Quantum computers get automatic error correction for the first time
Quantum computing chips could use heat to eliminate errorsChalmers University of Technology, Lovisa Håkansson
A tiny cooling device can automatically reset malfunctioning components of a quantum computer. Its performance suggests that manipulating heat could also enable other autonomous quantum devices.
Quantum computers aren’t yet fully practical because they make too many errors. In fact, if qubits – key components of this type of computer – accidentally heat up and become too energetic, they can end up in an erroneous state before the calculation even begins. One way to “reset” the qubits to their correct states is to cool them down.
Simone Gasparinetti at Chalmers University of Technology in Sweden and his colleagues have delegated this task to an autonomous q...
