        <string language="fre"><![CDATA[In    the    algebraic    approach    to    quantum    field    theory    on    curved    backgrounds, there    exists    a    special    class    of    quantum    states    for    free    fields, called    of    Hadamard    form. These    are    of    particular    relevance    since    they    yield    finite    quantum    fluctuations    of    all observables    and    they    can    be    used    to    implement    interactions    at    a    perturbative    level. Although    their    existence    is    guaranteed    on    all    globally    hyperbolic    spacetimes, for    long time    only    few    explicit    examples    were    known.    A    way    to    bypass    this    problem    exists    on those    manifolds    which    possess    a    null    conformal    boundary,    such    as    all    asymptotically    flat spacetimes.    In    this    talk    we    shall    discuss    this    construction    in    particular    for    massless, conformally    coupled    scalar    fields    and    for    linearised    gravity.]]></string></description>
