- [From Shor to the Quantum Hidden Subgroup Problem – A jumpstart](https://www.quantum-computing-info.com/quantum-hidden-subgroup-problem/) - A gentle and intuitive introduction and a broad overview to the very fascinating and elegant subject of the "Hidden Subgroup Problem".
- [Quantum Chemistry in a Nutshell I – For Quantum Computing Enthusiasts](https://www.quantum-computing-info.com/quantum-chemistry-in-a-nutshell/) - These articles are a condensed but still pretty detailed introduction to many concepts and methods of quantum chemistry that are relevant for quantum computing.
- [What is the deal with Cat-Qubits?](https://www.quantum-computing-info.com/cat-qubits/) - A quick-guide on the fundamental concepts of cat qubits and related publications. It outlines the current state of the new approach and its key players.
- [Quantum Chemistry in a Nutshell II – Post-Hartree-Fock methods](https://www.quantum-computing-info.com/post-hartree-fock/) - Quantum chemistry is one of the top most promising and one of the first applications for quantum computing. Most likely, the success in quantum chemistry will serve as a reliable “early-alerting indicator” for other potential applications. Thus, staying up to date to the developments in chemistry is important for the entire quantum computing community! Part
- [My Cover-Article in the iX-Magazine 06/2024 about NISQ](https://www.quantum-computing-info.com/cover-article-in-ix-magazine-nisq/) - I am delighted that the well-known German iX-magazine about professional computing has published my new article: As a 7-page cover-story about NISQ in the current June-issue. The iX-magazine and Quantum Computing I think, it is fair to say that the iX-magazine is the major magazine about professional computing in Germany. Because of my popular German
- [Welcome to my blog!](https://www.quantum-computing-info.com/welcome-note/) - First of all: A warm welcome to everybody who visits my new website. Before I start posting, I thought it would be appropriate to introduce myself and share a few words about the intention of this blog and what kind of topics you will find in here. I am a senior consultant for professional computing
- [Is Google's quantum supremacy milestone now really obsolete?](https://www.quantum-computing-info.com/is-googles-quantum-supremacy-obsolete/) - In August 2022 news has spread through the media, that a team of researchers from the Chinese Academy of Sciences managed to implement Google‘s quantum supremacy task on a classical supercomputer. Regarding the fact that Google's 2019-milestone plays a prominent role for the quantum computing community and also for the communication with the public, I
- [How to visualize quantum entanglement?](https://www.quantum-computing-info.com/visualizing-quantum-entanglement/) - In case you want to explain some central aspects of quantum information theory to curious people (like to explain aspects of the recent Nobel Prize in physics), some visualizations in my free online book might help you out. In 2018 I launched my "free online online book for curious people" www.quantencomputer-info.de . I think, one
- [Challenging the “Exponential Quantum Advantage Hypothesis“ for Quantum Chemistry](https://www.quantum-computing-info.com/exponential-quantum-advantage-chemistry/) - Ever since Feynman‘s statement “Nature isn‘t classical dammit“ there exists the general agreement in the quantum computing community that fault tolerant quantum computers will generically provide an exponential quantum advantage in quantum chemistry for problems of practical interest. A well-known quantum chemist from Caltech now challenges this "Exponential Quantum Advantage Hypothesis“ for a most important
- [Does Quadratic Quantum Speedup have a problem?](https://www.quantum-computing-info.com/quadratic-quantum-speedup-problem/) - As quantum computing evolves the community focuses on the next steps towards fault tolerance. Recent estimates for the overhead of error correcting codes on reasonable hardware assumptions conclude certain unfavorable results for quadratic quantum speedups. As this might effect important use cases for quantum computing we should take a closer look at these results. Image
- [The State of Quantum RAM: A new enlightening Investigation](https://www.quantum-computing-info.com/state-of-quantum-ram-qram/) - A highly interesting, recent preprint brings light into the dark: A thorough investigation about the state of quantum RAM / QRAM and its fundamental challenges.
