InnerProduct
(num_qubits)[소스]¶ 기반 클래스:
qiskit.circuit.quantumcircuit.QuantumCircuit
A 2nqubit Boolean function that computes the inner product of two nqubit vectors over \(F_2\).
This implementation is a phase oracle which computes the following transform.
\[\mathcal{IP}_{2n} : F_2^{2n} \rightarrow {1, 1} \mathcal{IP}_{2n}(x_1, \cdots, x_n, y_1, \cdots, y_n) = (1)^{x.y}\]The corresponding unitary is a diagonal, which induces a 1 phase on any inputs where the inner product of the top and bottom registers is 1. Otherwise it keeps the input intact.

Attributes

ancillas
¶ Returns a list of ancilla bits in the order that the registers were added.

calibrations
¶ Return calibration dictionary.
 The custom pulse definition of a given gate is of the form
{‘gate_name’: {(qubits, params): schedule}}

clbits
¶ Returns a list of classical bits in the order that the registers were added.

data
¶ Return the circuit data (instructions and context).
 반환값
a listlike object containing the tuples for the circuit’s data.
Each tuple is in the format
(instruction, qargs, cargs)
, where instruction is an Instruction (or subclass) object, qargs is a list of Qubit objects, and cargs is a list of Clbit objects. 반환 형식

extension_lib
= 'include "qelib1.inc";'¶

global_phase
¶ Return the global phase of the circuit in radians.

header
= 'OPENQASM 2.0;'¶

instances
= 16¶

metadata
¶ The user provided metadata associated with the circuit
The metadata for the circuit is a user provided
dict
of metadata for the circuit. It will not be used to influence the execution or operation of the circuit, but it is expected to be passed between all transforms of the circuit (ie transpilation) and that providers will associate any circuit metadata with the results it returns from execution of that circuit.

num_ancillas
¶ Return the number of ancilla qubits.

num_clbits
¶ Return number of classical bits.

num_parameters
¶ Convenience function to get the number of parameter objects in the circuit.

num_qubits
¶ Return number of qubits.

parameters
¶ Convenience function to get the parameters defined in the parameter table.

prefix
= 'circuit'¶

qubits
¶ Returns a list of quantum bits in the order that the registers were added.
