## 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.
