Title: Viable qubits in noisy environments
Abstract: Quantum sensors and qubits are usually two-level systems, quantum analogs of classical bits assuming binary values ‘0′ or ‘1′. They are useful to the extent to which superpositions of ‘0’ and ‘1’ persist despite a noisy environment. The standard prescription to avoid decoherence of solid-state qubits is their isolation via extreme dilution in ultrapure materials. We demonstrate a different strategy using a rare-earth insulator which realizes a dense random network of interacting two-level systems. Qubits with ultralong decoherence times emerge within this network because of rather than in spite of the interactions.
