Quantum algorithms are touted as a way around some classically intractable problems such as the simulation of quantum mechanics. At the end of all quantum algorithms is a quantum measurement whereby classical data is extracted and utilized. In fact. many of the modern hybrid-classical approaches are essentially quantum measurements of states with short quantum circuit descriptions. https://www.roneverhart.com/Tokidoki-X-Hello-Kitty-and-Friends-1-Blind-Box/
