After two decades of intensive experimental and theoretical research in quantum science, we have now reached a new era of quantum technologies. Several scenarios have been identified for which quantum information processing outperforms its classical analogue. Moreover, various implementations have demonstrated reliable control and operation of around ten qubits. Despite these efforts and advances, we are still very far away from a full-fledged quantum device mastering several thousand qubits.
