Anton Zeilinger, a renowned quantum physicist, recently said: "Personally, I believe that in the future, most, if not all, communications will be quantum." China has already taken steps to make the quantum internet a reality, as is the United States. Unfortunately, quantum computing is lagging behind as several tech giants (including IBM and Google) struggle to add more and more qubits to their machines. But a new study has revealed that the key to creating more powerful quantum computers may not have been adding more qubits he may be shaping more complex qubits.
The qubits look like normal computer bits, but with a possible additional state equal to 0 and 1 at the same time. Since most quantum computers are assembled between 50 and 75 qubits maximum, the information capacity of the entire system is quite small. In addition, these qubits are only entangled in two dimensions, which further limits the amount of information that they can handle. Researchers from the University of Vienna and the Austrian Academy of Sciences decided to look for new ways to fix and confuse the qubits and discovered that it was possible to confuse three particles in three dimensions. After some difficulties in designing the experience, the team was able to achieve its goal.
"The peculiarity of our experience is that, for the first time, it entangles three photons beyond conventional two-dimensional nature," says Manuel Erhard, one of the authors of the study. What comes next can change not only the face of quantum computing, but also that of quantum telecommunication. According to Anton Zeilinger, author of the study, "I think that the methods and technologies we have developed in this publication allow us to teleport a higher proportion of the total quantum information of a photon, which could to be important Communication Networks.
