Smells like teen physics

The number 15 is created by quantum imaging, self-assembly of green-fluorescent-protein-active Escherichia coli bacteria, self-assembly of polystyrene beads and with a quantum gas microscope.

    Near-term quantum computations are susceptible to noise that — left uncorrected — can destroy the correlations responsible for quantum computational speedups. New work develops tools for bolstering the noise resilience of these speedups.

    Novel non-equilibrium phases of matter have recently become the focus of intense interest. The realization of topological phases which cannot exist under the constraints of thermodynamic equilibrium is a key aim.

    An elegant experiment showing that acoustic waves are amplified after scattering by a rotating body demonstrates an effect predicted in 1971 by Yakov Zel’dovich. This result has implications for the understanding of scattering from black holes.

    The quantum Hall effect is realized in a two-dimensional quantum gas system consisting of one spatial dimension and one synthetic dimension encoded in the atomic spin. Measurements show distinct bulk properties rooted in the topological structure.

    The spin polarization of a quantum Hall system is determined by a spin-resolved tunnelling method. This technique shows a substantial regime where the weakly interacting composite fermion picture is not valid.

    A memory device is proposed that uses a dynamical modification of the stacking order of few-layer WTe2 to encode information. The change in stacking modifies both the Berry curvature and the Hall transport, allowing two states to be distinguished.

    Uncorrected noise prevents quantum computers from running deep algorithms and outperforming classical machines. A method is now reported that allows noisy shallow quantum algorithms to be used to solve classically hard problems.

    An adaptive heterodyne technique with a Josephson parametric amplifier detector allows a high-precision single-shot canonical phase measurement on a one-photon wave packet, complementing near-ideal measurements of photon number or field amplitude.

    Standard topological invariants commonly used in static systems are not enough to fully capture the topological properties of Floquet systems. In a periodically driven quantum gas, chiral edge modes emerge despite all Chern numbers being equal to zero.

    Acoustic waves that carry orbital angular momentum are amplified as they pass through an absorbing disk when the rotation rate exceeds the frequency of the incident wave, thus providing an experimental demonstration of Zel’dovich amplification.

    The structures of stingers of living organisms are surprisingly similar despite their vastly different lengths. Now, stingers are found to obey a unifying mechanistic principle that characterizes the stingers resistance to buckling.
