A recent paper published in Nature Physics (10th August 2020) has highlighted progress in dealing with noise in quantum systems. Noise represents one of the biggest barriers to effective and practical quantum computing as the qubit count increases. The team from Sydney show a new protocol for dealing with a 14-qubit super conducting system. The work allows a correlation matrix to be constructed highlighting interactions between qubits that has not previously been detected.
