# What is the decoherence time scale for the most promising quantum computing implementations

I'm searching for some data about decoherence time scales for qubits in modern quantum computing implementations.

The only reference I have is a table in "Quantum computation and quantum information" - Nielsen&Chuang , but it's an "old" book and with no references for the values.

(references are very appreciated)

edit: with data I mean time scales
