Nature Physics, Published online: 06 May 2024; doi:10.1038/s41567-024-02442-yRotational symmetry is shown to protect the quadratic dispersion of out-of-plane flexural vibrations in graphene and other two-dimensional materials against phonon–phonon interactions, making the bending rigidity of these materials non-divergent. The quadratic dispersion is...

Nature Physics, Published online: 06 May 2024; doi:10.1038/s41567-024-02497-xThe hybrid architecture of Andreev spin qubits made using semiconductor–superconductor nanowires means that supercurrents can be used to inductively couple qubits over long distances.

Nature Physics, Published online: 06 May 2024; doi:10.1038/s41567-024-02481-5A successful silicon spin qubit design should be rapidly scalable by benefiting from industrial transistor technology. This investigation of exchange interactions between two FinFET qubits provides a guide to implementing two-qubit gates for hole spins.

Nature Physics, Published online: 03 May 2024; doi:10.1038/s41567-024-02463-7The Q-value of electron capture in 163Ho has been determined with an uncertainty of 0.6 eV c–2 through a combination of high-precision Penning-trap mass spectrometry and precise atomic physics calculations. This high-precision measurement provides insight into systematic errors...

Nature Physics, Published online: 01 May 2024; doi:10.1038/s41567-024-02482-4As counterparts to optical frequency combs, magnonic frequency combs could have broad applications if their initiation thresholds were low and the ‘teeth’ of the comb plentiful. Progress has now been made through exploiting so-called exceptional points to enhance the nonlinear...

Nature Physics, Published online: 01 May 2024; doi:10.1038/s41567-024-02480-6A practical and hardware-efficient blueprint for fault-tolerant quantum computing has been developed, using quantum low-density-parity-check codes and reconfigurable neutral-atom arrays. The scheme requires ten times fewer qubits and paves the way towards large-scale quantum...
