Towards fault-tolerant quantum computing with trapped ions
Like their classical counterparts, quantum computers can, in theory, cope with imperfections?provided that these are small enough. The regime of fault-tolerant quantum computing has now been reached for a system based on trapped ions, in which a gate operation for entangling qubits has been implemented with a fidelity exceeding 99%.
