NYC Quantum Computing Meetup June 8, 2021

Nick Bronn and Zlatko Minev from IBM (previous NYC QC Meetup speakers) will talk about Superconducting Quantum Circuit Design with Qiskit Metal.

Abstract:

Superconducting qubits have become a leading platform for building quantum processors in both academia and industry. As the field progress towards larger and more complex chip designs, we see a growing need to streamline the design flow process. To this end we have developed Qiskit Metal, a software tool designed to make the design, simulation, and analysis of quantum circuit layouts a faster and easier process. In this talk, we will, after briefly reviewing the physics and engineering of superconducting qubits, walk through the design flow of a superconducting qubit chip, using an example two qubit chip with in Qiskit Metal. First, we will generate our desired circuit components or select those already available in the Metal library. We will then begin to tune our structures to hit the desired quantum parameters, such as the qubit’s anharmonicity or the readout chi. We will accomplish this by rendering target components into the appropriate simulation, eg. Ansys Q3D, followed by the quantum analysis, eg. Lumped Oscillator Model (LOM). Once we have hit our target parameters, we then generate a GDS file of our qubit chip so that it is ready for fabrication.
