Your press review from Quantaneo

Must read! An article in French by Julien Bourdet in the CNRS magazine: "Ordinateur : les promesses de l'aube quantique". An excellent article both accurate and popular on the issues involved in quantum computing, and the challenges that remain to be addressed. Also, worth listening to is a TedTalk by Shohini Ghose, which explains in ten minutes, the potential of quantum computing, through the usual examples. The video dates from 2018 but is well worth 10 minutes of your time.
 
From predicting photon trajectories to predicting the future, the step is high. But you have to start with the photons first! A team of physicists from Nanyang University of Technology (NTU) in Singapore and Griffith University in Australia have created a quantum photonic information processor, capable of determining the possible paths of unique photons of light, at the same time, using quantum superposition and ranking them in order of probability. On a long-term basis, the multiplication of computing power of quantum processors would make it possible to multiply the analysis of possibilities and thus to calculate all possible scenarios.
 
At the University of Oregon, in the United States, physicists have succeeded in creating artificial atoms and manipulating them at room temperature. They did this by drilling holes 500 nanometers wide and 4 nanometers deep in a thin, two-dimensional sheet of hexagonal boron nitride. They were then able to observe the unit photon emission. Quantum computing, when it will possible at room temperature, would have taken an important step towards the democratization of its uses.
