Quantum computing is the use of quantum-mechanical phenomena such as superposition and entanglement to perform a computation. The first quantum computers were built in the late 1990s, and commercial quantum computers came to market in 2011, when D-Wave announced a 128-qubit quantum computer. While D-Wave’s approach to quantum computing focuses on optimization challenges, the universal quantum computer, as built by Google, IBM, and Intel, which applied superconducting circuits, will address a broader range of problems. As we see greater amounts of data being created, the ability to analyse and use that data to deliver insights will be key, and quantum computing promises superior capabilities.
