By Jay Shah The Bloch sphere is one of the most popular and recognizable tools for helping new learners understand quantum computing fundamentals. Now, there’s a Qiskit Ecosystem project that helps users visualize Bloch spheres with just a few clicks on a convenient GUI-based tool. The Quantum-Glasses package is a…

By Abby Mitchell, Luciano Bello, Matthew Treinish, Jake Lishman We’re excited to announce the release of Qiskit v0.45! Read on for a summary of the key highlights and, as always, you can find the full release notes in our documentation here. With this being the last release before Qiskit 1.0…

By Zhiding Liang, Jinglei Cheng, and Hanrui Wang The world of quantum computing is always evolving. Researchers and scientists are constantly pushing the boundaries, looking for ways to improve the methods they use to harness the power of quantum mechanics. Variational quantum algorithms (VQAs), for example, have gained significant traction…

Can a cat be dead and alive at the same time? In 1935, quantum physicist Erwin Schrödinger came up with a thought experiment showing that, according to quantum mechanics, a cat can exist in a superposition of being alive and dead. Schrödinger’s aim was to demonstrate the absurdity of quantum…

Today, we’re announcing important changes to Qiskit.org that you should be aware of. Starting on November 29, 2023, Qiskit Documentation and Qiskit educational resources will live on IBM Quantum Platform and will be removed from Qiskit.org. We will be slowly moving content over until then. Qiskit is, first and foremost…

By Robert Davis, Julien Gacon, Abby Mitchell, and Luciano Bello When it comes to quantum circuits, sometimes the “do it yourself” approach is best. Even for common subroutines like the quantum Fourier transform (QFT), a user may find that it’s better to build their circuit by hand, so they can…

By Daniella Garcia Almeida Some researchers believe quantum computers could one day play a vital role in the fight against climate change, enabling simulations of novel sustainable materials, or solving complex optimization problems to minimize greenhouse gas emissions. But when will quantum computers become mature enough to actually tackle these…

By Alex Lukin, Technical Writer, IBM Quantum and Qiskit Quantum researchers and learners tend to spend their time focused on what quantum computers can do, both the noisy quantum computers we have today and the much more powerful ones we hope to have in the future. But we’ve recently seen…

By Daniella Garcia Almeida It was during her physics PhD that Helena Zhang first realized the untapped potential of cloud-based quantum computing. But it was her discovery of Qiskit that helped unleash that potential. Zhang is the technical lead for Qiskit Experiments. Qiskit users have struggled recreating experiments, since research…
