Scale at speed - quantum progress

The ability to go beyond the binary constraints of classical computing into a realm of qubits, which may simultaneously be in both one and zero states, opens the way to crunching data and pattern discovery - think transaction monitoring and connecting entities - at levels hitherto undreamt of. Advances are rapid but there's still practical, if not theoretical, ground to cover, Keith Nuthall finds.
