About The Conference
Superconducting Qubits and Algorithms (SQA) is a not-for-profit scientific conference with a focus on science, technology, and algorithms relevant for superconducting quantum computers. It is organized by QuTech, Orange Quantum Systems, and IQM Quantum Computers in cooperation with the scientific community. Our goal is to make this the leading event in its field.
