Editor's choice: quantum computing

Quantum computers have developed enormously in the past decade, moving beyond theoretical calculations to real-world applications. Systems which use comparatively low numbers of qubits have been accessible to researchers for some time and, despite the inherent limitations, the number of ingenious applications using this hardware has clearly demonstrated their power. Quantum computers will soon surpass the limits of classical computing reliably, meaning that the need for viable quantum computing-friendly algorithms and use-cases will continue to grow. Here, we present a selection of Scientific Reports papers in the area of quantum information and annealing.
