Talk:Indeterminacy in concurrent computation
Article for deletion?
I dunno, this article just sounds plain old confused and wrong to me; I'm tempted to suggest deletion. Arguing that a hung gate is a form of quantum indeterminacy is certainly a novel idea, but I think a whole lotta work would need to be done to prove this, in particular, ruling out purely classical explanations like ground bounce and what not. I doubt that anyone who actually designs real transistors for a living would agree with such an assessment. I'd need to see something other than handwaving to believe this. linas 04:19, 16 September 2005 (UTC)
Disputed statement
I don't believe this:
- Arbiters are designed to resolve this instability as rapidly as possible into a stable state, a process known as quantum decoherence
For many reasons. Resolution into stability is not decoherence. Metastability might theoretically be a result of superposition of states, but I have seen no evidence for this in practice.

Can Quantum Synchronizers Solve the Metastability Problem of Asynchronous Digital Systems?, Vol. 1, No. 4 (1990) 329-342. Reinhard Männer
Abstract:
- The synchronization of asynchronous signals can lead to metastable behavior and malfunction of digital circuits. It is believed — but not proved — that metastability principally cannot be avoided. Confusion exists about its practical importance. This paper shows that metastable behavior can be avoided by usage of quantum synchronizers in principle, but not in practice, and that conventional synchronizers unavoidably show metastable behavior in principle, but not in practice, if properly designed
