Fused Silica Nanofabricated Chips May Help Reduce Size and Cost of Future High-Energy Particle Colliders

In an advance that could dramatically shrink particle accelerators for science and medicine, researchers used a laser to accelerate electrons at a rate 10 times higher than conventional technology in a nanostructured glass chip smaller than a grain of rice.

Quantum Light Source Coaxed to Emit Ultrashort Burst of Light at a Desired Moment in Time

Usually, an elementary light source – such as an excited atom or molecule – emits light at an unpredictable instance in time. This spontaneous emission of light is a fundamental process within applications such as LEDs and lasers. However, for other applications it is desirable to receive single photons (light) at a specific moment with as little uncertainty as possible.

Scientists Observe Elementary Quantum Magnetic Phenomena in Ferromagnetic Quantum Crystals

Simulating solid state properties with precisely controlled quantum systems is an important goal of the Quantum Many-Body Systems Division at MPQ. Now the team around Professor Immanuel Bloch (Chair for Experimental Physics at the Ludwig-Maximilians-Universität Munich and Director at MPQ) has come again a step closer to it – to be precise, to the understanding of processes in ferromagnetic solid state crystals in which elementary excitations, so-called magnons, can emerge.

A Way to Translate Electrical Quantum States to Optical Quantum States

Fiber optics has made communication faster than ever, but the next step involves a quantum leap –– literally. In order to improve the security of the transfer of information, scientists are working on how to translate electrical quantum states to optical quantum states in a way that would enable ultrafast, quantum-encrypted communications.

Laboratory Simulation of Deep Earthquakes Using Synchrotron X-Rays

More than 20 years ago, geologist Harry Green, now a distinguished professor of the graduate division at the University of California, Riverside, and colleagues discovered a high-pressure failure mechanism that they proposed then was the long-sought mechanism of very deep earthquakes (earthquakes occurring at more than 400 km depth).

Supercomputers Used to Map Nuclear Phase Diagram

To get a better understanding of the subatomic soup that filled the early universe, and how it “froze out” to form the atoms of today’s world, scientists are taking a closer look at the nuclear phase diagram. Like a map that describes how the physical state of water morphs from solid ice to liquid to steam with changes in temperature and pressure, the nuclear phase diagram maps out different phases of the components of atomic nuclei—from the free quarks and gluons that existed at the dawn of time to the clusters of protons and neutrons that make up the cores of atoms today.

Scientists Progress Towards Cavity-Based Interface With an Ion-Trap Quantum Computer

A team of scientists in Innsbruck, Austria, made an important step toward distributed quantum computing with cavities linking remote atom-based registers. They demonstrated precise control of the coupling of each of two trapped ions to the mode of an optical resonator.

Quantum Technologies will Offer Ultra-Secure Communications, Precise Sensors and More Powerful Computers

The ability to design and create new materials and pharmaceuticals at a fraction of today’s costs is just one of the possibilities that were described by Professor Jeremy O’Brien at the World Economic Forum meeting of the New Champions 2013 held in Dalian, China.

FQXi Awards Grant for Research on Structure of Quantum Information with Neutron Interferometry

The Foundational Questions Institute (FQXi) awards grants to “catalyze, support, and disseminate research on questions at the foundations of physics and cosmology”. The grant awarded to Emerson and his collaborators was one of 37 applications selected for funding this year from a total of 211 initial applications that were submitted by institutions, universities, colleges, laboratories, think tanks and businesses from around the world.
