University Bochum in the journal Nature.

Quantum physics describes photons as light particles. Achieving an interaction between a single photon and a single atom is a huge challenge due to the tiny...

Im Focus: Solving the mystery of quantum light in thin layers

A very special kind of light is emitted by tungsten diselenide layers. The reason for this has been unclear. Now an explanation has been found at TU Wien (Vienna)

It is an exotic phenomenon that nobody was able to explain for years: when energy is supplied to a thin layer of the material tungsten diselenide, it begins to...

Im Focus: An ultrafast glimpse of the photochemistry of the atmosphere

Researchers at Ludwig-Maximilians-Universitaet (LMU) in Munich have explored the initial consequences of the interaction of light with molecules on the surface of nanoscopic aerosols.

The nanocosmos is constantly in motion. All natural processes are ultimately determined by the interplay between radiation and matter. Light strikes particles...

Im Focus: Shaping nanoparticles for improved quantum information technology

Particles that are mere nanometers in size are at the forefront of scientific research today. They come in many different shapes: rods, spheres, cubes, vesicles, S-shaped worms and even donut-like rings. What makes them worthy of scientific study is that, being so tiny, they exhibit quantum mechanical properties not possible with larger objects.

Researchers at the Center for Nanoscale Materials (CNM), a U.S. Department of Energy (DOE) Office of Science User Facility located at DOE's Argonne National...

Im Focus: Novel Material for Shipbuilding

A new research project at the TH Mittelhessen focusses on the development of a novel light weight design concept for leisure boats and yachts. Professor Stephan Marzi from the THM Institute of Mechanics and Materials collaborates with Krake Catamarane, which is a shipyard located in Apolda, Thuringia.

The project is set up in an international cooperation with Professor Anders Biel from Karlstad University in Sweden and the Swedish company Lamera from...
