SUMMARY:Superconducting Quantum Computing \, Physics Department Colloq
 uium\, John Martinis\, University of California\, Santa Barbara
DESCRIPTION:Recent developments of surface codes now place superconduc
 ting quantum computing at an important crossroad\, where aEurooeproof 
 of conceptaEuro experiments involving small numbers of qubits can be t
 ransitioned to more challenging and systematic approaches that could a
 ctually lead to building a quantum computer.  Although the integrated 
 circuit nature of these qubits helps with the design of a complex arch
 itecture and control system\, it also presents a serious challenge for
  coherence since the quantum wavefunctions are in contact with a varie
 ty of materials defects.  I will review both logic gate design and rec
 ent developments in coherence in superconducting qubits\, and argue th
 at state-of-the-art devices are now near the fault tolerant threshold.
   Future progress looks promising for fidelity ten times better than t
 hreshold\, as needed for scalable quantum error correction and computa
 tion.
