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.

Write once and execute on any supported quantum providers using one syntax

from quantumcat.utils import providers  
num_of_qubits = 2
qc = QCircuit(num_of_qubits)
qc.h_gate(0)
qc.cx_gate(0, 1)

# Execute on Google Cirq
result = qc.execute(provider=providers.GOOGLE_PROVIDER, repetitions=1024) 

# Execute on IBM Qiskit
result = qc.execute(provider=providers.IBM_PROVIDER, repetitions=1024)

# Execute on Amazon Braket
result = qc.execute(provider=providers.AMAZON_PROVIDER, repetitions=1024)

# Execute on All providers in one go
circuit.compare_results(plot=True)

Execute on real IBM device using quantumcat

from quantumcat.utils import providers  
  
result = qc.execute(provider=providers.IBM_PROVIDER,
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/  

Installation

pip install quantumcat

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  

Draw Circuit

from quantumcat.utils import providers  
  
qc.draw_circuit(provider=providers.GOOGLE_PROVIDER)

High-Level Functions

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  

High-Level 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)
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  

Visualization

Histogram

circuit = QCircuit(1)
circuit.superposition(0)
counts = circuit.execute(provider=providers.GOOGLE_PROVIDER, repetitions=1024)
circuit.histogram(counts) 

circuit = QCircuit(1)
circuit.superposition(0)
state = circuit.execute(provider=providers.GOOGLE_PROVIDER, simulator_name=constants.STATEVECTOR_SIMULATOR)
circuit.bloch_multivector(state) 

circuit = QCircuit(1)
circuit.superposition(0)
state = circuit.execute(provider=providers.GOOGLE_PROVIDER, simulator_name=constants.STATEVECTOR_SIMULATOR)
circuit.state_qsphere(state)
