Physicists Reveal Mechanism for Stimulating the Production of Entanglement in the Hawking Effect

LSU physicists have leveraged quantum information theory techniques to reveal a mechanism for amplifying, or "stimulating," the production of entanglement in the Hawking effect in a controlled manner. Furthermore, these scientists propose a protocol for testing this idea in the laboratory using artificially produced event horizons.

Breakdown of Topological Protection by Vacuum Fluctuations in the Integer Quantum Hall Effect

"Up to 1980 nobody expected that there exists an effect like the Quantized Hall Effect, which depends exclusively on fundamental constants and is not affected by irregularities in the semiconductor like impurities or interface effects." So spoke the German physicist Klaus von Klitzing on receiving the 1985 Nobel Prize in Physics. He was recognised for his discovery, in 1980, of a quantised version of the Hall effect in two-dimensional electron gases.

Analysis of Cosmic Dust Brings Scientists One Step Closer to Quantum and Magnonic Devices

New research published in Science brings us a step closer to magnonic devices and quantum computing. Neutron analysis has revealed the behaviour of magnetic waves in a class of materials, enabling scientists to picture a future where electronic currents no longer cause our devices to heat up.

Novel Method to Acquire Quantum Metrology Precision Without Using Entangled Resources

A majority of quantum information tools together with quantum computers, which are regarded as a level above supercomputers, and quantum communication that is unable to hack are founded on the quantum entanglement principle. Nevertheless, entangled systems are present in a small microscopic world, and they are quite delicate.

Study Demonstrates the Potential of Plasma as Energy Booster for High-Gradient Accelerators

An international team of scientists guided by Deutsches Elektronen-Synchrotron (DESY) researchers has shown, for the first time at the FLASHForward experiment that in principle, it is possible to work plasma accelerators at the repetition rates preferred by particle physicists and photon experts.

Oscillation Mechanism of Self-Sustained Divertor Observed in Fusion Plasma Experiment

To control the forces that power the Sun to generate significant clean energy on Earth, scientists heat fuel to an extremely high temperature causing atoms to melt into electrons and nuclei to produce a hot, gaseous soup referred to as plasma.

Creating a Hybrid Array of Neutral Atoms Opens the Door to Many Quantum Applications

Qubits, the building blocks of quantum computers, can be made from many different technologies. One way to make a qubit is to trap a single neutral atom in place using a focused laser, a technique that won the Nobel Prize in 2018.

A Coherent View of Lattice and Code-Based Cryptography in the Context of Post-Quantum Cryptography

Cryptography is a subject area of long history, playing a crucial role in human society ever since the dawn of civilization. Claude Shannon's 1945 paper ``A Mathematical Theory of Cryptography'' is widely regarded as the beginning of modern cryptography, as a new science. In 1949, Shannon published another landmark paper ``A Mathematical Theory of Communication'', founding the area of Information Theory.

New Strategy to Control the Orientation of an Unpaired Spin in a Molecule

Controlling the orientation of a single unpaired electron (called its spin) is no easy task, especially if the electron is in a molecule in its lowest energy state. Yet the ability to control the orientation of the electrons is important to the development of some quantum computing strategies.
