The main difference between a quantum computer and a classical one is the qubit. Qubits are like classical bits, in that they hold binary values of either 1 or 0, on or off, true or false, etc. However, qubits, being quantum objects, can be in a superposition of both states at once. The physical manifestation … Continue reading Thoughts about quantum computing and the wave function
Read any mainstream neuroscience book, and one of the things you'll typically see is an admission that while a lot is known about the operations of neurons and synapses, and a lot about high level signalling patterns in various brain regions, along with a good amount on how sensory processing happens in some regions (such … Continue reading Assembly Calculus: the missing link between mind and brain?
Kevin Lande has an article up at Aeon which is one of the best discussions of the brain as a computational system that I've seen in a while. For an idea of the spirit of the piece: The claim that the brain is a computer is not merely a metaphor – but it is not … Continue reading The brain is a computer, but what is a computer?
Peter Kassan has an article at Skeptic Magazine which sets out to disprove the simulation hypothesis, the idea that we're all living in a computer simulation. I personally find arguing about the simulation hypothesis unproductive. Short of the simulation owner deciding to jump in and contact us, we can't prove the hypothesis. Even if the … Continue reading Does information require conscious interpretation to be information?
I found this video on quantum computing educational. It confirmed some things that I've been pondering about quantum computing for a while, notably its limitations, which are discussed after about the five minute mark. http://www.youtube.com/watch?v=g_IaVepNDT4 The strength of quantum computing is that it makes use of superpositions, the fact that quantum particles can be in multiple … Continue reading Quantum computing will not rescue Moore’s Law
