1/f noise: implications for solid-state quantum information

Understand

The efficiency of the future devices for quantum information processing will be limited mostly by the finite decoherence rates of the individual qubits and quantum gates.

• Recently, substantial progress was achieved in enhancing the time within which a solid-state qubit demonstrates coherent dynamics.
• This progress is based mostly on a successful isolation of the qubits from external decoherence sources obtained by clever engineering.
• Under these conditions, the material-inherent sources of noise start to play a crucial role.
