# Coherence in my blog: A Quantum worldline

June 13, 2006 in

Remember the blog entries Quantum computer solves problem... and How to find some bombs... ? Well, they are related, since 'counterfactual computing' is related to 'interaction-free measurement'.

The last physics entry then referred to a paper Quantum to Classical Transition... that tries to explain interaction-free measurement based on a RBW point of view.

This new paper, The limits of counterfactual computation then relates again to the first link presented.

It's all a web of relations...
