What is “Quantum Computing?” Most of this blog’s readers are already excited about this technology — after all, we’ve spent many hours reading textbooks and documentation trying to figure out how to write programs for real quantum chips. But many of our friends, family members, and people we randomly encounter still scratch their heads when they hear the words “quantum” and “computer” put together. We think it’s high time that they learn about quantum computing, too.

Partially inspired by Talia Gershon’s awesome WIRED video where she explains quantum computing at five different difficulty…

Quantum computing may be the subject of 40-plus years of research, but many software developers still consider it an obscure technology that “will change the world, one day, in 10 or 20 years.” New quantum computing milestones often feel to those developers like a far cry from actual, large scale applications, or that if it could already be useful, it’s probably something requiring a lot of physics knowledge and experience to do anything with. But such is not quite the case.

One of the best things about Qiskit is the fact that it’s Open Source, enabling anyone to participate in building a future for quantum computing. We wouldn’t be where we are today without the ongoing support of our diverse and interdisciplinary contributors.

Whether you’re a quantum wizard, a Python software developer, or someone who just can’t stop talking about qubits, there are a TON of ways to use your skills to contribute to Qiskit and the growing Qiskit community. …

Today’s qubits are fragile — so fragile that even the act of trying to measure their state can cause unexpected errors. If we hope to use quantum computers to tackle hard computing problems, we’ll need to find ways to correct these pesky errors. Thanks to our recently-published research, there’s a new way to handle these measurement errors — using Qiskit — in a way that takes a reasonable amount of time.

Future fault-tolerant quantum computers will employ error correction, or encoding a single qubit…

On May, 20th at 10:00 am EDT, we’ll be kicking off the next IBM Quantum Challenge to celebrate the history of quantum computing.

This year is a special one — it marks the 40th anniversary of the Physics of Computation Conference, held at MIT’s Endicott House, where some of the era’s foremost thinkers began to seriously consider a computing device based around the mathematical rules of quantum mechanics. It’s also the five-year anniversary of IBM Quantum putting a quantum computer on the Cloud for anyone to use, which directly led to the formation of the global…

It’s difficult to answer “how big a quantum computer can a classical computer simulate,” because the answer is, well, it depends. But built into Qiskit, we have a simulator that can tackle certain kinds of quantum circuits with hundreds of qubits with relative ease.

Quantum circuit simulators are software programs used to mimic the behavior of quantum computers. They aid us in quantum computers’ research and development, and in gaining a better understanding of quantum algorithms. Crucial to using simulators is to pick the one…

This year, we launched the Qiskit Advocates Mentorship Program to provide skill development and professional growth for those interested in the quantum computing industry. Today, we are excited to share some of the projects that Qiskit Advocates have been working on.

Qiskit Advocates are members of an exclusive, global program that supports some of the Qiskit community’s most active contributors from over 30 countries. Advocates get special access to Qiskit core members, take on projects to improve the Qiskit community, and gain recognition from IBM. …

Hello world, I’m Rodney Osodo. An undergrad student at Jomo Kenyatta University of Agriculture and Technology in Kenya. I’ve been interested in quantum computing for a while now and am so excited to share my learning from my most recent experience with quantum computing.

For my Quantum Open Source Foundation project, I built a quantum variational classifier using a heart attack dataset. The purpose of this project was to help me gain insight into the actual construction of a quantum model, applied to real data. …

Natural Sciences and Quantum Simulation

Richard Feynman envisioned quantum devices as a new computational paradigm for the simulation of Nature at its fundamental (quantum) level. Today, we are announcing Qiskit Nature, a unique platform to bridge the gap between natural sciences and quantum simulations. The modularity of Qiskit Nature will allow researchers in different areas of natural sciences (including physics, chemistry, material science and biology) to model and solve domain-specific problems using quantum simulations as well as direct experiments on quantum computers via the IBM Quantum Cloud systems. …
