Hybrid classical-quantum dynamics

On Hybrid Dynamics of the Copenhagen Dichotomic World

In the Copenhagen viewpoint, part of the world is quantized and the complementary part remains classical. From a formal dynamic aspect, standard theory is incomplete since it does never account for the so-called ’back-reaction’ of quantized systems on classical systems except for the highly idealized system–detector interaction. To resolve this formal issue, a certain ’hybrid dynamics’ can be c...

General approach to quantum-classical hybrid systems and geometric forces.

We present a general theoretical framework for a hybrid system that is composed of a quantum subsystem and a classical subsystem. We approach such a system with a simple canonical transformation which is particularly effective when the quantum subsystem is dynamically much faster than the classical counterpart, which is commonly the case in hybrid systems. Moreover, this canonical transformatio...

مروری بر شبکه­ های عصبی کوانتومی

In this paper the development of quantum neural networks (QNN), and some of presented models and physical implementation are reviewed. How of making use of double-slit experiment for implementing QNN and methods of designing as well as examples of two-layer hybrid networks in QNN constructed from quantum neurons and classical neurons are represented. Some application models of the networks (QNN...

Greater gait with gravity

Making a quantumclassical hybrid Predicting the dynamics of many-body quantum systems is a formidable computational task, in which quantum computers could come to the aid of classical ones. However, the corrections needed to keep errors in check as a quantum computer works require enormous quantum resources. Li and Benjamin propose a hybrid quantum-classical computer based on variational princi...
