The race towards demonstrating quantum supremacy and commercializing quantum computers has been the focus for most companies in the space of quantum computing. However, researchers found a piece of compelling evidence that errors found over the superconducting quantum computing chip are correlated.
The bits found on a classical computer either be a 1 or a 0 but cannot be both. On the other hand, the qubits on a quantum computer can be a 1 or a 0, or some linear combination of both states. This can lead to two types of error: bit flips or phase flips when there is a change in superposition states.
A research group from the University of Wisconsin-Madison is now working towards a mitigation strategy on building the fault-tolerant quantum computer.
