- Quantum thermodynamics for quantum computing
- Magnetic fields take the lead in ultracold reactionsNature Physics, Published online: 27 January 2025; doi:10.1038/s41567-024-02756-x Ultracold recombination reactions typically produce molecules in many uncontrolled quantum states. Quantum control over reaction products has now been demonstrated via magnetic Feshbach resonances.
- Murmurations of electric dipolesNature Physics, Published online: 27 January 2025; doi:10.1038/s41567-024-02777-6 Stable and metastable electrical dipole patterns have been imaged and manipulated using in situ heating and cooling in ferroelectric superlattices.
- A many-body quantum register for a spin qubitNature Physics, Published online: 24 January 2025; doi:10.1038/s41567-024-02746-z The thousands of nuclear spins surrounding gallium arsenide quantum dots can interface with electron spin qubits and photons. With quantum engineering, this nuclear spin ensemble becomes a robust register for quantum information storage.
- Experimental fault-tolerant code switchingNature Physics, Published online: 24 January 2025; doi:10.1038/s41567-024-02727-2 Quantum error correction is essential for reliable quantum computing, but no single code supports all required fault-tolerant gates. The demonstration of switching between two codes now enables universal quantum computation with reduced overhead.
- Gauge theories on a quantum computerNature Physics, Published online: 23 January 2025; doi:10.1038/s41567-024-02758-9 Many important models in theoretical physics — including the standard model of particle physics — are governed by local ‘gauge’ symmetries. Now, a quantum computer has successfully simulated a lattice gauge theory by leveraging this rich symmetry structure.
- Time-hidden magnetic order in a multi-orbital Mott insulatorNature Physics, Published online: 23 January 2025; doi:10.1038/s41567-024-02752-1 Searches for metastable states with properties not found in thermal equilibrium have been restricted to either ultrafast or slow timescales. A metastable state in an intermediate time window has now been identified in a photo-doped Mott insulator.
- Tissue wrinkles foreshadow cancerNature Physics, Published online: 22 January 2025; doi:10.1038/s41567-024-02763-y In a cancer mouse model, wrinkling patterns in bladder-lining tissue differ from their healthy counterparts. Changes in tissue-mechanical properties that alter elastic buckling instabilities explain this observation.
