In this blog post, we’re diving into AWS Quantum Computing with Amazon Braket, a fascinating journey into the world of Quantum Computing.

We’ll start with the basics, explaining what quantum computing is all about. Then, we’ll explore how AWS Quantum Computing works. And finally, we’ll show you how to connect to a quantum computer as an outside user.

Join us as we uncover the mysteries of quantum computing and discover how it’s changing the way we think about computation and problem-solving.

1. Quantum Computing

Quantum computing harnesses the principles of quantum mechanics to process information using qubits, which can exist in multiple states simultaneously. This allows
quantum computers to perform computations at an exponential speed compared to classical computers.

4. Unveiling the Power of Quantum Computing with Amazon Braket

Quantum computing is poised to revolutionize the world of computation, offering unprecedented processing power to tackle complex problems. In this blog, we’ll introduce you to the basics of quantum computing, explore Amazon Braket – AWS’s quantum computing service, and delve into its key components and capabilities.

5. Amazon Braket Overview

Amazon Braket is a fully managed service by AWS that enables developers, researchers, and scientists to experiment with quantum computing.

It provides access to quantum hardware, simulators, and development tools, making it easier for users to explore and build quantum algorithms.

8. Sample Qiskit Quantum Circuit Execution – Python Code

For our reference the basic Qiskit quantum circuit execution – Python code is given below. 

from qiskit import QuantumCircuit, execute, Aer
# Create a Quantum Circuit
qc = QuantumCircuit(2, 2)
# Add a Hadamard gate
# Add a CNOT gate, 1)
# Measure qubits
qc.measure([0, 1], [0, 1])
# Execute the circuit on the simulator
backend = Aer.get_backend('qasm_simulator')
job = execute(qc, backend)
result = job.result()
# Print the result
           Output : {'00': count, '11': count}

The output represents the counts of different measurement outcomes. Since the circuit contains only a Hadamard gate and a CNOT gate, the possible outcomes are {’00’: count, ’11’: count} indicating that both qubits are in the same state (either both in the state |0⟩ or both in the state |1⟩) after the CNOT gate due to the initial superposition created by the Hadamard gate.


Amazon Braket democratizes access to quantum computing, offering a platform for exploration, experimentation, and innovation. With its comprehensive suite of tools and resources, Amazon Braket empowers users to harness the power of quantum computing and drive innovation in their respective fields.
