• Abstract: We study the equivalence of mixed states under local unitary transformations. First we express quantum states in Bloch representation. Then based on the coefficient matrices, some invariants are constructed. This method and results can be extended to multipartite high dimensional system.

  The dimension of a quantum state is traditionally seen as the number of superposed distinguishable states in a given basis. We propose an absolute, i.e.basis-independent, notion of dimensionality for ensembles of quantum states.

  We propose a highly efficient algorithm that converts fermionic Gaussian states to matrix product states. It can be formulated for finite-size systems without translation invariance, but becomes particularly appealing when applied to infinite systems. The potential of our method is demonstrated by numerical calculations in two chiral spin liquids.

  Local unitary equivalence is an ingredient for quantifying and classifying entanglement. We find a variety of local unitary invariants for arbitrary-dimensional bipartite quantum states. We apply these invariants to estimate concurrence, a vital entanglement measure.

  We show the ability to restore states of quantum systems from evolution induced by quantum dynamical semigroups perturbed by covariant measures. Our procedure describes reconstruction of quantum states transmitted via quantum channels and as a particular example can be applied to reconstruction of photonic states transmitted via optical fibers.

• Covariant operator bases for continuous variables [0.0]
  We work out an alternative basis consisting of monomials on the basic observables, with the crucial property of behaving well under symplectic transformations. Given the density matrix of a state, the expansion coefficients in that basis constitute the multipoles, which describe the state in a canonically covariant form that is both concise and explicit.

  We show how to encode data into quantum states with amplitudes growing exponentially in the system size. We propose an embedding circuit for generating the orthonormal Chebyshev basis of exponential capacity. This enables automatic model differentiation, and opens a route to solving differential equations.

  We show that the covariance matrix of a quantum state can be reconstructed from position measurements using the simple notion of polar duality. All multidimensional Gaussian states (pure or mixed) can in principle be reconstructed if the quantum system is well localized in configuration space.

  We define two mixed states to be in the same phase if both states can be transformed into the other by a shallow circuit of local quantum channels. We first construct families of such states based on C*-weak Hopf algebras, the algebras whose representations form a fusion category. More concretely, we provide explicit local fine-graining and local coarse-graining quantum channels for the renormalization procedure of these states.

• Stochastic approximate state conversion for entanglement and general quantum resource theories [41.94295877935867]
  An important problem in any quantum resource theory is to determine how quantum states can be converted into each other. Very few results have been presented on the intermediate regime between probabilistic and approximate transformations. We show that these bounds imply an upper bound on the rates for various classes of states under probabilistic transformations. We also show that the deterministic version of the single copy bounds can be applied for drawing limitations on the manipulation of quantum channels.
