<jats:title>Abstract</jats:title><jats:p>Measurement has a special role in quantum theory<jats:sup>1</jats:sup>: by collapsing the wavefunction, it can enable phenomena such as teleportation<jats:sup>2</jats:sup> and thereby alter the ‘arrow of time’ that constrains unitary evolution. When integrated in many-body dynamics, measurements can lead to emergent patterns of quantum information in space–time<jats:sup>3–10</jats:sup> that go beyond the established paradigms for characterizing phases, either in or out of equilibrium<jats:sup>11–13</jats:sup>. For present-day noisy intermediate-scale quantum (NISQ) processors<jats:sup>14</jats:sup>, the experimental realization of such physics can be problematic because of hardware limitations and the stochastic nature of quantum measurement. Here we address these experimental challenges and study measurement-induced quantum information phases on up to 70 superconducting qubits. By leveraging the interchangeability of space and time, we use a duality mapping<jats:sup>9,15–17</jats:sup> to avoid mid-circuit measurement and access different manifestations of the underlying phases, from entanglement scaling<jats:sup>3,4</jats:sup> to measurement-induced teleportation<jats:sup>18</jats:sup>. We obtain finite-sized signatures of a phase transition with a decoding protocol that correlates the experimental measurement with classical simulation data. The phases display remarkably different sensitivity to noise, and we use this disparity to turn an inherent hardware limitation into a useful diagnostic. Our work demonstrates an approach to realizing measurement-induced physics at scales that are at the limits of current NISQ processors.</jats:p>

Structure and electromechanical coupling of a voltage-gated Na+/H+ exchanger
Hyunku Yeo; Ved Mehta; Ashutosh Gulati; David Drew
<jats:title>Abstract</jats:title><jats:p>Voltage-sensing domains control the activation of voltage-gated ion channels, with a few exceptions<jats:sup>1</jats:sup>. One such exception is the sperm-specific Na<jats:sup>+</jats:sup>/H<jats:sup>+</jats:sup> exchanger SLC9C1, which is the only known transporter to be regulated by voltage-sensing domains<jats:sup>2–5</jats:sup>. After hyperpolarization of sperm flagella, SLC9C1 becomes active, causing pH alkalinization and CatSper Ca<jats:sup>2+</jats:sup> channel activation, which drives chemotaxis<jats:sup>2,6</jats:sup>. SLC9C1 activation is further regulated by cAMP<jats:sup>2,7</jats:sup>, which is produced by soluble adenyl cyclase (sAC). SLC9C1 is therefore an essential component of the pH–sAC–cAMP signalling pathway in metazoa<jats:sup>8,9</jats:sup>, required for sperm motility and fertilization<jats:sup>4</jats:sup>. Despite its importance, the molecular basis of SLC9C1 voltage activation is unclear. Here we report cryo-electron microscopy (cryo-EM) structures of sea urchin SLC9C1 in detergent and nanodiscs. We show that the voltage-sensing domains are positioned in an unusual configuration, sandwiching each side of the SLC9C1 homodimer. The S4 segment is very long, 90 Å in length, and connects the voltage-sensing domains to the cytoplasmic cyclic-nucleotide-binding domains. The S4 segment is in the up configuration—the inactive state of SLC9C1. Consistently, although a negatively charged cavity is accessible for Na<jats:sup>+</jats:sup> to bind to the ion-transporting domains of SLC9C1, an intracellular helix connected to S4 restricts their movement. On the basis of the differences in the cryo-EM structure of SLC9C1 in the presence of cAMP, we propose that, upon hyperpolarization, the S4 segment moves down, removing this constriction and enabling Na<jats:sup>+</jats:sup>/H<jats:sup>+</jats:sup> exchange.</jats:p>
