Quantum Genetic Optimization
It is shown that the complexity of the quantum genetic optimization algorithm (QGOA) is in terms of number of oracle calls in the selection procedure, which is confirmed by the simulations of the algorithm.
Toward an architecture for quantum programming
A template high level quantum language is presented which complements a generic general purpose classical language with a set of quantum primitives, and easily lends itself to automatic, hardware independent, circuit simplification.
Quantum information processing and communication
Abstract.We present an excerpt of the document “Quantum Information Processing and Communication: Strategic report on current status, visions and goals for research in Europe”, which has been
Chopped random-basis quantum optimization
The efficiency of the chopped random basis optimal control technique in optimizing different quantum processes is studied and it is shown that in the considered cases it obtain results equivalent to those obtained via different optimal control methods while using less resources.
Optimal control of complex atomic quantum systems
This work computing theoretically and verifying experimentally the optimal transformations in two very different interacting systems: the coherent manipulation of motional states of an atomic Bose-Einstein condensate and the crossing of a quantum phase transition in small systems of cold atoms in optical lattices.
Optimal control at the quantum speed limit.
This work explores the ultimate limit in paradigmatic cases of optimal control theory, and demonstrates that it coincides with the maximum speed limit allowed by quantum evolution.
Optimal control technique for many-body quantum dynamics.
We present an efficient strategy for controlling a vast range of nonintegrable quantum many-body one-dimensional systems that can be merged with state-of-the-art tensor network simulation methods
Positive Tensor Network Approach for Simulating Open Quantum Many-Body Systems.
This work introduces a versatile and practical method to numerically simulate one-dimensional open quantum many-body dynamics using tensor networks, based on representing mixed quantum states in a locally purified form, which guarantees that positivity is preserved at all times.
Microwave potentials and optimal control for robust quantum gates on an atom chip
We propose a two-qubit collisional phase gate that can be implemented with available atom chip technology and present a detailed theoretical analysis of its performance. The gate is based on earlier
Training Schrödinger’s cat: quantum optimal control
In this communication, state-of-the-art quantum control techniques are reviewed and put into perspective by a consortium of experts in optimal control theory and applications to spectroscopy, imaging, as well as quantum dynamics of closed and open systems.
