public static makeTupleOfQureg(qubits: Qubit | Qubit[] | Qureg | Qureg[]): Qureg[] source

Convert quantum input of "gate | quantum input" to internal formatting.

A Command object only accepts tuples of Quregs (list of Qubit objects) as qubits input parameter. However, with this function we allow the user to use a more flexible syntax:

where qubit is a Qubit object and qureg is a Qureg object. This function takes the right hand side of | and transforms it to the correct input parameter of a Command object which is:

Params:

Name	Type	Attribute	Description
qubits	Qubit \| Qubit[] \| Qureg \| Qureg[]		a Qubit object, a list of Qubit objects, a Qureg object, or a tuple of Qubit or Qureg objects (can be mixed).

Return:

Qureg[]

Canonical representation A tuple containing Qureg (or list of Qubits) objects.

Public Constructors

public constructor() source

Example:

ExampleGate | (a,b,c,d,e)

where a and b are interchangeable. Then, call this function as
follows:

this.set_interchangeable_qubit_indices([[0,1]])

As another example, consider

ExampleGate2 | (a,b,c,d,e)

where a and b are interchangeable and, in addition, c, d, and e
are interchangeable among themselves. Then, call this function as

this.set_interchangeable_qubit_indices([[0,1],[2,3,4]])

Public Methods

public copy(): BasicGate source

Return:

BasicGate

public equal(other: BasicGate | Object): boolean source

Params:

Name	Type	Attribute	Description
other	BasicGate \| Object

Return:

boolean

public generateCommand(qubits: *): Command source

Helper function to generate a command consisting of the gate and the qubits being acted upon.

Params:

Name	Type	Attribute	Description
qubits	*		{Qubit \| Array.<Qubit> \| Qureg} see BasicGate.makeTupleOfQureg(qubits)

Return:

Command

A Command object containing the gate and the qubits.

public getInverse() source

Throw:

Error

public getMerged() source

Throw:

NotMergeable

public inspect(): string source

Return:

string

public or(qubits: *) source

Operator| overload which enables the syntax Gate | qubits.

Params:

Name	Type	Attribute	Description
qubits	*		{Qubit \| Array.<Qubit> \| Qureg} a Qubit object, a list of Qubit objects, a Qureg object, or a tuple of Qubit or Qureg objects (can be mixed).

Example:

1) Gate | qubit
2) Gate | [qubit0, qubit1]
3) Gate | qureg
4) Gate | (qubit, )
5) Gate | (qureg, qubit)
