  • Random access memory has multiple data registers and uses addresses to specify which register should be read or modified. Now a quantum random access memory has been demonstrated that uses quantum addresses to return data in superposition.

  • Smyth et al. demonstrate that a cellular inhibitor of apoptosis, cIAP2, exacerbates inflammation and cardiac injury after myocardial infarction and that its inhibition, either genetically or via Smac mimetics, offers a promising immunotherapeutic strategy to reduce post-MI damage and progression to heart failure.

  • Nontrivial topologies are long believed to survive only in gapped systems, yet recent progress suggests their existence even at quantum critical points. By preparing low-lying states on a superconducting processor up to 100 qubits and applying entanglement Hamiltonian tomography, the authors experimentally observe these nontrivial topological properties and suggest low-lying states as useful quantum resources.

  • Quantum low-density parity-check error correction codes are anticipated to deliver high performance, but require long-range qubit–qubit interactions. Two of these error correction codes have now been successfully implemented on a superconducting device.

  • Quantum error mitigation refers to techniques that reduce, rather than correct, errors in quantum computing. Here the authors demonstrate zero-noise extrapolation applied to quantum error correction circuits on superconducting processors, effectively reducing logical errors and advancing early fault-tolerant quantum computing.

  • Stable and robust topological edge modes are observed at finite temperatures in an array of 100 programmable superconducting qubits because of emergent symmetries present in the prethermal regime of this system.

  • Many-body localization—a phenomenon where an isolated system fails to reach thermal equilibrium—has been studied with a programmable quantum processor, which reveals the crucial role played by the initial energy on the onset of localization.

  • Recently, there have been proposals to extend the concept of time crystals to topological order. Here the authors observe a prethermal topologically ordered time crystal on a superconducting quantum processor, where discrete time-translation symmetry breaking manifests for nonlocal rather than local observables.

  • The Greenberger-Horne-Zeilinger states are multipartite entangled quantum states with strong non-local entanglement. Here the authors generate large-scale states of this type with up to 60 qubits and show that discrete time crystals can effectively protect such fragile states.

  • Many-body quantum systems that escape thermalization are promising candidates for quantum information applications. A weak-ergodicity-breaking mechanism—quantum scarring—has now been observed with superconducting qubits in unconstrained models.

  • Zhang et al. show increased blood concentration of IGFBP7 in patients and a mouse model with heart failure (HF). IGFBP7 promotes cardiac senescence by stimulating IGF-1R/IRS/AKT-dependent suppression of FOXO3a, and Igfbp7 deficiency or inhibition attenuates cardiac dysfunction in a pressure overload mouse HF model, suggesting that therapeutic targeting of IGFBP7 might be promising for the treatment of HF.

  • Signatures of non-equilibrium Floquet SPT phases with a programmable superconducting quantum processor are observed in which the discrete time translational symmetry only breaks at the boundaries and not in the bulk.
