The answer lives at the intersection of quantum chemistry and quantum computing. Let’s go exploring. Chemistry, at its heart, is not about beakers and flames. It is about electrons . Where they are, where they go, and how they dance with one another.
But electrons do not obey the rules of our everyday world. They obey quantum rules. A classical electron is like a marble on a table. You can point to it: “There.” The answer lives at the intersection of quantum
To simulate one entangled electron on a classical machine, you need to track an enormous list of probabilities. For 300 entangled electrons? You would need more bits than there are atoms in the observable universe. It is about electrons
But electrons do not think in bits. They think in superpositions —0 and 1 at the same time, with a certain probability for each. They obey quantum rules
Why does a molecule smell? How could a computer solve a problem in seconds that would take a classical machine billions of years? And what do these two questions have in common?
