Quantum Bits: Recent Episodes
None
In the previous post, I finally took the time to announce the creation of the Quantum-Bits Youtube Channel: https://www.youtube.com/@quantum-bits-org. The first videos, published almost a year ago, were dedicated to ...
I haven’t posted for quite some time. Actually … over a year. It’s been challenging and very difficult times, where I had to take care of the health of both ...
France is a strange country. We tend to argue about anything. Nonsensical – yet tenacious – “troll wars” have been raging for years, for the naming of delicious viennoiseries or ...
In a previous post, I presented the restoration of an Apple IIc that I acquired a couple of months ago. Since it was my first steps with an Apple II ...
It’s been over 5 months since my last vintage computer acquisition. In the meantime, I had a lot of fun with RecalBox 9, emulating tons of oldies. But now, we ...
It’s been a couple of months since my last vintage computer acquisition. I have been hunting for a DDI-1 external disk drive and a Vortex internal expansion RAM card for ...
Last year, right on time for MARCHintosh 2022, I acquired my very first classic Macintosh, that I have been enjoying ever since. But the vintage-computing fever troubled my mind, pushing ...
At the end on the previous post (on the Matra-Hachette Alice 90) I was left with an open question: which vintage computer shall I work on next ? I had ...
After the short LEGO break from last post, let’s go back to vintage computers. I had explored a few 16-bit computers (Atari ST and Mac Plus), so I decided to ...
Let’s take a (short) break from quantum-computing and retro-computing. LEGO sets have been an important part of my childhood. I believe I started having fun with LEGO bricks while I ...
After months of hard work restoring a Macintosh Plus, this time, I sailed towards more familiar shores: the Atari 1040STF. I owned an Atari 1040STF back in the late 80’s ...
I am an Apple Fanboy. Always been. Nevertheless, it took me a long time to actually own an Apple device. The first Mac I ever bought was a 12″ PowerBook ...
Let’s go a little further into retro-computing. After these first steps with the Sinclair ZX81 and ZX Spectrum, if was time for another British 8bit computer from the 80’s: the ...
Let’s take a (short) break from vintage computers. As a consequence to the COVID-19 pandemics and lock-downs, home-office turned from an occasional to a day-to-day way of working. We had ...
After my first baby steps into the retro-computing world with a ZX81, I thought I should add a new member to the family. In memory of the late Lord Sinclair, ...
My Previous posts on reto-computing were dealing with emulating old 8-bit and 16-bit computers and consoles. That’s is what indeed triggered a bit of retro-gaming and retro-computing addiction. And, of ...
In the last post, I explained how I jumped into the retro-computing bandwagon, and built a few DIY boxes for retro-gaming via software emulation, based on the RecalBox project. During ...
The COVID-19 pandemic had (and, unfortunately still has) a strong impact on us all. We all tried our best to cope with it, our own ways. Somehow, lock-downs triggered a ...
This question stems from discussions at work about the notion of “data gravity”, which, 10 years after its inception, seems to make a comeback and draw some kind of vague ...
Voici le rapport technique d’évaluation des technologies d’informatique quantique élaboré par l’équipe du Digital Labs d’Econocom. Notre objectif est d’évaluer expérimentalement les technologies quantiques actuelles, avec pour application la résolution ...
Alice and Bob are fictional characters often used to describe cryptographic protocols. We introduced them in a previous article on quantum cryptography. Picture a situation where Alice and Bob are ...
Cloud-based quantum computing is the invocation of quantum emulators, simulators or processors through the cloud. Increasingly, cloud services are being looked on as the method for providing access to quantum ...
The worldwide quest to build practical quantum computers is undergoing a critical period. Fault-tolerant quantum computers will soon provide significant computational speedups for problems like factoring, search, or linear algebra, ...
Mixing quantum computing and Artificial Intelligence (AI) may sound like a new buzzword. However, since quantum computing advances are hinting at profound changes in the very notions of computation, it ...
In a series of posts, we introduced various quantum computing concepts: How information and quantum mechanics are related ? What is quantum computing ? What are Bell states ? What ...
We have been talking about quantum computing for a few weeks now. We have talked about its theoretical principles (quantum entanglement, no-cloning theorem, …) and its applications, especially in the ...
