Although quantum computers have huge potential to solve new kinds of problems, the technology is currently prone to error. An alteration in their surrounding environment, such as a change in temperature, pressure, or magnetic field, can disrupt their fragile computation building blocks, called qubits<\/a>.<\/p>\n Now, researchers at the University of Chicago\u2019s Pritzker School of Molecular Engineering (PME) have found a new approach to constantly monitor the noise around a quantum system. The new method allows the qubits to be adjusted in real-time to minimise error.<\/p>\n The approach relies on spectator qubits. These are a set of qubits embedded in the computer with the role of measuring outside noise rather than storing data.<\/p>\n The information gathered by spectator qubits is then used to cancel out noise in vita-data processing qubits.<\/p>\n Research leader Assistant Professor Hannes Bernien compared the new system to noise-cancelling headphones which monitor surrounding noises and emit opposing frequencies to cancel them out.<\/p>\n Bernien said: \u201cWith this approach, we can very robustly improve the quality of the data qubits. \u201cI see this as being very important in the context of quantum computing and quantum simulation.\u201d<\/p>\n
