Instant Expert guide to quantum information

• Potential of Quantum Data – The promise
  Processing data in quantum states offers the prospect of peerlessly powerful, economical and secure number crunching. The challenge is to make it a reality
• Hardware – Building a quantum computer
  There are many ways of making “qubits” for a quantum computer to crunch, but any qubit worth using must tick a lot of boxes – and therein lies the rub
• Software – Killer apps
  What might we use quantum computers for? There are many suggestions – from super-encryption and heavyweight number-crunching to detecting gravity waves
• Prospects – Are we nearly there yet?
  Some living systems employ quantum information processing. If we can learn their secrets, personal quantum computers will no longer seem so fanciful an idea
