• Abstract: Quantum correlation is a fundamental property which distinguishes quantum systems from classical ones, and it is also a fragile resource under projective measurement. Recently, it has been shown that a subsystem in entangled pairs can share nonlocality with multiple observers in sequence. Here we present a new steering scenario where both subsystems are accessible by multiple observers. And it is found that the two qubits in singlet state can be simultaneously steered by two sequential observers, respectively.

• Unbounded sequential multipartite nonlocality via violation of Mermin inequality [0.0]
  Quantum nonlocality is a significant feature in quantum information theory. We study sequential nonlocality in systems comprising more parties and observer chains. Our results suggest that increasing the number of subsystems may enable more observer chains to detect nonlocality alongside single observers.

  Isolated interacting quantum systems generally thermalize, yet there are several counterexamples for the breakdown of ergodicity. Recently, ergodicity breaking has been observed in systems subjected to linear potentials, termed Stark many-body localization. Here, we experimentally explore initial-state dependent dynamics using a ladder-type superconducting processor with up to 24 qubits.

• Dimension-independent weak value estimation via controlled SWAP operations [1.2289361708127877]
  We propose a dimension-independent scheme for estimating weak values of arbitrary observables. The scheme is based on controlled SWAP operations and associates states and observables in the mathematical expression of the weak value. It provides insights into the relation between states of two identical quantum systems at a single moment of time and states of a single quantum system at two moments of time, also known as two-time states.

  In the quantum Zeno effect, quantum measurements can block the coherent oscillation of a two level system by freezing its state to one of the measurement eigenstates. We show that the onset of the Zeno regime is marked by a $textitcascade of transitions$ in the system dynamics as the measurement strength is increased.
