Quantum Computing and Simulation

Quantum computing is the art of harnessing quantum phenomena, such as superposition, interference, and entanglement, to solve hard mathematical problems. On a similar route, the purpose of quantum simulators is to reproduce the properties of relevant quantum systems that cannot be accessed experimentally, nor simulated on existing supercomputers. The physical implementation of quantum computing and simulation however represents a formidable scientific and technological challenge, which is currently involving academic and industrial institutions worldwide. In fact, a deep understanding of the hardware components is required in order to operate these quantum devices with the required accuracy, along with an extreme degree of experimental control on their physical properties and dynamics.

At CNR Nano we investigate some of the main platforms for the realization of quantum computers and simulators, based on the use of spins in semiconductor and molecular systems, superconducting qubits and electronics, hybrid semiconductor/superconductor systems for topological quantum computation, and programmable quantum simulators based on semiconductor frequency combs. We aim to use quantum annealing and simulation to predict properties of molecules and materials. Theoretical investigation and simulation of the best protocols in control and manipulation of quantum hardware is done in parallel to the experimental realizations, providing feedback on materials, design, and measurement setup.
