Add to Calendar 2/13/2019 1:00 pm 2/13/2019 America/Chicago QI/AMO Seminar: "Superconducting Circuits for Quantum Information Processors and Quantum Networks" DESCRIPTION:

The performance of superconducting qubits has improved significantly over the past decade to the point where initial implementations of quantum error correction are already being pursued and processor sizes are approaching 50 qubits. Further advances in qubit performance require approaches to deal with the various mechanisms that lead to dephasing or relaxation in qubit circuits or microwave resonators. Alternatively, topologically protected qubit designs can provide a pathway to high-fidelity gate operations even in the presence of dissipation and noise. In order to build to yet larger processor sizes, new techniques are needed to address the overhead requirements for room-temperature electronics hardware and cryostat wiring for controlling and reading out large numbers of qubits. One approach to this challenge involves integrating superconducting classical digital circuitry with superconducting qubits for coherent control and readout. Finally, constructing quantum networks between superconducting qubit processor nodes coupled by optical photons requires a quantum microwave-to-optical transducer. One potential scheme for this transduction involves superconducting metamaterials coupled to nanomechanical resonators.
