First 3-D imaging of excited quantum dots
Understanding how the presence of defects localizes excited electronic states of quantum dots will help to advance the engineering of these nanoparticles, said Martin Gruebele from t...
Exploring the realistic nature of the wave function in quantum mechanics
The REIN states that the wave function of a quantum object is an actual state rather than a mere mathematical description—in other words, the quantum object in space exists in the fo...
Detecting the birth and death of a phonon
First, one such pulse is shot onto a diamond crystal to excite a single phonon inside it. Thanks to another detector, they now record photons that have reabsorbed the energy of the v...
‘Cataclysmic’ collision shaped Uranus’ evolution
Uranus was hit by a massive object roughly twice the size of Earth that caused the planet to tilt and could explain its freezing temperatures, according to new research. Astronomers ...
Building blocks to create metamaterials
Engineers at Caltech and ETH Zürich in Switzerland have created a method to systematically design metamaterials using principles of quantum mechanics. Before our work, there was no s...
Artificial intelligence techniques reconstruct mysteries of quantum systems
For the first time, physicists have demonstrated that machine learning can reconstruct a quantum system based on relatively few experimental measurements. That method works well for ...
Artificial agent designs quantum experiments
Credit: Harald Ritsch On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. This s...

A powerful guiding principle for topological quantum synthesis
Topological materials are a new, rapidly expanding family of quantum matter, which can be classified into topological insulators (TIs), topological crystalline insulators, topologica...
2-D tin (stanene) without buckling: A possible topological insulator
Nagoya University-led researchers produce 2D sheets of tin atoms predicted to have exotic uses in electronics. Because of relatively strong spin-orbit interactions for electrons in h...
‘Weyl-Kondo semimetal’: Physicists discover new type of quantum material
In a new study due this week in the Early Edition of the Proceedings of the National Academy of Sciences (PNAS), Rice University theoretical physicist Qimiao Si and colleagues at the...
The bizarre world of topological materials
In 2016, three physicists received the Nobel Prize for using the mathematical concept of topology to explain the strange behavior of certain materials—for example, those that are ins...
Single-photon detector can count to 4
DURHAM, N.C. – Engineers have shown that a widely used method of detecting single photons can also count the presence of at least four photons at a time. The study was a collaboratio...
Researchers develop silicon chip-based quantum photonic devices
They used a hybrid approach combining silicon photonic waveguides with InAs/InP quantum dots that act as efficient sources of single photons at telecom wavelengths spanning the O-ban...
Controlling photons with a photon
Vacuum chamber with high-finesse optical resonator and cold atoms. In order to take full advantage of quantum information carried by photons, it is important to make them directly in...
Complete design of a silicon quantum computer chip unveiled
Credit: Tony Melov/UNSW Research teams all over the world are exploring different ways to design a working computing chip that can integrate quantum interactions. This would allow a...
CMS releases more than one petabyte of open data
CMS researchers have recorded petabytes of data from collisions at the LHC and have so far published hundreds of scientific papers with them. By releasing the data into the public do...
BepiColombo launch to Mercury
Animation visualising BepiColombo’s launch and cruise to Mercury. Some aspects have been simplified for the purpose of this animation. The joint ESA-JAXA mission comprises the Europe...
Benefits of Automated Testing
Automated testing reduced cycle time. As a testing cloud platform, we enable our clients to test across a variety of browsers and devices. Every piece of code that goes to testing ha...
An Introduction to Quantum Computing
The laws of physics are different at the atomic level and the classic laws of physics that we can observe in our daily life won’t apply here. What Is a Quantum Computer? What Is a Qu...
Writing and deleting magnets with lasers
A strong laser pulse disrupts the arrangement of atoms in an alloy and creates magnetic structures (left). The reversibility of the process opens up new possibilities in the fields o...
World’s first intra-operative MRI-guided robot for bilateral stereotactic neurosurgery
It involves a technique that can locate targets of surgical interest using an external positioning system, which is widely applied in brain biopsy, tumor ablation, drug delivery, as ...
Within 10 years, a high-luminosity LHC at CERN
Credit: Cyril Fresillon/LHC/CNRS Photothèque A new site opened on Friday, June 15, 2018, at the LHC, the Large Hadron Collider. Begun in 2011, this project aims to commission a high...
Why we need erasable MRI scans
Caltech’s Mikhail Shapiro and his colleagues have developed erasable MRI contrast agents that can blink off on command with ultrasound technology. As illustrated here, the contrast a...
Why plants are so sensitive to gravity: The lowdown
Credit: Yoel Forterre/Olivier Pouliquen/PNAS Plants can detect the slightest angle of inclination. In theory, such a system should hardly allow for precise detection of inclination....
