Counterdiabatic Optimized Local Driving annealER

This package provides tool for spin system simulation and optimization through a combination of Quantum Optimal Control and Counterdiabatic Driving techniques, as in this reference paper. The framework allows to prompt the system through a simplified interface and automatically solve the minimization of the Adiabatic Gauge Potential (AGP) for a given local ansatz.

Package creator: Barone Francesco Pio, openlab summer 2023 intern

Supervisors: Oriel Kiss, Antonio Mandarino, Michele Grossi, Sofia Vallecorsa

Installation

To install this package, clone this repo and install through pip:

git clone https://github.com/CERN-IT-INNOVATION/colder
cd colder
pip install .

structure of the package

The colder package consists of the following modules:

• backend: implements the time evolution routines in different backends
• core: provides the I/O of spin model and the algebraic routines used for the symbolical optimization
• gauge: class that optimizes symbolically the AGP ansatz
• models: provides useful functions to specify the spin model interactions
• quantum: implements basic functions to manipulate quantum states, regardless of the backend
• simulation: implements the time evolution interface and the COLD object

Getting started

The Documentation of this package provides all the required information to use the physics interface and run annealing simulation & optimization.

A set of examples is provided in the examples folder.
