Solid-state qubits: Forget about being clean, embrace mess

New findings debunk previous wisdom that solid-state qubits need to be super dilute in an ultra-clean material to achieve long lifetimes. Instead, cram lots of rare-earth ions into a crystal, and some will form pairs that ...

Generating stable qubits at room temperature

A group of researchers reports that they have achieved quantum coherence at room temperature, which is the ability of a quantum system to maintain a well-defined state over time without getting affected by surrounding disturbances
