A new technique that efficiently retrieves scattered light from fluorescent sources can be used to record neuronal signals coming from deep within the brain. The technique, developed by physicists at ...

The phenomenal success of our integrated circuits managed to obscure an awkward fact: they’re not always the best way to solve problems. The features of modern computers—binary operations, separated ...

The basic mathematics of quantum mechanics will be reviewed for application to quantum computation. Classical physical computation (not with digital circuits) will be discussed, in particular ...
