System Class

[aarongrisez]

Feature

We need to code a base class for quantum systems. This will track the state of the quantum system and house all methods related to the system evolution/simulation.

Description

I think the best starting place here would be to emulate the system class already in the tests directory. See system.py for more details.

Here's an overview of simulator.hpp as it stands.

class Simulator {
private:
    _hamiltonian;
    _propagator;
    _psi0;
    _currentState;
    _setPropagator();
    _time;
    _size;
public:
    _init();
    _setSize();
    _setHamiltonian();
    _setPsi0();
    _runOneStep();
    _getCurrentStateSize();
    _getPropagatorRows();
    _getPropagatorCols();
    _getTime();
    _register_methods();
};

Remaining to implement:

private:
    _sampleDistribution();
    _createDensityMatrix();
    _tracePOVM();
    _updateState();
public:
    _getProbabilities();
    _setPOVM();
    _measure();

Things to move from public to private (or remove all together):

_getCurrentStateSize();
_getPropagatorRows();
_getPropagatorCols();
