چکیده
We discuss the variational optimization of a unitary tensor-network circuit with different network structures. The ansatz is performed based on generalization well-developed multi-scale entanglement renormalization algorithm and also conjugate-gradient method an effective line search. present benchmarking calculations for structures by studying Heisenberg model in strongly disordered magnetic field $QR$-decomposition.

Optimization Schemes For Wireless Sensor Network Localization
Many applications of wireless sensor networks (WSN) require information about the geographical location of each sensor node. Self-organization and localization capabilities are one of the most important requirements in sensor networks. This paper provides an overview of centralized distance-based algorithms for estimating the positions of nodes in a sensor network. We discuss and compare three ...
متن کاملUniversal gates for non-unitary quantum circuit
Quantum circuit is generalized to include non-unitary gates which are operated by quantum measurement. A 1-qubit non-unitary gate, together with the controlled-NOT gate and the 1-qubit unitary gate, is shown to constitute a universal set of gates for the non-unitary quantum circuit that reduces the number of the overhead of qubits required to ensure fault tolerance. A reversing measurement sche...
متن کاملUnitary-circuit semantics for measurement-based computations
One-way measurement based quantum computations (1WQC) may describe unitary transformations, via a composition of CPTP maps which are not all unitary themselves. This motivates the following decision problems: Is it possible to determine whether a “quantum-to-quantum” 1WQC procedure (having non-trivial input and output subsystems) performs a unitary transformation? Is it possible to describe pre...
متن کاملA non-unitary quantum circuit
The quantum circuit is generalized to include non-unitary gates operated by quantum measurement, in order to reduce the number of the overhead of qubits required to ensure fault tolerance. A specific type of one-qubit non-unitary gates, together with the controlled-not gate and all one-qubit unitary gates, is shown to constitute a universal set of gates for the non-unitary quantum circuit. A re...
متن کاملSome Combinatorial Optimization Schemes for Multi-Layer Network Topology
The article addresses combinatorial optimization schemes for design of multi-layer communication network topology. The paper consists of three parts: (a) description of system issues as basic requirements, trends (e.g., evolution, upgradeability), and a ”system space” for contemporary network design; (b) brief description of some basic combinatorial optimization problems as follows: multicriter...
