The path to scalable quantum computing with silicon spin qubits

Silicon spin qubits have demonstrated some promising properties at the individual level, but the technology is beleaguered by a late start and high barriers to entry. To overcome these challenges, the quantum computing and electrical engineering communities will need to find novel ways to work together.
