Quantum computers could be the next big thing to hit the technology world, with scientists all around the world trying to figure out how to put theory into commercially-viable practice. This latest realisation could be the next step towards bringing a super-fast computer, tablet or even phone into the living room.
A letter published in Nature by a collection of scientists highlights what could be the perfect compound for making quantum computers: copper phthalocyanine, or in other words, the blue pigment common to many bank notes, including the £5 note. The electrons in this compound can achieve the ‘superposition’ state (where it’s technically in two states at the same time – think Schrodinger’s cat) needed to run a quantum computer, but the compound itself is far more readily and cheaply available than other options previously discussed.
