Aug 5, 2024 · Quantum computing is a rapidly-emerging technology that harnesses the laws of quantum mechanics to solve problems too complex for classical computers.

Aug 23, 2023 · An easy-to-follow, popular-science-style guide covering the basics of quantum computing (similar in scope to this article but in much more detail). Also covers related fields such as quantum cryptography.

May 9, 2023 · Have you ever heard of a computer that can do things regular computers can’t? These special computers are called quantum computers. They are different from the computer you use at home or school because they use something called “qubits” instead of regular “bits”. A bit is like a light switch that can only be on or off, like a zero or a one.

Learn the basics of quantum computing, and how to use IBM Quantum services and systems to solve real-world problems. Learn potential use cases and best practices for experimenting with quantum processors having 100+ qubits. Learn mathematical aspects of quantum computing at the advanced undergraduate or introductory graduate level.

Oct 23, 2024 · A quantum computer is a computer that takes advantage of quantum mechanical phenomena. Quantum computers use quantum states of matter to store and compute information. They can "program" quantum phenomena to do things faster or better than classical computers.

Mar 18, 2025 · Quantum computers also have input, output, information processing and memory. But instead of regular classical bits, quantum computers use quantum bits, or qubits. Like Schrödinger’s unfortunate cat, qubits can be put into superpositions of multiple states. In other words, a qubit can be in state 0, state 1, or a mix of the two.

Mar 18, 2024 · In this tutorial, we covered the basic principles of quantum computing built on top of quantum mechanics. This included the core principles of quantum mechanics, like superposition and entanglement, and the basic elements of quantum computing, like qubits.

Jul 3, 2022 · The new guide explains the basics of quantum computing and quantum programming, including quantum algorithms.

Quantum computing is a branch of physics and computer science that provides a new method of computation with the help of quantum physics, for example, entanglement, superposition, interference, and decoherence. They solve difficult problems effectively and easily when compared to any supercomputer.

A quantum computer is a device performing quantum computations. It manipulates the quantum states of qubits in a controlled way to perform algorithms. A universal quantum computer is defined as a machine that is able to adopt an arbitrary …
