A new phase of matter that could be protective against a range of errors in quantum computers has been demonstrated by researchers at the University of British Columbia (UBC)<\/a>, quantum computing company Quantinuum, and New York\u2019s Flatiron Institute<\/a>.<\/p>\n The research, that was published in Nature<\/em>, reveals a new topological phase utilising Quantinuum\u2019s trapped ion quantum simulator. This phase arises outside of equilibrium, the default for most systems \u2013 which cannot exist in equilibrium \u2013 offering a way to prevent qubits (the quantum equivalent of bits) from entangling.<\/p>\n \u201cOne problem in quantum computing is that if you have qubits that are coupled to each other, but you did not mean them to be, they can accidentally entangle themselves,\u201d explained Dr Andrew Potter, an Assistant Professor in UBC\u2019s Department of Physics and Astronomy, who joined the Stewart Blusson Quantum Matter Institute last year.<\/p>\n \u201cThat entanglement can cause errors, or crosstalk, between the qubits. These errors represent a significant barrier to achieving a functional quantum computing platform.\u201d<\/p>\nAmending errors in quantum computers<\/h3>\n
