Approximate quantum cloning: The new way of eavesdropping in quantum cryptography

Cloning of quantum states is used for eavesdropping in quantum cryptography. It also has applications in quantum computation based on quantum information distribution. Uncertainty at the quantum scale makes exact cloning of quantum states impossible. Show More Summary


Conference: 23 Jul 2018 - 26 Jul 2018, Cork, Ireland.

Mystery honeycombs in rock may be created by water and salt

Many rocks are covered with circular hollows that look like honeycomb, and now we may finally understand how these strange formations come into existence

Fermilab organizes Hidden Figures STEM program for local students

At a showing of the blockbuster movie followed by a Q&A with Fermilab scientists, students from diverse backgrounds were encouraged to pursue STEM careers.

3D Non-Contact Optical Metrology Workshop

Workshop: 6 Mar 2018 - 7 Mar 2018, Bruker office in Leiderdorp, Netherlands, United Kingdom. Organized by Bruker Nano Surfaces.

Shedding high-power laser light on the plasma density limit

The interaction of high-power laser light sources with matter has given rise to numerous applications including; fast ion acceleration; intense X-ray, gamma-ray, positron and neutron generation; and fast-ignition-based laser fusion. These applications require an understanding of energy absorption and momentum transfer from the high-intensity lasers to plasma particles.

New method to determine molecule chirality

Identifying right-handed and left-handed molecules is a crucial step for many applications in chemistry and pharmaceutics. An international research team (CELIA-CNRS/INRS/Berlin Max Born Institute/SOLEIL) has now presented a new original and very sensitive method. Show More Summary

Using organoids to understand how the brain wrinkles

A team of researchers working at the Weizmann Institute of Science has found that organoids can be used to better understand how the human brain wrinkles as it develops. In their paper published in the journal Nature Physics, the team describes how they used a modified form of organoid development to study the development of brain wrinkles. Show More Summary

Add-on clip turns smartphone into fully operational microscope

Australian researchers from the ARC Centre of Excellence for Nanoscale BioPhotonics (CNBP) have developed a 3D printable 'clip-on' that can turn any smartphone into a fully functional microscope.

Collecting books

A collection of physics books is being sold to the American Institute of Physics for $5m, as Robert P Crease finds out

Computers aid discovery of new, inexpensive material to make LEDs with high color quality

A team led by engineers at the University of California San Diego has used data mining and computational tools to discover a new phosphor material for white LEDs that is inexpensive and easy to make. Researchers built prototype white LED light bulbs using the new phosphor. The prototypes exhibited better color quality than many commercial LEDs currently on the market.

Pattern formation—the paradoxical role of turbulence

The formation of self-organizing molecular patterns in cells is a critical component of many biological processes. Researchers from Ludwig-Maximilians-Universitaet (LMU) in Munich have proposed a new theory to explain how such patterns emerge in complex natural systems.

Unconventional superconductor may be used to create quantum computers of the future

With their insensitivity to decoherence, Majorana particles could become stable building blocks of quantum computers. The problem is that they only occur under very special circumstances. Now, researchers at Chalmers University of Technology have succeeded in manufacturing a component that is able to host the sought-after particles.

Converting heat into electricity with pencil and paper

Thermoelectric materials can use thermal differences to generate electricity. Now there is an inexpensive and environmentally friendly way of producing them with the simplest tools: a pencil, photocopy paper, and conductive paint. These...Show More Summary

Physics Week in Review: February 17, 2018

Among this week's physics highlights: using a quantum computer to improve election forecasting; physicists create a new form of light; and a hotly debated new paper claiming scaling laws aren't universal to complex networks. I wrote an article for New...

Researchers demonstrate promising method for improving quantum information processing

A team of researchers led by the Department of Energy's Oak Ridge National Laboratory has demonstrated a new method for splitting light beams into their frequency modes. The scientists can then choose the frequencies they want to work with and encode photons with quantum information. Show More Summary

Bringing a hidden superconducting state to light

A team of scientists has detected a hidden state of electronic order in a layered material containing lanthanum, barium, copper, and oxygen (LBCO). When cooled to a certain temperature and with certain concentrations of barium, LBCOShow More Summary

Hilbert Spaces and Their Relatives

Basics Language first: There is no such thing as the Hilbert space. Hilbert spaces can look rather different, and which one is used in certain cases is by no means self-evident. To refer to Hilbert spaces by a definite article is like saying the moon when talking about Jupiter, or the car on an automotive fair. […]
