<jats:title>Abstract</jats:title><jats:p>Device-independent quantum key distribution (DIQKD) enables the generation of secret keys over an untrusted channel using uncharacterized and potentially untrusted devices<jats:sup>1–9</jats:sup>. The proper and secure functioning of the devices can be certified by a statistical test using a Bell inequality<jats:sup>10–12</jats:sup>. This test originates from the foundations of quantum physics and also ensures robustness against implementation loopholes<jats:sup>13</jats:sup>, thereby leaving only the integrity of the users’ locations to be guaranteed by other means. The realization of DIQKD, however, is extremely challenging—mainly because it is difficult to establish high-quality entangled states between two remote locations with high detection efficiency. Here we present an experimental system that enables for DIQKD between two distant users. The experiment is based on the generation and analysis of event-ready entanglement between two independently trapped single rubidium atoms located in buildings 400 metre apart<jats:sup>14</jats:sup>. By achieving an entanglement fidelity of <jats:inline-formula><jats:alternatives><jats:tex-math>$$ {\mathcal F} \,\ge 0.892(23)$$</jats:tex-math><mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mrow> <mml:mi>ℱ</mml:mi> <mml:mspace /> <mml:mo>≥</mml:mo> <mml:mn>0.892</mml:mn> <mml:mrow> <mml:mo>(</mml:mo> <mml:mrow> <mml:mn>23</mml:mn> </mml:mrow> <mml:mo>)</mml:mo> </mml:mrow> </mml:mrow> </mml:math></jats:alternatives></jats:inline-formula> and implementing a DIQKD protocol with random key basis<jats:sup>15</jats:sup>, we observe a significant violation of a Bell inequality of <jats:italic>S</jats:italic> = 2.578(75)—above the classical limit of 2—and a quantum bit error rate of only 0.078(9). For the protocol, this results in a secret key rate of 0.07 bits per entanglement generation event in the asymptotic limit, and thus demonstrates the system’s capability to generate secret keys. Our results of secure key exchange with potentially untrusted devices pave the way to the ultimate form of quantum secure communications in future quantum networks.</jats:p>

<jats:title>Abstract</jats:title><jats:p>Detailed knowledge of how diversity in the sequence of the human genome affects phenotypic diversity depends on a comprehensive and reliable characterization of both sequences and phenotypic variation. Over the past decade, insights into this relationship have been obtained from whole-exome sequencing or whole-genome sequencing of large cohorts with rich phenotypic data<jats:sup>1,2</jats:sup>. Here we describe the analysis of whole-genome sequencing of 150,119 individuals from the UK Biobank<jats:sup>3</jats:sup>. This constitutes a set of high-quality variants, including 585,040,410 single-nucleotide polymorphisms, representing 7.0% of all possible human single-nucleotide polymorphisms, and 58,707,036 indels. This large set of variants allows us to characterize selection based on sequence variation within a population through a depletion rank score of windows along the genome. Depletion rank analysis shows that coding exons represent a small fraction of regions in the genome subject to strong sequence conservation. We define three cohorts within the UK Biobank: a large British Irish cohort, a smaller African cohort and a South Asian cohort. A haplotype reference panel is provided that allows reliable imputation of most variants carried by three or more sequenced individuals. We identified 895,055 structural variants and 2,536,688 microsatellites, groups of variants typically excluded from large-scale whole-genome sequencing studies. Using this formidable new resource, we provide several examples of trait associations for rare variants with large effects not found previously through studies based on whole-exome sequencing and/or imputation.</jats:p>
