Exploring small quantum error correcting codes with superconducting qubits

Presenting Author: Jay Gambetta, (IBM)

I will review IBM's current approach towards quantum computing with superconducting qubits. The goal is to build a system using quantum error correction schemes based on rotated surface codes, which has a high error threshold, requires only nearest-neighbor qubit interactions, and uses simple syndrome extraction circuits. I will discuss our results on achieving high fidelity two- and single- quit gates, long coherence times, and our recent results on demonstrating small codes on square lattices of superconducting qubits.
