'If you drop a single phosphorous atom into a silicon crystal, it replaces a silicon atom. ', "Although I write a lot about quantum computing, I've not really paid much attention to performing quantum computations with silicon-based qubits."
'Then, if you control that overlap, you control how the two qubits couple. '
'The alternative, favored by Simmons, is to couple qubits through optical signals. '
'According to Simmons, the problem with coupling qubits in silicon is due to precision. '
