Silicon Qubits Aren’t Winning Yet. Manufacturing Could Change That
The narrative often suggests an inevitable progression: silicon, the bedrock of the digital age, will seamlessly transition into the quantum...
Silicon Qubits Fail Because Their Atoms Sit Randomly
Researchers have traced the device-to-device swings in silicon spin-qubit valley splitting to random atomic-scale disorder inside the quantum well that...
Sound Could Carry Quantum Signals Across a Whole Chip – On Paper
Here’s a small, stubborn problem at the heart of building a big quantum computer. The qubits can usually only talk...
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...
