Efficient Algorithm for Optimal Control of Mixed-State Quantum Systems
Much work has recently been done on control of pure-state quantum systems using the traditional wavefunction formalism [?,?,?]. This work is most important; however many physical systems, such as systems initially in thermal equilibrium or otherwise described by an ensemble of states, or systems where dissipative processes are significant, can not be treated using this approach. Therefore, a de...
متن کاملTime-optimal control by a quantum actuator
Indirect control of qubits by a quantum actuator has been proposed as an appealing strategy to manipulate qubits that couple only weakly to external fields. While universal quantum control can be easily achieved when the actuator-qubit coupling is anisotropic, the efficiency of this approach is less clear. Here we analyze the time efficiency of quantum actuator control. We describe a strategy t...
متن کاملParallelized quantum Monte Carlo algorithm with nonlocal worm updates.
Based on the worm algorithm in the path-integral representation, we propose a general quantum Monte Carlo algorithm suitable for parallelizing on a distributed-memory computer by domain decomposition. Of particular importance is its application to large lattice systems of bosons and spins. A large number of worms are introduced and its population is controlled by a fictitious transverse field. ...
متن کاملUsing Modified IPSO-SQP Algorithm to Solve Nonlinear Time Optimal Bang-Bang Control Problem
In this paper, an intelligent-gradient based algorithm is proposed to solve time optimal bang-bang control problem. The proposed algorithm is a combination of an intelligent algorithm called improved particle swarm optimization algorithm (IPSO) in the first stage of optimization process together with a gradient-based algorithm called successive quadratic programming method (SQP) in the second s...
متن کاملOptimal Finite-time Control of Positive Linear Discrete-time Systems
This paper considers solving optimization problem for linear discrete time systems such that closed-loop discrete-time system is positive (i.e., all of its state variables have non-negative values) and also finite-time stable. For this purpose, by considering a quadratic cost function, an optimal controller is designed such that in addition to minimizing the cost function, the positivity proper...
