## Progress in quantum computing using superconducting circuits

In the past several years, remarkable progress has been made in the quality and complexity of superconducting circuits. Coherence times improved by 1,000,000x from less than 1ns to more than 100 us, and it has become possible to do multi-qubit gates and small algorithms. I will present an overview of how quantum computing works and detail progress in the circuit based model of quantum computation using superconducting elements as qubits and gates. I will conclude with discussion of some of the current challenges faced by experimental quantum computing efforts.
