| Description |
The central challenge in building a scalable quantum computer is achieving effective quantum error correction (QEC). Large arrays of superconducting qubits are currently a leading platform for the implementation of QEC. The success of these implementations relies on the synergy of accurate understanding of the device physics and associated noise, of efficient and practical quantum codes, and of the integration of these two in the form of tileable architectures.
In this conference, we plan to bring together scientists working in the following three major areas:
and encourage stronger communication between them. We especially hope to foster improved interactions between industry and academia.
