Scientists have demonstrated entanglement and two-particle interference with phonon using an acoustic beam splitter.

Phonons are to sound what photons are to light. Photons are tiny packets of energy for light or electromagnetic waves. Similarly, phonons are packets of energy for sound waves. Each phonon represents the vibration of millions of atoms within a material.

Both photons and phonons are of central interest to quantum computing research, which exploits the properties of these quantum particles. However, phonons have proven challenging to study due to their susceptibility to noise and issues with scalability and detection.

Quantum information (QI) processing may be the next game changer in the evolution of technology, by providing unprecedented computational capabilities, security and detection sensitivities. Qubits, the basic hardware element for quantum information, are the building block for quantum computers and quantum information processing, but there is still much debate on which types of qubits are actually the best.

Research and development in this field is growing at astonishing paces to see which system or platform outruns the other. To mention a few, platforms as diverse as superconducting Josephson junctions, trapped ions, topological qubits, ultra-cold neutral atoms, or even diamond vacancies constitute the zoo of possibilities to make qubits.

So far, only a handful of platforms have been demonstrated to have the potential for quantum computing, marking the checklist of high-fidelity controlled gates, easy qubit-qubit coupling, and good isolation from the environment, which means sufficiently long-lived coherence.

It took less than a second to solve a puzzle that super computers would take five years to solve.

A quantum computer, Juizhang, built by a team led by Pan Jianwei, has claimed that it can process artificial intelligence (AI) related tasks 180 million times faster, the South China Morning Post.

Even as the US celebrates its lead in the list of TOP500 supercomputers in the world, China has been slowly building its expertise in the next frontier of computing — quantum computing. Unlike conventional computing, where a bit-the smallest block of information can either exist as one or zero, a bit in quantum computing can exist in both states at once.

An international research team has succeeded for the first time in measuring the electron spin in matter—i.e., the curvature of space in which electrons live and move—within “kagome materials,” a new class of quantum materials.

The results obtained—published in Nature Physics —could revolutionize the way quantum materials are studied in the future, opening the door to new developments in quantum technologies, with in a variety of technological fields, from to biomedicine, from electronics to quantum computers.

Success was achieved by an international collaboration of scientists, in which Domenico Di Sante, professor at the Department of Physics and Astronomy “Augusto Righi,” participated for the University of Bologna as part of his Marie Curie BITMAP research project. He was joined by colleagues from CNR-IOM Trieste, Ca’ Foscari University of Venice, University of Milan, University of Würzburg (Germany), University of St. Andrews (UK), Boston College and University of Santa Barbara (U.S.).

Scientists from the Radboud University have developed synthetic molecules that resemble real organic molecules. A collaboration of researchers, led by Alex Khajetoorians and Daniel Wegner, can now simulate the behavior of real molecules by using artificial molecules. In this way, they can tweak properties of molecules in ways that are normally difficult or unrealistic, and they can understand much better how molecules change.

Their paper is published in the journal Science.

Emil Sierda, who was in charge of conducting the experiments at Radboud University said, “A few years ago we had this crazy idea to build a . We wanted to create that resembled real molecules. So we developed a system in which we can trap electrons. Electrons surround a molecule like a cloud, and we used those trapped electrons to build an artificial molecule.” The results the team found were astonishing. Sierda says, “The resemblance between what we built and real molecules was uncanny.”
