The important distinction is between a powerful algorithm and a machine capable of running it at the required scale. A laboratory milestone does not mean every encrypted connection has suddenly become readable. This video is a useful starting point for understanding both the potential and the engineering hurdles, without treating a quantum computer as a faster version of an ordinary laptop.
