报告摘要：
Quantum superconducting circuits are nanostructured superconducting
electrical networks with Josephson junctions. At low temperatures, their
quantum dynamics is described by using a few degrees of freedom with a
collective character. The parameters in the Hamiltonian depend on the
dimensions and topology of the circuit; superconducting quantum circuits
therefore behave as artificial atoms. Superconducting quantum circuits
have potential applications in quantum information processing and
provide a testbed for the study of light-matter interaction in a new
regime of ultra-strong interactions. The main focus of our research is
quantum computing with flux-type superconducting quantum bits. I will
discuss a new type of quantum gates applicable to two flux qubits which
requires a minimum amount of resources. I will also describe
experimental work in progress on the application of this method to a
system formed of a few qubits and also the possible application of this
scheme to electron spins in quantum dots.
