Some Mathematical Puzzles that I encountered during my career
Recently, I gave some lectures based on a general-audience personal tour across four (plus one) mathematical puzzles that I encountered during my career. Here is a paper based on these lectures which is meant for a very wide audience (in … Continue reading
The Race to Quantum Technologies and Quantum Computers (Useful Links)
One of my main research directions in the last decade is quantum information theory and quantum computers. (See this post and this one.) It is therefore a pleasure to report and give many links on the massive efforts carried out these … Continue reading
