Quantum computing: Solid-state spins survive.

The article discusses several experiments aimed to improving the fidelity of quantum control in solid-state spin quantum bits and extending their coherent lifetimes. These experiments which focused on two distinct physical implementations of qubits, have demonstrated that manipulating spins with high-speed control pulses, in a technique known as dynamical decoupling, allows for high-fidelity control and improvement in the lifetimes of integrated quantum devices.
