Which would you rather have, breadth or depth? Suppose I give you the choice between the following two directions in experimental research in quantum computing in the next five years: either a few (say ten to thirty) qubits with extremely low decoherence and high control precision (perhaps even a high enough to perform quantum error correction) or a huge number of qubits (say hundreds to thousands to millions) with fairly poor decoherence and control. Assume that in both cases, fabrication can be done with a fairly high degree of sophistication. Of of these two options, which would you perfer to see in the near future? <\/p>\n","protected":false},"excerpt":{"rendered":"
