Polynomials against quantum computers

Governments and multinationals are investing large amounts of money in the construction of the quantum computer; Today IBM and Google are the most advanced in this direction. These computers can perform quantum simulation to model complex chemical reactions, or design new drugs, operations that are beyond the reach of the most powerful binary computers. But…… Continue reading Polynomials against quantum computers

Mathematics to improve the efficiency and design of quantum machines

The work could be applied in the design of thermometers for small quantum devices at low temperatures. The next great revolution in data processing goes through quantum physics, that part of physics that studies how the smallest elements, such as atoms and quarks, behave. However, scientists have not yet come up with all the keys…… Continue reading Mathematics to improve the efficiency and design of quantum machines

Interview to Prof. Rainer Blatt Research Director of the Institute for Quantum Optics and Quantum Information (IQOQI), Innsbruck, Austria

Experimental physicist Rainer Blatt, Research Director of IQOQI has carried out trail-blazing experiments in the fields of precision spectroscopy, quantum metrology and quantum information processing. He works with atoms caught in ion traps which he manipulates using laser beams. This work is based on suggestions made in the mid 1990s by theorists Ignacio Cirac and…… Continue reading Interview to Prof. Rainer Blatt Research Director of the Institute for Quantum Optics and Quantum Information (IQOQI), Innsbruck, Austria

The best measure of antimatter

Scientists from the ALPHA experiment at the European Particle Physics Laboratory (CERN) have taken the most accurate measurement of antimatter recorded to date. The advance has been achieved with about 15,000 atoms of antihydrogens magnetically trapped in a cylinder. One of the challenges physicists face is to explain why matter survived antimatter after the Big…… Continue reading The best measure of antimatter
