Quantum computers: End of Moore-law classic transistors
When the p-n-p atoms, that work as transistor in classic chips, get to the size of 5,3 or less atoms (between the emitter and collector), whose work is controlled classically by voltage gates to allow software programing to control either electrons in/out/amplified, are now affected by the quantum super positioning of spins (whatever thing is used: could be p-doped electron/polar photons /molecules polarity/condenses/ ion traps/ or just the nucleolus of the p-doped silicon atom itself (or carbon diamonds in the future?)) . Since they are now in entanglement and in quantum tunneling superposition, expect the nearest elections (that used to travel across to the collector end in a controlled way) to respond to those quantum spins thus behave much more unexpectedly and effectively, as if it was telling the electron to go and not go in the same time (0 and 1 simultaneously) making ‘n’ qbits equal to 2^n classic bits.
Why are those quantum spins weird causing ‘n’ qbits equal to 2^n bits? Because the up/down and down/up spin states are not stable neither determinant; however they are just opposite and unknown.
Programming them is a software challenge that utilizes logic of probabilities of binary bits for each state. Controlling/reading their input/output in a stable accurate way is another challenge as now they use MRI resonance instead of logic voltage gates, and expect Li-Fi technology to be tuned and incorporated with MRI to deliver possible richer codes in the future. Storing them coldly without disturbance is an engineering challenge where now they store them near-abs-zero separately. Subjects that we’ll talk about in another day.
