Dipolar Coupling Errors in Nuclear Spin Qubits
Advanced Science, EarlyView.Multi‐nuclear spin registers of phosphorus‐atom qubits in silicon have demonstrated 99.99% single and >$>$99.9% two qubit gate fidelities. Despite nanometer separation, read‐out fidelities between individual nuclear spins within the register are not identical.

Using 13C-, 15N-, and 18O stable isotope analysis of human bone tissue to identify transhumance, high altitude habitation and reconstruct palaeodiet for the early medieval Alpine population at Volders, Austria [PDF]
, 2007 The analysis of stable isotopes of oxygen from structural carbonate in archaeological human bone samples originating from an early medieval cemetery in the Alpine community of Volders, Austria were used to determine the utilization of higher altitudes ...

Investigations of the Evolved Molecular Basis for Terpenoid Biosynthesis in Marine Sponges
Advanced Science, EarlyView.Confirming and extending a previous observation in another Bubarida sponge, genomic and functional analyses of A. cavernosa reveal that sponges retain the mevalonate pathway and employ single α‐domain T1TSs and UbiA‐type TSs for terpenoid biosynthesis. The absence of T1TSs clustering with other biosynthetic genes tentatively suggests, based on limited ...
