DOI: 10.1103/physrevlett.121.250502
Abstract: Coherent errors are a dominant noise process in many quantum computing architectures. Unlike stochastic errors, these errors can combine constructively and grow into highly detrimental overrotations. To combat this, we introduce a simple technique for… read more here.
