The Quantum Advantage Argument Just Changed Currency, From Speed to Watts
For a decade the quantum advantage debate has been an argument about time. Can the machine solve a problem faster...
Quantum Computing Runs on Helium-3, and Most of It Comes From Old Weapons Stockpiles
Here’s a supply chain nobody puts on a slide. Superconducting quantum computers have to be chilled to a hair above...
Stamping Exotic Materials Onto Silicon Chips Could Unlock Better Photonics
Silicon photonics has a materials problem, and researchers at Ghent University and imec think a printing technique can solve it....
A Ribbon Nine Atoms Wide That Snitches on Radiation
Here’s a design problem that sounds impossible. You need a sensor that sits in one of the most hostile places...
U.S. Labs Make Ultra-Pure Silicon and Germanium for Quantum Chips
Two U.S. national laboratories say they can now produce silicon and germanium feedstock pure enough to build quieter qubits, and...
IQM and Deutsche Bahn Test Quantum Scheduling on Real Rail Data
IQM and Deutsche Bahn have run a quantum optimization experiment on an actual railway schedule. The dataset covered 190 trips...
Scientists Made a New State of Matter Inside a Quantum Computer, Then Braided It
Here’s a sentence that shouldn’t be possible: a team of physicists took the qubits inside a quantum computer, coaxed them...
This Entangled State Shrugs Off the Fiber Noise Everyone Else Fights
Sending entanglement down an optical fiber is normally a nightmare of babysitting. Fiber gets warm, gets bent, gets nudged, and...
ESA Installs Its First Quantum Computer for Earth Observation
The European Space Agency (ESA) has installed its first quantum computer at ESRIN, its Earth-observation center near Rome. The machine,...
Arq Raises $1.4 Million to Build Quantum Repeaters for a Future Quantum Internet
Arq, a quantum networking startup founded in 2025, has raised a $1.4 million pre-seed round to develop the hardware needed...
