The different pathways to a fault-tolerant machine

Finding the prime factors of a 2048-bit number would take a classical computer millions of years, but a quantum computer could do it in just minutes. That is because a quantum computer is built on qubits, which take advantage of quantum superposition to reduce the number of steps required to complete the computation. But how do you actually make a qubit in practice and how do you read and write information on it?

Not all qubits are born equal. In an exciting quest to reach the Holy Grail of a fault-tolerant system, a ton of research is being done in…

The importance of the bassist

Every Saturday night I sit in front of my screen with a board of cheese, a glass of red and my best headphones, to virtually tune into the various venues that are streaming live jazz these days. Smalls & Mezzrow, Smoke Jazz and Supper Club, Parker Jazz Club… are offering live performances over the Internet, accepting donations from listeners as a means to pay royalties to their musicians and try to keep their business open while things get back to normal.

Jazz is one of those acquired tastes that has grown on me over the years. Living in Austin I…

A Tribute to John Coltrane

In 1922, German author Herman Hesse gave life to Siddhartha, an ascetic who spends his life seeking the meaning of existence. After a lifetime of mediation, many disappointments and hard lessons, he ends up settling in an old riverbank, where he discovers the multiple wisdom voices that the stream brings, to eventually reach a wordless communion with Nature and its simplicity. Regardless the parallelisms with Buddhism and leaving religious considerations aside, I like the idea of embracing the change and using every mistake we make in life as a stepping stone to grow up to the next level.

Deconstructing my journey to the East

One of my early culture shock recollections dates from a visit to Singapore in the Spring of 2005. I had been shipped by a former employer to work with one of our customers in the region. Being my first time in Asia, I spent most of my spare time exploring the unique vibe of this incredible city.

Singapore is a melting pot of cultures and a hub between Eastern and Western lifestyles. With three quarters of the population being ethnic Chinese, before long I found myself chatting with locals squatting in line while waiting for the bus, business owners cheerfully…

Here you are once again staring at your phone’s calendar as another year is coming to an end. All the good deeds that you planned for the preceding 12 months seem now a distant blur. Once again life implacably got on the way of your new year’s resolutions, and for the past few months you have started to fantasize about when your next attempt will be. As you casually scroll up and down through your meetings, you are getting ready to start over the vicious circle of good intentions.

Your rational self understands that only a very low percentage of…

As a student of foreign languages, I have been interested for some time in the mechanisms that our brain uses to acquire new vocabulary, consolidate grammar, develop a particular accent, and how step by step we read, write, listen and speak our way to fluency. When it comes to second language acquisition, science knows the parts of the brain involved in the learning process, what works well and what doesn’t.

One of the things that work is a learning technique called “interleaved practice”. Let’s consider two forms of learning: In one form you massively try to learn a particular skill…
