[math-fun] Bosons v Fermions in Quantum Computation ?
Is it just me, or does anyone else think that *bosons* are a better choice for Quantum Computation than *fermions* ? With bosons, a QC engineer has the option of putting a large number of bosons (i.e., a large amount of energy) into every state, while with Fermions, you're dealing with a single, quite small amount of energy state. Not a lot of design space to work with. We've also got lots and lots of experience with electrical and magnetic fields and electromagnetic photons. Yes, photons are "large" compared with the feature sizes enabled by electrons, but on the other hand, we're now approaching the ~ 1 nmeter size needed for quantum dots for visible light photons. What am I missing here?
http://nyu.timbyrnes.net/research/quantum-information-using-bose-einstein-co... There's a third option in two dimensions, the anyon. One promising model of quantum computation involves braided anyons, since relatively large perturbations won't change the braiding. https://en.wikipedia.org/wiki/Anyon#Non-abelian_anyons On Tue, Nov 27, 2018 at 8:42 PM Henry Baker <hbaker1@pipeline.com> wrote:
