THEY’RE BUILDING QUANTUM COMPUTERS OUT OF LIGHT…AND ALREADY MAKING MILLIONS
Most quantum computers need freezing temperatures and setups that look like alien life support systems.
A new startup, PsiQuantum, decided to skip all that trouble…
They’re using light—actual photons—to build quantum chips.
Photons don’t overheat. They don’t get noisy.
And they already fly through fiber-optic cables, like the ones powering the internet.
Problem is, they’re slippery.
Photons move fast, get lost, and are hard to control.
That’s why most scientists gave up on photonic quantum computers.
PsiQuantum didn’t.
They teamed up with GlobalFoundries, a major chip manufacturer, and now say they’re cranking out millions of these photon-powered chips—using the same machines that make phone processors.
Their latest chip hits 0.02% error for single qubit operations, and 0.8% for two-qubit fusion, which is shockingly good for a system made of literal light particles.
Instead of wiring up thousands of delicate qubits by hand, PsiQuantum’s building entire systems on silicon wafers—ready to scale to millions of qubits.
If it works, they’ve just made quantum hardware that’s faster, cooler, and easier to mass-produce than anything else on the market.

QUANTUM SCIENTISTS SPEED UP THE IMPOSSIBLE — WITHOUT BREAKING IT
Quantum computers are insanely fast, but measuring their data is painfully slow—and risky.
One wrong move, and the entire system collapses.
Now, researchers from the University of Bristol (with help from Oxford, x.com/MarioNawfal/st…
