On Q-putting...I really couldn't say how many QDots might be needed either, but this [big picture] article might provide a starting point in trying to put a number on it. Near as I can determine, from my laymens vantage point, it takes two QDots to make one entangled QuBit:
"An algorithm using, say, five entangled qubits can effectively do 25, or 32, computations at once, whereas a classical computer would have to do those 32 computations in succession. As few as 300 fully entangled qubits could, theoretically, sustain more parallel computations than there are atoms in the universe."
.....and related....
"Intel [the only commercial Stateside player exploring QD's in Q-putting] made one of the biggest bets, announcing in 2015 that it would invest $50 million into research at QuTech, an offshoot of Delft University of Technology in the Netherlands. The company is focusing on silicon quantum dots, often called "artificial atoms." A quantum dot qubit is a small chunk of material in which, as in an atom, the quantum states of an electron can represent 0 and 1. Unlike ions or atoms, however, a quantum dot doesn't need lasers to trap it.
Early quantum dots were made from near perfect crystals of gallium arsenide, but researchers have turned to silicon, hoping to leverage the massive manufacturing infrastructure of the semiconductor industry. "I think [Intel's] heart is with silicon," says Leo Kouwenhoven, scientific director of QuTech. "That's what they're good at." But silicon-based qubits are well behind those based on ions or superconductors, with the first two-qubit logic gate reported only last year by a group at the University of New South Wales in Sydney, Australia."
