Introduction

A cross-platform open-source high-level quantum computing library so that the quantum community could concentrate on building quantum applications without much effort.

Purpose

quantumcat is a cross-platform library and is built on the principle of write once and execute any quantum provider. The purpose of this library is to help developers create cross-platform quantum applications in few lines of code.

Problems with current QC Libraries

• Platform dependent code: To execute code on platforms such as IBM, Google, and so on, Developers need to write code separately for each platform independently putting lots of efforts.
• Basic Knowledge of quantum gates and circuits required: Presently, It is very tough to create quantum applications given the fact that many available libraries are low-level libraries i.e. developers have to understand low-level concepts such as gates and circuits before they can actually start working on quantum applications. This is not natural to many developers who are accustomed to high-level concepts rather than worrying about gates and circuits.

Examples

Circuit Creation

from quantumcat.circuit import QCircuit

num_of_qubits = 3
qc = QCircuit(num_of_qubits)

Single-Qubit Gate

qc.x_gate(0) 
# applies X gate on qubit 0

Two-Qubit Gate

qc.cx_gate(0, 1) 
# control qubit, target qubit

Multi-Qubit Gate

qc.mct_gate([0, 1], 2) 
# control qubits array, target qubit

Superposition

qc.superposition(0) 
# puts qubit 0 in superposition

Entanglement

qc.entangle(0, 1) 
# entangles qubit 0 with qubit 1

Phase Kickback

qc.phase_kickback(0) 
# applies |-> to qubit 0

Draw Circuit

from quantumcat.utils import providers

qc.draw_circuit(provider=providers.GOOGLE_PROVIDER) 
# OR providers.IBM_PROVIDER / providers.AMAZON_PROVIDER 

Execute on Simulators

from quantumcat.utils import providers

results = qc.execute(provider=providers.GOOGLE_PROVIDER, repetitions=1024) 
# OR providers.IBM_PROVIDER / providers.AMAZON_PROVIDER

Execute on real IBM device

from quantumcat.utils import providers

results = qc.execute(provider=providers.IBM_PROVIDER, repetitions=1024, 
api='API KEY from IBM Quantum dashboard', device='IBM DEVICE NAME such as ibmq_manila or ibmq_quito')
# Copy API and Device name from https://quantum-computing.ibm.com/

Applications

Random Number Generator

from quantumcat.utils import providers, constants
from quantumcat.applications.generator import RandomNumber

random_number = RandomNumber(length=2, output_type=constants.DECIMAL)\
        .execute(provider=providers.GOOGLE_PROVIDER)
# OR providers.IBM_PROVIDER / providers.AMAZON_PROVIDER
print(random_number)

# To generate random number on actual IBM device
random_number = RandomNumber(length=2, output_type=constants.DECIMAL)\
        .execute(provider=providers.IBM_PROVIDER, repetitions=1024, 
api='API KEY from IBM Quantum dashboard', device='IBM DEVICE NAME such as ibmq_manila or ibmq_quito')
print(random_number)

Password Generator

from quantumcat.applications.generator import Password

password = Password(8).generate()
print(password)
# Length should be between 5 - 20
# Password is generated in hexadecimal format using QRNG@ANU JSON API

OTP Generator

from quantumcat.applications.generator import OTP

otp = OTP().generate()
print(otp)
# 5 digits OTP is generated using QRNG@ANU JSON API
