Detailed Description

A gate simulation implementation of gate_simulation_func.

This functor performs simulation on a boost::dynamic_bitset<> for Toffoli, Fredkin, and Peres gates for binary values only.

When adding new simulation functors, you can make use of this one, for example when extending the gate library. Note, that you do not have to derive from this class for this purpose, but can use the following:

// somewhere a new target tag
struct my_gate_tag {};

bool is_my_gate( const gate& g )
{
  return is_type<my_gate>( g.type() );
}

// ...

// extend simulation
struct extended_gate_simulation
{

  boost::dynamic_bitset<>& operator()( const gate& g, boost::dynamic_bitset<>& input ) const
  {
    if ( is_my_gate( g )
    {
      // change input according to the semantics of the new gate type
      // ...
      // and return it finally
      return input;
    }
    else
    {
      // it is a core gate
      return core_simulation( g, input );
    }
  }

private:
  core_gate_simulation core_simulation;
};

// use it somewhere
circuit circ( ... );  // some circuit with my_gate gates

boost::dynamic_bitset<> output;
boost::dynamic_bitset<> input( 4, 10 );   // value 1010

properties::ptr settings( new properties() );
settings.set( "gate_simulation", extended_gate_simulation() );

simple_simulation( output, circ, input, settings );

boost::dynamic_bitset& operator()	(	const gate &	g,
		boost::dynamic_bitset<> &	input
	)		const

Simulation for a single gate g.

This operator performs simulation for a single gate and is called by simple_simulation.

Important: The return value always has to be input, and the operator should modify input directly.

Parameters

g	The gate to be simulated
input	An input pattern

Returns

Returns a output pattern, it will be the same reference as input
