2.9 Summary

Classical computers have been around since the 1940s and are based on using bits, 1s and 0s, to store and manipulate information. This is naturally connected to logic, as we can think of 1 or 0 as True or False, respectively, and vice versa. From logic operators like and, we created logic circuits that perform higher-level operations such as addition. Circuits implement portions of algorithms.

Since all algorithms to accomplish a goal are not equal, we saw that having some idea of measuring the time and memory complexity of what we are doing is essential. By understanding the classical case, we’ll later be able to show where we can get a quantum improvement.
