Today’s post, Decoherent Essences was originally published on 30 April 2008. A summary (taken from the LW wiki):
Decoherence is implicit within physics, not an extra law on top of it. You can choose representations that make decoherence harder to see, just like you can choose representations that make apples harder to see, but exactly the same physical process still goes on; the apple doesn’t disappear and neither does decoherence. If you could make decoherence magically go away by choosing the right representation, we wouldn’t need to shield quantum computers from the environment.

This post is part of the Rerunning the Sequences series, where we’ll be going through Eliezer Yudkowsky’s old posts in order so that people who are interested can (re-)read and discuss them. The previous post was Decoherence is Pointless, and you can use the sequence_reruns tag or rss feed to follow the rest of the series.
Sequence reruns are a community-driven effort. You can participate by re-reading the sequence post, discussing it here, posting the next day’s sequence reruns post, or summarizing forthcoming articles on the wiki.
