Moore’s Law has prevailed since 1965, predicting that the integration density of chips will be doubled approximately every 18 months or so, which has resulted in nanoscale in- tegration associated with 7 nm technologies at the time of writing. At this scale however we are about to enter the transitory range between classical and quantum physics. Based on the brilliant proposition by Feynman a new breed of information bearers was born, where the quantum bits are mapped for example to the spin of an electron. As a benefit, the alluring properties of the nano-scale quantum world have opened up a whole spate of opportunities in signal processing and communications, as discussed in this easy-reading discourse requiring no background in quantum physics.
