Daniel Manzano holds a PhD in Physics (Universidad de Granada). After a postdoc at the Institute for Quantum Optics and Quantum Information (Innsbruck) of the Austrian Academy of Sciences, he worked also as a postdoc at the Chemistry department of the Massachusetts Institute of Technology (Cambridge). He is now Talent Hub researcher at the University of Granada.
Entanglement is the purest and most important quantum property. Unlike classical systems, quantum objects can be connected independently of their distance and if we perform a measurement in one part the other one is affected instantaneously. Intuitively, this can be considered a violation of relativity because this theory states that no information can travel faster […]
The question of the arrow of time has been on the table for centuries. The microscopic laws that determine the behaviour of matter (both in the classical and quantum regimes) are reversible. By seeing a video of a billiard board, with just a few balls, you will not be able to determine if the video […]
Two of the hot topics in science an technology nowadays are related to Computer Science. They are Artificial Intelligence (AI) and Quantum Computing (QC). AI is a really old field, as humanity has dreamed of having autonomous machines for decades. Quantum Computing is not as old as AI. It is considered that the idea of […]
Particle physics is an interesting and complicated field of study. Its theoretical framework, the Standard Model, was developed during the second half of the twentieth century and it opened he possibility to explaining the behavior of the basic blocks of the Universe. It also classified all the particles, from the electron (discovered in 1897) to […]
Unfortunately, this interesting story is coming to an end. In the previous post we already disscussed the first loophole-free Bell experiment, but if this experiment was conclusive the story is closed. Why are we still discussing it? It happens sometimes in History that people look to solve a problem for decades and suddenly two different […]
In previous posts, we have reviewed the different loopholes of Bell experiments. To make a long story short, entanglement experiments are based on measuring some magnitudes in two quantum systems, calculating a value based on the outcomes of these measurements, and if this value goes beyond a certain threshold we can say that the universe […]
In previous posts, we have discussed the two main loopholes of Bell experiments, the locality loophole, and the detection loophole. Both were closed a long time ago, but only recently they were closed in the same experiment. Let us summarize the kind of experiments we are dealing with by an example. Alice and Bob will […]
Let ‘s continue with the story of the development of the loophole-free Bell experiment. As we discussed in the first post, it is possible to prove that the universe is either non-real, meaning that the outcomes of some experiments can only be predicted statistically, or it is non-local, meaning that there are signals that propagate […]
In our previous post, we have discussed the importance of a loophole-free entanglement experiment. Now, we are going to discuss one of the most important loopholes for this kind of experiments, the locality (or communication) loophole . To understand the locality loophole we need to review the Bell’s inequalities experiments one more time. Alice and […]
Recently, a new experiment has attracted a lot of attention. It was published in Nature and entitled as “Loophole-free Bell inequality violation using electron spins separated by 1.3 kilometres ” . Many scientific and non-scientific media took account of the results of the experiment and published short news with fancy titles as Quantum ‘spookiness’ passes […]
