Quantum Computing – the four challenges

For all the spilled ink and breathless prose about quantum computing (QC), there remain four major challenges to overcome before it takes the place of classical silicon computing. • Coherence (the quantum state of data) • Entanglement (quantum teleportation) • Error Correction • Languages and compilers The PC on your desk, the smartphone in your pocket, and the biggest computers at the NSA manipulate bits that can be either on or off, one or zero, true or false.

Quantum computing promises to be a key development in the next decade.  It’s not magic and nor is it earth-shattering, despite the amount of spilled ink and breathless documentaries on the subject. The Trend Fifty years ago, Gordon Moore observed that the density of integrated circuits double every two years.  Since then, chip speeds and densities have improved to allow the cost of computing to drop by half every eighteen months.  We’re approaching the limit of the current chip making…
