  text: "<jats:p>We report on a photonic simulator of the critical state forming at
    the quantum phase transition between topologically distinct Anderson insulator
    phases. We observe a time-staggered profile in the circular photon polarization,
    which originates from the interplay of a chiral and sublattice symmetry, and has
    recently been suggested as a signature for topological Anderson criticality within
    the setup. We discuss the role of statistical detuning from criticality and show
    that the controlled breaking of phase coherence removes the signal, revealing
    its origin in quantum coherence.</jats:p>\r\n          <jats:sec>\r\n            <jats:title/>\r\n

  text: "<jats:p>The ability to apply user-chosen large-scale unitary operations with
    high fidelity to a quantum state is key to realizing future photonic quantum technologies.
    Here, we realize the implementation of programmable unitary operations on up to
    64 frequency-bin modes. To benchmark the performance of our system, we probe different
    quantum walk unitary operations, in particular, Grover walks on four-dimensional
    hypercubes with similarities exceeding 95% and quantum walks with 400 steps on
    circles and finite lines with similarities of 98%. Our results open a path toward
    implementing high-quality unitary operations, which can form the basis for applications
    in complex tasks, such as Gaussian boson sampling.</jats:p>\r\n          <jats:sec>\r\n

  text: In this article we prove meromorphic continuation of weighted zeta functions
    in the framework of open hyperbolic systems by using the meromorphically continued
    restricted resolvent of Dyatlov and Guillarmou (2016). We obtain a residue formula
    proving equality between residues of weighted zetas and invariant Ruelle distributions.
    We combine this equality with results of Guillarmou, Hilgert and Weich (2021)
    in order to relate the residues to Patterson-Sullivan distributions. Finally we
    provide proof-of-principle results concerning the numerical calculation of invariant
    Ruelle distributions for 3-disc scattering systems.

  text: In real photonic quantum systems losses are an unavoidable factor limiting
    the scalability to many modes and particles, restraining their application in
    fields as quantum information and communication. For this reason, a considerable
    amount of engineering effort has been taken in order to improve the quality of
    particle sources and system components. At the same time, data analysis and collection
    methods based on post-selection have been used to mitigate the effect of particle
    losses. This has allowed for investigating experimentally multi-particle evolutions
    where the observer lacks knowledge about the system's intermediate propagation
    states. Nonetheless, the fundamental question how losses affect the behaviour
    of the surviving subset of a multi-particle system has not been investigated so
    far. For this reason, here we study the impact of particle losses in a quantum
    walk of two photons reconstructing the output probability distributions for one
    photon conditioned on the loss of the other in a known mode and temporal step
    of our evolution network. We present the underlying theoretical scheme that we
    have devised in order to model controlled particle losses, we describe an experimental
    platform capable of implementing our theory in a time multiplexing encoding. In
    the end we show how localized particle losses change the output distributions
    without altering their asymptotic spreading properties. Finally we devise a quantum
    civilization problem, a two walker generalisation of single particle recurrence
    processes.

  text: In this paper we give an overview over some aspects of the modern mathematical
    theory of Ruelle resonances for chaotic, i.e. uniformly hyperbolic, dynamical
    systems and their implications in physics. First we recall recent developments
    in the mathematical theory of resonances, in particular how invariant Ruelle distributions
    arise as residues of weighted zeta functions. Then we derive a correspondence
    between weighted and semiclassical zeta functions in the setting of negatively
    curved surfaces. Combining this with results of Hilgert, Guillarmou and Weich
    yields a high frequency interpretation of invariant Ruelle distributions as quantum
    mechanical matrix coefficients in constant negative curvature. We finish by presenting
    numerical calculations of phase space distributions in the more physical setting
    of 3-disk scattering systems.

  text: Quantum walks function as essential means to implement quantum simulators,
    allowing one to study complex and often directly inaccessible quantum processes
    in controllable systems. In this contribution, the notion of a driven Gaussian
    quantum walk is introduced. In contrast to typically considered quantum walks
    in optical settings, we describe the operation of the walk in terms of a nonlinear
    map rather than a unitary operation, e.g., by replacing a beam-splitter-type coin
    with a two-mode squeezer, being a process that is controlled and driven by a pump
    field. This opens previously unattainable possibilities for quantum walks that
    include nonlinear elements as core components of their operation, vastly extending
    their range of applications. A full framework for driven Gaussian quantum walks
    is developed, including methods to dynamically characterize nonlinear, quantum,
    and quantum-nonlinear effects. Moreover, driven Gaussian quantum walks are compared
    with their classically interfering and linear counterparts, which are based on
    classical coherence of light rather than quantum superpositions. In particular,
    the generation and boost of highly multimode entanglement, squeezing, and other
    quantum effects are studied over the duration of the nonlinear walk. Importantly,
    we prove the quantumness of the evolution itself, regardless of the input state.
    A scheme for an experimental realization is proposed. Furthermore, nonlinear properties
    of driven Gaussian quantum walks are explored, such as amplification that leads
    to an ever increasing number of correlated quantum particles, constituting a source
    of new walkers during the walk. Therefore, a concept for quantum walks is proposed
    that leads to—and even produces—directly accessible quantum phenomena, and that
    renders the quantum simulation of nonlinear processes possible.
