By coupling two fluxonium qubits through an inductive circuit rather than through a capacitor, researchers have realized a high-fidelity two-qubit gate.
Researchers record the longest Rydberg-atom lifetime by placing strontium atoms in “circular” states, where the outer electrons move in planet-like orbits.
The commercialization of magnesium-ion batteries could be closer thanks to the development of a cathode material inspired by multispecies metal alloys.
