On topological quantum computers

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 contexts of cryptography and complexity. Yet, we haven’t talk much about practicalities. The outstanding problem with entangled superpositions of spinning electrons, polarized photons or most[…]

On quantum computing and cryptography

Cryptography is the cornerstone of secure communication. Broadly speaking, cryptography deals with creating and studying protocols that prevent third parties (public or adversaries) from reading messages. It is strongly tied to information security topics such as confidentiality, data integrity, identification, authentication or non-repudiation / proof. Today’s cryptography is heavily based on mathematics: cryptographic algorithms are[…]

Having fun with Bell states and Q#

In a previous post, we introduced the basic concepts of quantum computing, during which quantum entanglement, Bell states and usual quantum gates such as Hadamard’s or Pauli’s were quickly addressed. Today, we’re going to explore some of these concepts and start having fun with quantum programming to illustrate these ideas. Quantum entanglement Quantum entanglement is a[…]

On quantum computing

Quantum computing as made the headlines recently. At IBM’s inaugural Index Developer Conference held in San Francisco, the company showed off its latest prototype: a quantum computing rig housing 50 qubits, one of the most advanced machines currently in existence. Google Quantum AI Lab announced Bristlecone, its new quantum processor, at the annual American Physical[…]

E.V.E is all ears

Now that enough progress has been made on E.V.E touch-enabled interface, and since we added a websocket-enabled general purpose middleware (A.D.A.M) to handle local hardware and proxy HTTP requests, we can now tackle voice recognition. The audio sub-system The audio sub-system is probably the weakest point of Raspberry Pi. Without extension (such an USB audio sub-system), only two audio[…]

Project “Jarvis”: step three (the brain)

During the last steps, voice recording, speech-to-text and text-to-speech feasibility was studied. Now enters another difficicult part: the brain ! The last steps implied the use of external services for voice-recognition and text-to-speech capabilities. When it comes to Jarvis’ brain, the idea is twofold: Onboard answer engine: part of the analysis will be done onboard[…]

Project “Jarvis”: step two (speak to me)

In my previous post, I conducted a few experiments with speech recognition via Google’s Speech API and get enough results to push the project “Jarvis” a bit further. Now it is time for Jarvis to speak !   Text-To-Speech engines There are many “Text-To-Speech” engines already packaged for the Rasberry Pi. Namely: espeak: eSpeak is[…]

Upgrading quantum-bits

Once again, it’s been a long time since the last post. Partly because I’m overworked, partly because my good old blog became technically obsolete and is now plagued by security vulnerabilities. Some *ucking morons have been exploiting these holes in order to send spam, which pissed me off quite a bit (and almost got me[…]

Bad luck :(

After years of loyal service, my home server HDD is given evident signs of aging, which include some data loss. And guess what ? Yes, both redundant hard disks on which I’m backuping this server are also giving signs of failure… Now, that’s what I call bad luck 🙁 I’m crossing my fingers while trying[…]
