The most common contracts traded in the financial markets are perpetual swaps and future contracts and option contracts. These are derivatives based on an underlying asset, such as stocks, commodities, currencies, or cryptocurrencies.

For the sake of exploring the theoretical limits of quantum computing, let us take an optimistic perspective—setting aside current hardware challenges such as qubit coherence, gate fidelity, error correction, and the lack of scalable, high-quality quantum systems. If we assume, for argument’s sake, that these limitations are fully resolved and that practical quantum computers can operate with perfect stability and unlimited scalability, we can focus on what quantum algorithms are able to achieve in principle, regardless of present-day engineering constraints.

My familiarity with markup languages ​​is almost nil. I thought that by creating the blog with Jekyll I could completely get rid of the need to write html, and it would just copy a template. Well, I found out that it is not so. The template I chose had no justified alignment. Thought I could put some kind of markup in markdown to solve this. I was wrong again. So something will always be needed to know about html. In that case, reading and editing html are necessary at least.

I have changed from KDE Neon to Manjaro KDE Plasma in the middle of the last week. I had no problems by installing Wolfram Mathematica 11.3, however this one did not open properly. So I decided open it by terminal and found a couple of errors in sequence. All of them are reported in the Mathematica post from the Archlinux Wiki. The last error solution is my contribution to community.
