DaggerEngine

BasicEngine → DaggerEngine

Stores all commands and, when done, inverts the circuit & runs it.

Constructor Summary

Public Constructor
public	constructor()

Public Methods
public	receive(cmdList: Command[]) Receive a list of commands and store them for later inversion.
public	run() Run the stored circuit in reverse and check that local qubits have been deallocated.

From class BasicEngine
public	isLastEngine: boolean
public	allocateQubit(dirty: boolean): Qureg Return a new qubit as a list containing 1 qubit object (quantum register of size 1).
public	allocateQureg(n: number): Qureg Allocate n qubits and return them as a quantum register, which is a list of qubit objects.
public	deallocateQubit(qubit: BasicQubit) Deallocate a qubit (and sends the deallocation command down the pipeline).
public	isAvailable(cmd: Command): boolean Default implementation of isAvailable: Ask the next engine whether a command is available, i.e., whether it can be executed by the next engine(s).
public	isMetaTagSupported(metaTag: function): boolean Check if there is a compiler engine handling the meta tag
public	receive()
public	send(commandList: Command[]) Forward the list of commands to the next engine in the pipeline.

Receive a list of commands and store them for later inversion.
