  1. 1030. On the complexity of shallow quantum circuits with and without noise

    Invited Speaker / Conférencier(ère) invité(e)

    What computational problems can be solved efficiently with quantum computers, but not with classical computers? One of the most well understood examples of a problem that exhibits such a quantum computational advantage is sampling from quantum circuits. Based on a growing body of theoretical evidence, the problem of sampling from deep, random quantum circuits is now believed to be classically...

    The second-ordered anti-coherent state is known to achieve the ultimate limit for sensing rotation around an unknown axis, thereby saturating the quantum Cramér-Rao bound. It is convenient to map these states into an angular-momentum basis. Limited to measuring a small rotation angle, a corresponding set of bases has also been selected, postulated to provide the ultimate precision in rotation...

  3. 624. Adaptively Reconstructing a Quantum State Using Artificial Neural Networks

    Division for Quantum Information / Division de l'information quantique (DQI / DIQ)
    Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

    Quantum state tomography (QST) aims to reconstruct an unknown quantum state from measurement statistics and is a central tool for characterization and validation in quantum information and quantum computing. A key practical limitation in QST is sample cost: reconstructing a quantum state requires data from an informationally complete measurement set, and the number of distinct measurement...

  4. 647. Thermalization of a quantum circuit

    Thermalization is a common phenomenon in classical statistical mechanics. We encounter this every time we pour milk into a coffee cup or release a gas into a larger volume. The system loses the memory of its initial conditions and achieves the equilibrium statistical value. Quantum systems normally display a unitary evolution in the time-dependent case. I show an application of the arguments...
