• Abstract: The postulates of von Neumann and L\"uders concerning measurements in quantum mechanics are discussed and criticized in the context of a simple model proposed by Gisin. The main purpose of our paper is to analyze some mathematical aspects of that model and to draw some general lessons on the so-called ``measurement problem'' in quantum mechanics pointing towards the need to introduce general principles that determine the law for the stochastic time evolution of states of individual physical systems.

  We present a framework for quantum work statistics in continuously monitored quantum systems. Our approach naturally incorporates non-Hermitian dynamics arising from quantum jump processes. We illustrate our theoretical framework by analyzing a one-dimensional transverse-field Ising model under local spin monitoring.

We apply Trotter methods to obtain results for the complexity of adiabatic ground state preparation in both the weak-coupling and quantum-critical regimes. We present and analyze a quantum algorithm based on non-unitary randomized simulation methods.
