The new quantum thermometer on a chip, in the foreground. It is probably the world’s fastest and most sensitive thermometer for measuring temperature at the…
DOE’s Lawrence Berkeley National Laboratory is using a sophisticated cooling system to keep qubits – the heart of quantum computers – cold enough for scientists…
Electron holes could be the solution to operational speed/coherence trade-off. A new study indicates holes the solution to operational speed/coherence trade-off, potential scaling up of…
Rotation of electron spins in superconductors of atomic-scale thickness may be used to make qubits for quantum computing. Superconductivity is known to be easily destroyed…
Lack of symmetry in qubits can’t fix errors in quantum computing, but might explain matter/antimatter imbalance. Unexpected twist in the Kibble-Zurek theory offers a new…
