By <a href="http://jcartwright.co.uk/">Jon Cartwright</a> -<br><br>A quantum analogue of data compression has been demonstrated for the first time in the lab. Physicists working in Canada and Japan have squeezed quantum information contained in three quantum bits (qubits) into two qubits. The technique could pave the way for a more effective use of quantum memories and offers a new method of testing quantum logic devices.<br><br><a href="_">READ MORE ON PHYSICSWORLD.COM</a>
