MARKET MOVERS

Who's moving in quantum right now

The public quantum names ranked by price move — switch between today, the week and the month, and between gainers and losers.

All quantum stocks →
Data for research purposes only. Not investment advice. Prices delayed.

Moves are measured against the last close at or before the start of each window, so a listing with no session that far back is left out rather than shown as flat.

THE QUANT SCORE

One number. Four signals. Zero hype.

Every company gets a 0–100 Quant Score, normalized within its technology track — so a photonics seed startup is judged against its peers, not against a public giant.

Funding momentum40%

Capital raised, recency and round size versus track peers.

Patents25%

Filing velocity over 12 months, weighted for consistency.

Talent20%

Headcount growth and hiring pace as a leading indicator.

Research15%

Papers and citations — the science behind the roadmap.
