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 […]
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 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, […]
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 […]
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 […]
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 […]
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 […]
A hot topic of research nowadays is the energy transfer in quantum systems. One important reason for this interest is the famous 2007 experiment that suggests quantum effects in the dynamics of the photosynthetic complex FMO, from the green sulfur […]
Quantum mechanics represented a revolution in physics with implications in many other fields like chemistry and biology. It also conducted changes on some of the main scientific lines of thought, including a farewell to determinism. In the science before quantum […]
As we have discussed in our previous post, there is an important debate in the scientific community regarding the existence of negative absolute temperatures. The debate is not over, and both sides have valuable arguments, but in any case, […]
