Photonic Quantum Computer

So I'm interested to know what you actually did for your thesis in writing your PhD. So I looked at it in semiconductor, right? We have electrons and holes, so a valence band, conduction band, right? But when you bring these electrons and holes to dimensions close to the bore radius, right? It's one wavelength of electron or the particle, right? So then you start seeing this like potential well problem inQuantum mechanics. Metil: "The holy grails for me is electronics and photonic quantum computer"
