Attosecond charge migration in a neutral molecule has been observed to decohere within approximately 10 fs. However, this does not mean that the electronic coherence is irreversibly lost, as the charge migration is observed to revive after 40–50 fs. These findings have the potential to enable laser control of photochemical processes.

Trapped ion quantum computers can use two different kinds of ion to avoid crosstalk between adjacent qubits. Encoding two different qubit types in only one ion species can achieve the same goal while reducing experimental complexity.

Measurements of four different infinite-layer nickelates show that magnetic behaviour coexists with superconductivity. This is different from what is seen in cuprates, giving a strong distinction between the two classes of oxide superconductors.

Quantum computing with trapped ions requires qubits that can store and manipulate quantum information, and others that can be used for destructive incoherent operations. Different states of ytterbium-171 ions can be used to realize both qubit types

Interactive protocols can verify that a quantum computer exhibits a computational speedup using only classical analysis of its output. Exploiting a connection to Bell’s theorem gives a simpler protocol that is much less demanding for experiments.
