Some useful algorithms for qiskit

Data Cybernetics qiskit-algorithms

qiskit is an open-source compilation framework capable of targeting various types of hardware and a high-performance quantum computer simulator with emulation capabilities, and various compiler plug-ins.

This library sports some useful algorithms for quantum computers using qiskit as a basis.

Features

• Multi Qubit Quantum Fourier Transform
• Draper adder
• Uniform Rotations
• State Preparation

Installation

This library requires Python version 3.5 and above, as well as qiskit. Installation of this plugin, as well as all dependencies, can be done using pip:

$ python -m pip install dc_qiskit_algorithms

To test that the algorithms are working correctly you can run

$ make test

Getting started

You can use the state preparation as follows

from dc_qiskit_algorithms.MottonenStatePrep import state_prep_möttönen

vector = [-0.1, 0.2, -0.3, 0.4, -0.5, 0.6, -0.7, 0.8]
vector = numpy.asarray(vector)
vector = (1 / numpy.linalg.norm(vector)) * vector

qubits = int(numpy.log2(len(vector)))
reg = QuantumRegister(qubits, "reg")
c = ClassicalRegister(qubits, "c")
qc = QuantumCircuit(reg, c, name='state prep')
state_prep_möttönen(qc, vector, reg)

After this, the quantum circuit is prepared in the given state. All complex vectors are possible!

Please refer to the documentation of the dc qiskit algorithm Plugin .
