An international collaboration involving European, Israeli, and US scientists realize for the first time strong and directionally dependent interactions in quantum liquids of excitons, which contrasts with the spatial isotropy of the coupling between charged particles. This spatial anisotropy affects the way particles arrange themselves in space and opens routes to artificially created exotic states of matter. The results were published…

28 years old and closer than ever to the solving of the mistery of the Majorana particles
Gazibegović, Ph.D. candidate in the group of prof. Erik Bakkers at the department of Applied Physics, developed a device made of ultrathin networks of nanowires in the shape of “hashtags.” This device allows pairs of Majorana particles to exchange position and keep track of the changes occurred, in a phenomenon known as “braiding.” This event is considered as a striking proof…

Discrete energy levels without confinement – a new quantum trick
Nanostructures can be designed such a way that the quantum confinement allows only certain electron energy levels. Researchers from IMDEA Nanociencia, UAM and ICMM-CSIC have, for the first time, observed a discrete pattern of electron energies in an unconfined system, which could lead to new ways of modifying the surface properties of materials. …
S-money: Ultra-secure form of virtual money proposed
A new type of money that allows users to make decisions based on information arriving at different locations and times, and that could also protect against attacks from quantum computers, has been proposed by a researcher at the University of Cambridge. …
Quantum computing with graphene plasmons
A novel material that consists of a single sheet of carbon atoms could lead to new designs for optical quantum computers. Physicists from the University of Vienna and the Institute of Photonic Sciences in Barcelona have shown that tailored graphene structures enable single photons to interact with each other. The proposed new architecture for quantum computer is published in the recent…
A novel technique that uses quantum light to measure temperature at the nanoscale
Being able to measure, and monitor, temperatures and temperature changes at miniscule scales—inside a cell or in micro and nano-electronic components—has the potential to impact many areas of research from disease detection to a major challenge of modern computation and communication technologies, how to measure scalability and performance in electronic components. …
Quantum sensor for photons
A photodetector converts light into an electrical signal, causing the light to be lost. Researchers led by Tracy Northup at the University of Innsbruck have now built a quantum sensor that can measure light particles non-destructively. It can be used to further investigate the quantum properties of light. …
A quantum leap in particle simulation
A group of scientists at the Department of Energy’s Fermilab has figured out how to use quantum computing to simulate the fundamental interactions that hold together our universe. …
Machine learning paves the way for next-level quantum sensing
Researchers at the University of Bristol have reached new heights of sophistication in detecting magnetic fields with extreme sensitivity at room temperature by combining machine learning with a quantum sensor. …
