Quantum computer core. Light rays passing through the nanoscale crystal core of a quantum computer. Quantum computers, which are under development, are based on quantum mechanics and the principle of representing information in quantum bits (qubits) using quantum properties. This could involve optical properties of chemically doped crystals, like the one shown here. Quantum computing has the potential to massively increase computing power.

Physics

An ambitious look at quantum physics is fun – but overdoes it a little

Attempts to describe quantum physics are rarely enjoyable, but Paul Davies' zeal in Quantum 2.0 sometimes steers too close to hype, finds Karmela Padavic-Callaghan
