Constructor Detail

QubitVertex

public QubitVertex()

Upon construction, a qubit vertex is initialised with the Hadamard operation as VOp, and with empty neighbor list. This makes it represent a state |0>.

Method Detail

getMatrix

public double[][][] getMatrix()

Returns the complex 2x2 matrix representing the vertex operator associated to this qubit vertex, according to the graph state formalism.

Returns:

the complex 2x2 matrix representing the vertex operator associated to this qubit vertex

equals

public boolean equals(Object o)

Compares the specified object with this qubit vertex. Two qubit vertices are the same if and only if they are represented by the same local Clifford operator.

Overrides:

equals in class Object

Returns:

true if and only if the specified object represents a physically equivalent qubit vertex than this vertex

hashCode

public int hashCode()

Returns the hash code for this qubit vertex.

Overrides:

hashCode in class Object

Returns:

the hash code for this qubit vertex

toString

public String toString()

Overrides:

toString in class Object
