A new type of 'flexible' quantum computer can be reprogrammed with lasers

A fully reprogrammable quantum computer has been built and tested for the first time. The test marks a milestone in the development of powerful problem-solving machines that harness the strange properties of sub-atomic particles. At the heart of the device are just five ions - electrically charged atoms - trapped in a magnetic field, which are vibrated by precisely targeted laser beams.
