Recovery of damaged information via scrambling in indefinite casual order
Tian-Ren Jin, Tian-Ming Li, Zheng-An Wang +3
Scrambling prevents the access to local information with local operators and therefore can be used to protect quantum information from damage caused by local perturbations. Even th…
Probing spin hydrodynamics on a superconducting quantum simulator
Yun-Hao Shi, Zheng-Hang Sun, Yong-Yi Wang +20
Characterizing the nature of hydrodynamical transport properties in quantum dynamics provides valuable insights into the fundamental understanding of exotic non-equilibrium phases…
Variational generation of spin squeezing on one-dimensional quantum devices with nearest-neighbor interactions
Zheng-Hang Sun, Yong-Yi Wang, Yu-Ran Zhang +2
Efficient preparation of spin-squeezed states is important for quantum-enhanced metrology. Current protocols for generating strong spin squeezing rely on either high dimensionality…
Logarithmic light cone, slow entanglement growth, and quantum memory
Yu Zeng, Alioscia Hamma, Yu-Ran Zhang +4
Effective light cones, characterized by Lieb-Robinson bounds, emerge in nonrelativistic local quantum systems. Here, we present several analytical results derived from logarithmic…
Metrological detection of multipartite entanglement through dynamical symmetries
Yu-Ran Zhang, Franco Nori
Multipartite entanglement, characterized by the quantum Fisher information (QFI), plays a central role in quantum-enhanced metrology and understanding quantum many-body physics. Wi…
Nonmesonic Quantum Many-Body Scars in a 1D Lattice Gauge Theory
Zi-Yong Ge, Yu-Ran Zhang, Franco Nori
We investigate the meson excitations (particle-antiparticle bound states) in quantum many-body scars of a 1D lattice gauge theory coupled to a dynamical spin-$\frac{…
