Spin glass physics with trapped ions

number-partitioning, which refers to the easy undertaking of dividing a fixed of numbers into  companies of same sums is, in truth, a totally tough problem to resolve with classical computers.

regularly, such issues can be related to a physical version, which then allows for solving the problem by using locating the minimal electricity kingdom of the model. right here, an essential function is played via spin glass models, this is, models describing a group of tiny magnets interacting with every different in a random style.

in the current paintings published in Nature Communications, Dr. Tobias Grass, David Raventós, Dr. Christian Gogolin, led via ICREA Prof. at ICFO Dr. Maciej Lewenstein, in collaboration with Dr. Bruno Julià-Díaz from the college of Barcelona (UB), lay the theoretical foundations for a quantum simulation of spin glass physics with trapped ions.

The concept proposed by using the crew of researchers indicates the way to tackle the problem of quantity partitioning via applying a strategy called "quantum annealing." this is done with the aid of to start with applying a sturdy magnetic discipline that's then switched off slowly during the simulation. on this way, the quantum kingdom is deformed till it fits with the preferred answer. this could be quicker than other methods to remedy the trouble.

The implementation of this approach is feasible with state-of-the-art strategies for trapping, cooling, and manipulating ions. As Dr. Grass in reality states, "in the past, we've got visible quantum simulations which remedy a trouble from quantum physics. In our approach, the same techniques are used to resolve a hassle from pc technology. The consequences of our have a look at opens a new route and brings us a step closer to the development of a quantum pc."
