Step towards quantum computing
It's quantum discord - similar to background interference - not quantum entanglement, that may be the key to unlockin quantum computing, the study suggests. Image: alengo/iStockphoto Scientists have taken a quantum leap forward towards future computing after discovering that ‘background interference' in quantum-level measurements, may be the very thing they need to unlock the potential of quantum computing.In a paper published in Nature Physics, researchers from The University of Queensland, The Australian National University and The National University of Singapore (NUS), suggest that this interference – quantum discord – may be what will make a future quantum computer tick.“Up until a few years ago, researchers thought that realising quantum technologies would mean harnessing the most difficult-to-tame properties of the quantum world – the phenomenon known as ‘entanglement'.“But in the past few years, scientists have discovered examples of technologies that seem to work without entanglement, which has left us with the puzzle of...
