### Blogs against decoherence

If you're interested in a blog whose main enemy is decoherence - because they want to construct a quantum computer - see
Everything new you need to know about the realization of quantum bits.

1. I am not sure why you would say they are the enemy of decoherence?

I tried to follow up on this to understand.

Can you go into more detail to help explain your statement ?

2. " Retaining quantum coherence is a central requirement in quantum information processing. Solid-state qubits, including superconducting ones, couple to environmental degrees of freedom that potentially lead to dephasing. This dephasing is commonly associated with low-frequency noise, though higher-frequency resonant modes are harmful as well. "
