IBM Quantum Experience, also known as IBM Q Experience, is a pioneering cloud-based platform that provides access to IBM's quantum processors. Launched in 2016, it allows researchers, educators, and enthusiasts to run quantum algorithms and experiments on real quantum hardware via the cloud. This initiative is part of IBM's broader effort to advance quantum computing and make it accessible to a wider audience.

History

IBM Quantum Experience was introduced on May 4, 2016, marking a significant milestone in the field of quantum computing. The platform initially offered access to a 5-qubit quantum processor, which was a breakthrough in making quantum computing resources available to the public. Over the years, IBM has expanded the capabilities of the platform, adding more powerful quantum processors and enhancing the user interface and tools available for quantum programming.

Quantum Processors

IBM Quantum Experience provides access to a variety of quantum processors, each with different numbers of qubits and capabilities. The processors are based on superconducting qubit technology, which is one of the leading approaches in the development of quantum computers. Superconducting qubits operate at extremely low temperatures, typically around 15 millikelvin, to minimize thermal noise and maintain quantum coherence.

5-Qubit Processor

The initial 5-qubit processor offered by IBM Quantum Experience was a significant step forward in quantum computing. It allowed users to run simple quantum algorithms and gain hands-on experience with quantum programming. The processor featured a basic architecture that enabled the execution of fundamental quantum gates and measurements.

16-Qubit Processor

Following the success of the 5-qubit processor, IBM introduced a 16-qubit processor, which provided more computational power and complexity. This processor allowed for the execution of more advanced quantum algorithms and experiments, enabling researchers to explore new areas of quantum computing.

20-Qubit and Beyond

IBM continued to push the boundaries of quantum computing by introducing 20-qubit processors and later, even more powerful systems. These processors offer increased qubit connectivity and coherence times, which are critical for running more complex quantum algorithms and achieving higher levels of quantum error correction.

Quantum Programming

IBM Quantum Experience provides a comprehensive set of tools and resources for quantum programming. Users can write and execute quantum algorithms using the Qiskit framework, an open-source quantum computing software development kit (SDK) developed by IBM.

Qiskit Framework

Qiskit is a modular and extensible framework that allows users to create, simulate, and run quantum circuits on IBM's quantum processors. It consists of several components, including:

• **Qiskit Terra**: The foundation of Qiskit, which provides the tools for creating and manipulating quantum circuits and running them on quantum hardware.
• **Qiskit Aer**: A high-performance simulator for testing and debugging quantum circuits before running them on actual quantum hardware.
• **Qiskit Ignis**: A library for quantum error correction and mitigation, which helps improve the accuracy of quantum computations.
• **Qiskit Aqua**: A library for quantum algorithms, including applications in chemistry, optimization, and machine learning.

Quantum Circuits

Quantum circuits are the fundamental building blocks of quantum algorithms. They consist of a sequence of quantum gates applied to qubits, which manipulate their quantum states. IBM Quantum Experience allows users to design and visualize quantum circuits using a graphical interface or by writing code in Python.
