A roadmap for the long run orientation of quantum simulation has been established in a write-up co-authored at the University of Strathclyde.
Quantum computers are extremely powerful devices with a capacity for speed and computation far beyond the reach of classical or binary computing. Instead of a binary system of zeros and ones, it works by superpositions, which can be zeros, ones or both at the same time.
The constant development Quantum computing evolution has reached the point of having an advantage over classical computers for an artificial problem. It could have future applications in a wide variety of fields. A promising class of problems involves the simulation of quantum systems, with potential purposes such as the development of materials for batteries, industrial catalysis and nitrogen fixation.
The article, published in Mother nature, explores the near- and medium-term possibilities of quantum simulation on analog and digital platforms to help assess the potential of this field. It was co-authored by researchers from Strathclyde, the Max Planck Institute for Quantum Optics, the Ludwig Maximilians University of Munich, the Munich Center for Quantum Science and Technology, the University of Innsbruck, from the Institute for Quantum Optics and Quantum Information of the Austrian Academy. of Science and Microsoft Company.
Professor Andrew Daley, Department of Physics, Strathclyde, is the lead author of the paper. He said: “There have been many exciting advances in analog and digital quantum simulation in recent years, and quantum simulation is one of the most promising areas of quantum information processing. It is already quite experienced, both in terms of algorithm development, and in the availability of significantly advanced analog quantum simulation experiments on an international scale.
“ In the history of computing, classic analog computing and digital computing have coexisted for more than half a century, with a gradual transition to digital computing, and we expect the same happen with the emergence of quantum simulation.
“As the next step in the development of this technology, it is now crucial to discuss the “practical quantum advantage” , the point at which quantum devices will solve problems of practical interest that are not tractable for traditional supercomputers.
“Many of the most promising short-term applications of quantum computers fall under simulation. quantum ion: modeling the quantum properties of microscopic particles that are directly relevant to understanding modern materials science, high energy physics and quantum chemistry.
“Quantum simulation should be possible in the future on fault-tolerant digital quantum computers with more flexibility and precision, but it can also already be performed today for specific models thanks to special analog quantum simulators. This occurs analogously to the study of aerodynamics, which can be conducted either in a wind tunnel or through simulations on a digital computer. Where aerodynamics often uses a smaller scale model to understand something big, analog quantum simulators often use a larger scale model to understand something even smaller.
“Analog quantum simulators are now moving from providing qualitative demonstrations of physical phenomena to providing quantitative alternatives to native problems. A particularly interesting short-term path is the development of a range of hybrid programmable quantum simulators between digital and analog techniques. automotive potential it merges the best advantages of both sides by using native analog operations to produce highly entangled states.”
as well as the development of platforms for analog quantum simulation and digital quantum computing. The partners collaborated in the framework of the Horizon project 2020 EU Quantum Systems Flagship PASQuanS. At Strathclyde, research in this area is strongly integrated into the UK’s national quantum technology program and has received substantial funding from United kingdom Analysis and Innovation.
A technology cluster Quantum is part of the Glasgow City Innovation District, an initiative led by Strathclyde with Glasgow City Council, Scottish Company, Entrepreneurial Scotland and the Glasgow Chamber of Commerce. It is envisioned as a global location for quantum industrialization, attracting companies to locate, accelerate growth, improve productivity and access world-class research technology and skills in Strathclyde.
The University of Strathclyde is the only university establishment to have been a partner of the four quantum technology hubs funded by the EPSRC in both rounds of funding. The Hubs are in: Sensing and Timing Quantum Enhanced Imaging Quantum Computing and Simulation and Quantum Communication Systems.
