7.1. Quantum computing
The initial quantum circuit model of computation as a time-ordered sequence of logical quantum gates performing a unitary evolution of the state of a quantum register has evolved into a tightly integrated model of dynamic quantum circuits that allow concurrent classical processing of mid-circuit measurement results [Corcoles] [IBM_mid]. This new paradigm of dynamic quantum computation paves the way to a smooth transition from classical to quantum-boosted computing.
An often-overlooked potential quantum advantage is the energy efficiency of quantum computation [Auffeves] [Q Daily] [Quantum_AI] [Thibault]. The quantum supremacy experiment [Arute] involved an energy consumption three orders of magnitude smaller than the one a high-performance computer would require to achieve an exact computation of the expected result of the experiment. Determining the conditions under which an energetic quantum advantage could be achieved is an open research topic [Auffeves...
