Engineers from UNSW’s Centre for Quantum Computation & Communication Technology (CQC2T) have created a new quantum bit which remains in a stable superposition for 10 times longer than previously achieved, dramatically expanding the time during which calculations could be performed in a future silicon quantum computer. UNSW is focused on developing quantum computers - theoretical processors based on quantum mechanics, with the potential to solve problems far beyond the scope of today’s supercomputers - in silicon, the material that has underpinned the information technology industry for decades. The feat, outlined this morning in the journal Nature Nanotechnology, is the latest record achieved by the UNSW centre and partner research groups.
Quantum teleportation brings to mind Star Trek‘s transporter, where crew members are disassembled in one location to be reassembled in another. Real quantum teleportation is a much more subtle effect where information is transferred between entangled quantum states. It’s a quantum trick that could give us the ultimate in secure communication. While quantum teleportation experiments have been performed countless times in the lab, doing it in the real world has proved a bit more challenging. But a recent experiment using a dark fibre portion of the internet has brought quantum teleportation one step closer to real world applications. The backbone of the internet is a network of optical fibre. Everything
