Qiskit is an open-source SDK for quantum computing developed by IBM.

The project simplifies certain elements of coding quantum computing applications. Specifically, this SDK allows users to program on quantum computers directly from their programming device.

Which, theoretically, allows anyone to build quantum circuits, run quantum algorithms and study various quantum phenomena.

Qiskit has over 6,000 stars on GitHub.

## Qiskit and Quantum Computing’s Commercialization

Qiskit is part of the Quantum Computing Goes Commercial trend.

Although not a practical technology yet, a growing number of companies are working to commercialize quantum computers.

For example, Google has estimated that they will deliver a commercial quantum computer by 2029.

Visa, Goldman Sachs, and Volkswagen have also started looking for ways to incorporate quantum computing into their operations.

According to Gartner, 40% of medium-to-large organizations will implement quantum computing initiatives by 2025.

This is why Honeywell forecasts that the commercialization of quantum computing will create a $1 trillion industry over the next decade.

## Qiskit – FAQs

### What is a Qiskit Circuit?

A Qiskit circuit is a directed graph where the nodes represent quantum operations and the edges represent the order in which those operations are applied.

### What is a Quantum Circuit?

A quantum circuit is a sequence of quantum gates, and these circuits are referred to as “an n-qubit register” if they contain n qubits.

### What is an Open Source Software Development Kit (SDK)?

An open-source software development kit (SDK) is a set of tools that allows developers to create software applications.

An SDK typically includes a compiler, debugger, and other tools needed to create and test software applications.

Qiskit is an example of an open-source SDK.

### What is Quantum Computing?

Quantum computing is the use of quantum-mechanical phenomena, such as superposition and entanglement, to perform operations on data.

A quantum computer operates on qubits, which are units of quantum information.

Qubits can represent a zero, a one, or both values simultaneously.

This allows quantum computers to perform several calculations at once.
