                  In balance: Quantum computing needs the right combination of order and disorder

                  Research conducted within the Cluster of Excellence ‘Matter and Light for Quantum Computing’ (ML4Q) has analysed cutting-edge device structures of quantum computers to demonstrate that some of them are indeed operating dangerously close to a threshold of chaotic meltdown. The challenge is to walk a thin line between too high, but also too low disorder to safeguard device operation. The study ‘Transmon platform for quantum computing challenged by chaotic fluctuations’ has been published today in Nature Communications.

                  Error-free quantum computer is coming closer

                  Quantum computers are expected to be the computers of the future. However, today's systems are still too error-prone for practical use. In two publications in the current issue of the renowned scientific journal Nature, a team around Prof. Markus Müller from Forschungszentrum Jülich and RWTH Aachen University has now presented two new solutions, which are intended to protect the results from errors.
