Obiettivo del progetto (Objective)
'Scientists are beginning to achieve a level of control over quantum systems in the laboratory required to use them to predict the behaviour of other quantum systems i.e. to perform quantum simulations. This has the potential to solve problems of fundamental importance in many fields of research and technology. In this document I present a research proposal in the field of experimental quantum simulation, to be carried out in a trapped-ion system at the Institute for Quantum Optics and Quantum Information in Innsbruck, Austria. The central objective is to develop and apply the first universal quantum simulator, building on the world leading ion-trap expertise in Innsbruck. This will be achieved in three steps: completing the set of operations and techniques required for a universal simulation toolbox; building a new ion trap that will enable coherent control over more than 10 ions; applying this technology to perform the most advanced quantum simulations to date. These all represent important next steps in the young, multi-disciplinary field of quantum simulation. Through my research in Australia I have become an expert in quantum simulation and performed a recent benchmark quantum simulation experiment using a photonic approach. I am therefore in a unique position to help the group in Innsbruck achieve these goals and establish itself as a world leader in quantum simulation.'
Introduzione (Teaser)
EU-funded physicists have made considerable inroads with regard to investigating complex physical phenomena using a universal quantum simulator.
Descrizione progetto (Article)
Physical phenomena are often described by equations that are too complicated to solve and physicists use computer model simulations for this purpose. This methodology is not applicable to quantum systems due to the limited processing power of classical computers.
The number of parameters and equations that describe a quantum state and its dynamics grow exponentially with the number of particles involved. Scientists working on the 'Universal quantum simulation with trapped ions' (UQSI) project explored an alternative approach for quantum systems. Specifically, they built a highly controllable quantum system that can perform the simulations. This quantum simulator is based on a string of six calcium ions. The mathematical description of the phenomenon to be investigated is programmed using a series of laser pulses to perform the quantum calculations with ions.
The highly-cooled and electrically-trapped calcium atoms were used as carriers of quantum bits (qubits). The initial state of the system to be investigated was encoded in these qubits. Its dynamics were approximated with a sequence of 100 quantum gates. The full time evolution of networks of interacting particles, which are models of magnetism and exhibit rich dynamics, was simulated efficiently. An added bonus is the possibility of programming the USQI quantum simulator to simulate any physical system.
Researchers at the Austrian Academy of Sciences in Innsbruck are currently implementing the next generation of quantum simulations using up to 50 calcium ions with the USQI simulator. The research work conducted during the USQI project has been published online in the journal http://www.sciencemag.org/content/334/6052/57 (Science) and also presented in several international conferences.
