• Abstract summary: Entangled quantum states that are symmetric to permutation between qubits are of growing interest. We present protocols for the creation of different symmetric states including Schrodinger cat and Gottesman-Kitaev-Preskill states. The obtained symmetric states can be transferred to traveling photonic states via spontaneous emission.

• Abstract: The manipulation of quantum many-body systems is a frontier challenge in quantum science. Entangled quantum states that are symmetric to permutation between qubits are of growing interest. Yet, the creation and control of symmetric states has remained a challenge. Here, we find a way to universally control symmetric states, proposing a scheme that relies solely on coherent rotations and spin squeezing. We present protocols for the creation of different symmetric states including Schrodinger cat and Gottesman-Kitaev-Preskill states. The obtained symmetric states can be transferred to traveling photonic states via spontaneous emission, providing a powerful mechanism for the creation of desired quantum light states.

  We show that the information-theoretic characteristics of anyons diverge fundamentally from those of non-anyonic systems. In bipartite anyonic systems, pure states may have different marginal spectra, and mixed states may contain pure marginal states. Our findings significantly advance the understanding of the information-theoretic aspects of anyons and may lead to realizations of quantum communication and cryptographic protocols.

• Second Law of Entanglement Manipulation with Entanglement Battery [41.94295877935867]
  A central question since the beginning of quantum information science is how two distant parties can convert one entangled state into another. It has been conjectured that entangled state transformations could be executed reversibly in an regime, mirroring the nature of Carnot cycles in classical thermodynamics. We investigate the concept of an entanglement battery, an auxiliary quantum system that facilitates quantum state transformations without a net loss of entanglement.

This unique coupling is found to enable control over the equilibrium magnon squeezing and a deterministic generation of squeezed even Fock states.
