چکیده
Quantum battery is one of the most prominent micro-devices in rapid-developing quantum thermodynamics. We propose a charging protocol which both and charger are consisted many-spin system. The connected via Kittle mode magnon system, that serves as wire then enables long-range protocol. Counter-intuitively, we find spin-spin couplings insider can be used to promote performance comparison noninteracting condition. And remarkable promotion realized at "sweet" spot terms average coupling strength. Moreover, apply quantum-state-diffusion equation test robustness our magnon-mediated systematic errors about frequency.

Quantum deformed magnon kinematics
The dispersion relation for planar N = 4 supersymmetric Yang-Mills is identified with the Casimir of a quantum deformed two-dimensional kinematical symmetry, Eq(1, 1). The quantum deformed symmetry algebra is generated by the momentum, energy and boost, with deformation parameter q = e. Representing the boost as the infinitesimal generator for translations on the rapidity space leads to an elli...
متن کاملErrors in quantum tomography: diagnosing systematic versus statistical errors
A prime goal of quantum tomography is to provide quantitatively rigorous characterization of quantum systems, be they states, processes or measurements, particularly for the purposes of trouble-shooting and benchmarking experiments in quantum information science. A range of techniques exist to enable the calculation of errors, such as Monte-Carlo simulations, but their quantitative value is arg...
متن کاملMagnon decay in gapped quantum spin systems.
In the continuum O(3) sigma-model description of gapped spin systems, S = 1 magnons can only decay into three lower energy magnons. We argue that the symmetry of the quantum spin Hamiltonian often allows decay into two magnons, and compute this decay rate in model systems. Two-magnon decay is present in Haldane gap S = 1 spin chains, even though it cannot be induced by any allowed term written ...
متن کاملSystematic errors in current quantum state tomography tools.
Common tools for obtaining physical density matrices in experimental quantum state tomography are shown here to cause systematic errors. For example, using maximum likelihood or least squares optimization to obtain physical estimates for the quantum state, we observe a systematic underestimation of the fidelity and an overestimation of entanglement. Such strongly biased estimates can be avoided...
متن کاملHow to counteract systematic errors in quantum state transfer
In the absence of errors, the dynamics of a spin chain, with a suitably engineered local Hamiltonian, allow the perfect, coherent transfer of a quantum state over large distances. Here, we propose encoding and decoding procedures to recover perfectly from low rates of systematic errors. The encoding and decoding regions, located at opposite ends of the chain, are small compared to the length of...
