The computer made of atoms has a harder problem: staying useful
QuEra can arrange atoms with light and rent you time on a 256-qubit machine. Its next wager is less theatrical and more difficult: correcting mistakes fast enough that a quantum computer can earn its place beside a supercomputer.
The Quantum Computer That Wants a Seat Beside the GPU
AI keeps asking for more power. Sygaldry's wager is that the next useful server will have more than one kind of qubit - and a place beside the GPUs already humming in the data center.
The Computer That Replaces Its Own Atoms
Atom Computing thinks the route to a useful quantum machine begins with a strange convenience: when an atom misbehaves, nature has made billions of identical replacements.
Quantinuum’s $1.68 Billion Bet: Make Quantum Computing Boring Enough to Buy
Quantinuum has 98 trapped ions, an enterprise software stack and fresh public-market money. Its harder experiment is proving that exceptional fidelity can become an ordinary purchase order.
Qunnect
Qunnect is a New York-based deep-tech company building hardware that turns ordinary telecom fiber into scalable quantum networks. Its room-temperature, field-deployable devices distribute entangled photons over existing infrastructure - no cryogenics or vacuum chambers required. The flagship Carina product suite powers real-world quantum testbeds in New York and Berlin, and is sold to customers across finance, energy, telecom, and defense.
