Quantum physics has already changed our lives. Thanks to the invention of the laser and the transistor — both products of quantum theory — almost every electronic device we use today is an example of quantum physics in action. We may now be on the brink of a second quantum revolution as we attempt to harness even more of the power of the quantum world. Quantum computing and quantum communication could impact many sectors, including healthcare, energy, finance, security, and entertainment. Recent studies predict a multibillion-dollar quantum industry by 2030. However, significant practical challenges need to be overcome before this level of large-scale impact is achievable.
