The Quantum Zodiac
Every quantum computer is built from one kind of qubit, and the choice is never neutral. Each modality demands a different culture, rewards a different founder, fails in a different way. So we played a game. Forget which companies fund quantum. We sorted the entire Nasdaq-100 roster by the qubit each company would be if it were made of physics. The modality is a personality test.
It is a game. It is not random. Two of the names on this index whose real qubit we can check read like the physics they build.
Take that as a wink, not a result. It is two companies, we did the scoring ourselves, and a careful reader could score it differently. It also only covers the Nasdaq-100. The interesting part of quantum lives elsewhere: IBM on superconducting, IonQ and Quantinuum on ions, Rigetti on superconducting, D-Wave on annealing, PsiQuantum and Xanadu on photonics, Atom Computing and Pasqal on neutral atoms. Most are private or listed off this index, so they never enter the game below. This sort is about temperament, not a leaderboard of who is ahead.
The off-index names are the private or elsewhere-listed leaders that never enter this Nasdaq-100 game. Everything in the roster below is temperament, not a program.

How the sort worksMethodology
We inverted the obvious question. The naive sort asks which qubit does a company fund, which classifies only the four names with real programs and leaves ninety-plus blank. The intelligent sort asks which qubit a company already is, in its bones.
A modality is not just a physical approach. It is a solution to one problem, build a useful quantum computer, under a different constraint set, and the constraints force a culture. Superconducting's cryogenic burden forces a fab. Trapped ion's slow gates force patience. The physics and the org chart are one decision seen from two sides.
The six indicators
Resolving six scores into one house
The six-vector is not summed. Each house is a signature pattern, a set of axis scores that pull together, and a company joins the house its vector matches most sharply.
| House | Signature | Reads as |
|---|---|---|
| Firstborn | count first, capital heavy | scale first, infrastructure moat |
| Perfectionist | fidelity first, single focus | fewer, near flawless, tightly held |
| Fast Scaler | reconfigurable, count first, proof later | reshape one platform, grow explosively |
| Contrarian | long and contrarian, asset light network | networking native long bet |
| Disciplined Mfr. | process first, fidelity side | industrialize and pull ahead |
| Wildcard | binary variance, capital heavy | exotic asymmetric wager |
The tie-break, and the honesty layer
When a vector fits two signatures, the house is set by the single most load-bearing advantage, the one axis that, if removed, breaks the business. Then in order: a verified quantum program wins its house outright; absent that, the deepest moat wins; still tied, the rarer trait wins.
Over the scoring sits a hard factual flag. Builds it means a verified quantum program in that exact modality. Vibe means the temperament fits but the company builds no qubit. The tag never sets the house on its own. It only breaks ties and lets the convergence test run.
This is a game, not a model. Every company is hand-scored on the six axes from its public structure, so two careful analysts could differ by a point on a soft axis. The convergence test rests on n = 2. The vibe calls are interpretation, not measurement. Nothing here is a rating or investment advice.
