Using sound and light to generate ultra-fast data transfer

Researchers have made a breakthrough in the control of terahertz quantum cascade lasers, which could lead to the transmission of data at the rate of 100 gigabits per second – around one thousand times quicker than a fast Ethernet operating at 100 megabits a second. What distinguishes terahertz quantum cascade lasers from other lasers is … Read more Using sound and light to generate ultra-fast data transfer

Breakthrough made on the next big step to building the world’s most powerful particle accelerator

For the first time scientists have observed muon ionization cooling – a major step in being able to create the world’s most powerful particle accelerator. This new muon accelerator will give us a better understanding of the fundamental constituents of matter. Since the 1930s, accelerators have been used to make ever more energetic proton, electron, … Read more Breakthrough made on the next big step to building the world’s most powerful particle accelerator

A quantum of solid

It is well known that quantum properties of individual atoms can be controlled and manipulated by laser light. Even large clouds of hundreds of millions of atoms can be pushed into the quantum regime, giving rise to macroscopic quantum states of matter such as quantum gases or Bose-Einstein condensates, which nowadays are also widely used … Read more A quantum of solid

Tuning optical resonators gives researchers control over transparency

In the quantum realm, under some circumstances and with the right interference patterns, light can pass through opaque media. This feature of light is more than a mathematical trick; optical quantum memory, optical storage and other systems that depend on interactions of just a few photons at a time rely on the process, called electromagnetically … Read more Tuning optical resonators gives researchers control over transparency

Influential electrons? Physicists uncover a quantum relationship

A team of physicists has mapped how electron energies vary from region to region in a particular quantum state with unprecedented clarity. This understanding reveals an underlying mechanism by which electrons influence one another, termed quantum “hybridization,” that had been invisible in previous experiments. The findings, the work of scientists at New York University, the … Read more Influential electrons? Physicists uncover a quantum relationship

Penn shows giving entire course of radiation treatment in less than a second is feasible

Cancer patients may one day be able to get their entire course of radiation therapy in less than a second rather than coming in for treatment over the course of several weeks, and researchers in the Abramson Cancer Center of the University of Pennsylvania have taken the first steps toward making it a reality. In … Read more Penn shows giving entire course of radiation treatment in less than a second is feasible

Stanford researchers build a particle accelerator that fits on a chip

On a hillside above Stanford University, the SLAC National Accelerator Laboratory operates a scientific instrument nearly 2 miles long. In this giant accelerator, a stream of electrons flows through a vacuum pipe, as bursts of microwave radiation nudge the particles ever-faster forward until their velocity approaches the speed of light, creating a powerful beam that … Read more Stanford researchers build a particle accelerator that fits on a chip

QuTech realises ‘MRI on the atomic scale’

Researchers at QuTech, a collaboration of TU Delft and TNO, have developed a new magnetic quantum sensing technology that can image samples with atomic-scale resolution. It opens the door towards imaging individual molecules, like proteins and other complex systems, atom by atom. The team reports on their results in Nature. Magnetic resonance Magnetic Resonance Imaging (MRI) and … Read more QuTech realises ‘MRI on the atomic scale’

Protein imaging at the speed of life

To study the swiftness of biology – the protein chemistry behind every life function – scientists need to see molecules changing and interacting in unimaginably rapid time increments – trillionths of a second or shorter. Imaging equipment with that kind of speed was finally tested last year at the European X-ray Free-Electron Laser, or EuXFEL. … Read more Protein imaging at the speed of life

A remote control for everything small

They are reminiscent of the “tractor beam” in Star Trek: special light beams can be used to manipulate molecules or small biological particles. Even viruses or cells can be captured or moved. However, these optical tweezers only work with objects in empty space or in transparent liquids. Any disturbing environment would deflect the light waves … Read more A remote control for everything small
