Keeper L. Sharkey Quantum Chemistry And Computing For The Curious Best May 2026

And for the curious? That is the best place to be: at the frontier where we don’t yet have all the answers, but we finally have the right machine to ask the questions. Keep looking up. Keep asking why. The quantum world is not spooky—it is just patiently waiting for us to learn its language.

As physicist Richard Feynman famously said in 1982: “Nature isn’t classical, dammit. So if you want to simulate nature, you’d better make it quantum mechanical.” And for the curious

But electrons do not think in bits. They think in superpositions —0 and 1 at the same time, with a certain probability for each. Keep asking why

By Keeper L. Sharkey (spirit of the curious) So if you want to simulate nature, you’d

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?

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.

Here is what that unlocks: Instead of approximating (as classical methods like DFT do), a quantum computer could solve the Schrödinger equation directly for small-to-medium molecules. You could watch a bond break and form in real quantum time. 2. Catalyst Design The Haber-Bosch process (which makes fertilizer for half the world’s food) uses an iron catalyst. We don’t fully understand why it works. A quantum simulation could reveal the mechanism, allowing us to design catalysts that work at room temperature and pressure—saving massive energy. 3. Battery Materials Simulating electron flow in novel lithium-sulfur or solid-state electrolytes. A quantum computer could search through millions of candidate materials in the time it takes a classical supercomputer to test one. 4. Nitrogen Fixation & Carbon Capture Enzymes like nitrogenase fix nitrogen at ambient conditions—something industry cannot replicate. Understanding their quantum electron dynamics could unlock green chemistry for fuel production and carbon recycling. Part 5: But We Are Not There Yet (The Honest Truth) Let’s be curious but clear-eyed.
