<jats:title>Abstract</jats:title><jats:p>Realizing the potential of quantum computing requires sufficiently low logical error rates<jats:sup>1</jats:sup>. Many applications call for error rates as low as 10<jats:sup>−15</jats:sup> (refs. <jats:sup>2–9</jats:sup>), but state-of-the-art quantum platforms typically have physical error rates near 10<jats:sup>−3</jats:sup> (refs. <jats:sup>10–14</jats:sup>). Quantum error correction<jats:sup>15–17</jats:sup> promises to bridge this divide by distributing quantum logical information across many physical qubits in such a way that errors can be detected and corrected. Errors on the encoded logical qubit state can be exponentially suppressed as the number of physical qubits grows, provided that the physical error rates are below a certain threshold and stable over the course of a computation. Here we implement one-dimensional repetition codes embedded in a two-dimensional grid of superconducting qubits that demonstrate exponential suppression of bit-flip or phase-flip errors, reducing logical error per round more than 100-fold when increasing the number of qubits from 5 to 21. Crucially, this error suppression is stable over 50 rounds of error correction. We also introduce a method for analysing error correlations with high precision, allowing us to characterize error locality while performing quantum error correction. Finally, we perform error detection with a small logical qubit using the 2D surface code on the same device<jats:sup>18,19</jats:sup> and show that the results from both one- and two-dimensional codes agree with numerical simulations that use a simple depolarizing error model. These experimental demonstrations provide a foundation for building a scalable fault-tolerant quantum computer with superconducting qubits.</jats:p>

<jats:title>Abstract</jats:title><jats:p>Denisova Cave in southern Siberia is the type locality of the Denisovans, an archaic hominin group who were related to Neanderthals<jats:sup>1–4</jats:sup>. The dozen hominin remains recovered from the deposits also include Neanderthals<jats:sup>5,6</jats:sup> and the child of a Neanderthal and a Denisovan<jats:sup>7</jats:sup>, which suggests that Denisova Cave was a contact zone between these archaic hominins. However, uncertainties persist about the order in which these groups appeared at the site, the timing and environmental context of hominin occupation, and the association of particular hominin groups with archaeological assemblages<jats:sup>5,8–11</jats:sup>. Here we report the analysis of DNA from 728 sediment samples that were collected in a grid-like manner from layers dating to the Pleistocene epoch. We retrieved ancient faunal and hominin mitochondrial (mt)DNA from 685 and 175 samples, respectively. The earliest evidence for hominin mtDNA is of Denisovans, and is associated with early Middle Palaeolithic stone tools that were deposited approximately 250,000 to 170,000 years ago; Neanderthal mtDNA first appears towards the end of this period. We detect a turnover in the mtDNA of Denisovans that coincides with changes in the composition of faunal mtDNA, and evidence that Denisovans and Neanderthals occupied the site repeatedly—possibly until, or after, the onset of the Initial Upper Palaeolithic at least 45,000 years ago, when modern human mtDNA is first recorded in the sediments.</jats:p>
