FieldLine
Boulder's FieldLine builds quantum magnetometers sensitive enough to image the brain without cryogenics.
FieldLine builds optically pumped magnetometers (OPMs), quantum sensors that detect magnetic fields by watching how atoms respond to light, and points them at the most interesting magnetic source around: the human brain. Its sensor arrays enable magnetoencephalography (MEG) without the liquid-helium-cooled SQUID arrays and magnetically shielded rooms that made traditional MEG a multi-million-dollar installation.
Wearable, cryogen-free brain imaging is the kind of application that makes 'quantum sensing' concrete: epilepsy surgical mapping, neuroscience research, pediatric imaging where rigid helmets fail. FieldLine's sensors have shipped to research clients, placing it among the Colorado quantum companies with actual products in actual customers' hands, a rarer club than the funding announcements suggest.
Why it matters to the Valley: quantum sensing reaches revenue years before quantum computing, and FieldLine is Boulder's cleanest example.
