What is it about Canadians and quantum computing?
A Canadian company called D:Wave has the best claim to be making and selling quantum computers. Now a research team at Canada's Simon Fraser University has announced that it has held a quantum memory state stable at room temperature for 39 minutes. This is 100 times longer than the previous record, and it has got the scientific community excited. In conventional computers, "bits" of data are stored as a string of 1s and 0s. In a quantum system, quantum bits, or "qubits" are stored in a so-called "superposition state" in which they can be both 1s and 0 at the...
