Author : Phd. Jonas Araujo, Researcher at ColibrITD In my previous article, I wrote that two-level systems are the main resource for quantum computing. They provide quantum bits, or qubits, whose states can be superposed and entangled in quantum algorithms,...

Contextuality in quantum computing
Author : Phd. Henri de Boutray, Researcher at ColibrITD Quantum Mechanics is known as a counter intuitive field, where things seen as impossible in our day-to-day life are perfectly normal. The two examples commonly given when mentioning this counter intuitive aspect...
To reject or not to reject, that is the question
Author : Phd. Nadia Milazzo, Researcher at ColibrITD The story of a decision problem for quantum systems While quantum technologies progress and advance rapidly, many questions arise around their properties, functioning and potential. According to the European Quantum...
Interpretations of quantum mechanics
Author : Phd. Marta Reina, Researcher at ColibrITD The diatribe between realists and orthodox before Bell’s theorem In quantum mechanics, the state of a particle can be determined through Schrödinger’s Equation, representing an analogous to the well-known...
Quantum Games: when the players enjoy entanglement
Author : Phd. Hamza Jaffali, Researcher at ColibrITD Game Theory is a quite recent field of science, recognized as an important tool in many disciplines, coming with various applications, from biology to economics, as well as in engineering and mathematics [I1, I2]....
Can we really deal with bit flip ?
Author : Phd. Marta Reina, Researcher at ColibrITD From a merely theoretical point of view, there is no doubt that quantum computers would have extraordinary power, but — concretely — we have to face the truth and fight against the existence of noise and errors. The...
(I Can’t Get No) SATisfaction
Author : Phd. Henri de Boutray, Researcher at ColibrITD Solving problems with SAT Travel paths can be optimized using SAT solvers. credit Delta Problem-solving is a cornerstone of our society as it allows us to create complex processes that make our lives easier....
Getting to know Quantum Fourier Transform
Author : Phd. Hamza Jaffali, Researcher at ColibrITD Joseph Fourier (1768 –1830) is a french mathematician and physicist. He is known for having determined, by calculus, the heat diffusion by using the decomposition of an arbitrary function thanks to his famous...
Quantum Entanglement: how to classify it?
Author : Phd. Hamza Jaffali, Researcher at ColibrITD What is Quantum Entanglement? Quantum Entanglement … what a mysterious phenomenon. It happens at the subatomic scale and has no equivalent in the macroscopic world. It has historically been questioned and formalized...
Quantum Machine Learning: A quick overview
Author : Phd. Hamza Jaffali, Researcher at ColibrITD Introduction The goal of Machine Learning is to teach the machine how to perform a specific task, without providing explicit instructions. It is divided in three main families: supervised learning (teaching by...
