Applications of Quantum Computing with Superconducting Qubits — •Stefan Filipp — IBM Research - Zurich

In the recent years we have observed a rapid development of quantum technologies for the realization of quantum computers that promise to outperform conventional computers in certain types of problems. These include problems in optimization and machine learning, but also in the computation of complex many-body physical systems such as molecules or condensed matter. Assisted by conventional computing systems, hybrid quantum-classical architectures may soon allow us to solve some of today's computational challenges. Because of their relatively long coherence times and scalable fabrication methods superconducting quantum circuits are a promising candidate to realize such a quantum computing platform. We employ a variational algorithm that is based on a classical optimizer to guide the preparation of the quantum state on the quantum processor which encodes the solution to a given problem. This method is suited best for near-term applications on non-error corrected quantum hardware because it relies only on a small number of quantum operations and finishes within the coherence time of the system. First results in the field of quantum chemistry for computing the energy spectra of small molecules and in machine learning for classification protocols demonstrate the potential of this technology.
