Attosecond Core-Level Spectroscopy Reveals Real-Time Molecular Dynamics

May 7, 2024
A team of European researchers has developed an attosecond core-level spectroscopy technique that can track the many-body molecular dynamics on its natural ultrafast timescale. Their work was benchmarked with furan, showing the power of their tool by successfully retrieving the entire history evolution of the dynamics and relaxation processes of a heterocyclic organic ring.

MIT physicists developed a technique to arrange atoms in much closer proximity than previously possible, down to 50 nanometers. The group plans to use the method to manipulate atoms into configurations that could generate the first purely magnetic quantum gate — a key building block for a new type of quantum computer.

The "thorium transition", which physicists have been looking for for decades, has now been excited for the first time with lasers. This paves the way for revolutionary high precision technologies, including nuclear clocks.

An Elegant Method for the Detection of Single Spins Using Photovoltage

An Elegant Method for the Detection of Single Spins Using Photovoltage

April 16, 2025
Diamonds with certain optically active defects can be used as highly sensitive sensors or qubits for quantum computers, where the quantum information is stored in the electron spin state of these colour centres. However, the spin states have to be read out optically, which is often experimentally complex. Now, a team at HZB has developed an elegant method using a photo voltage to detect the individual and local spin states of these defects. This could lead to a much more compact design of quantum sensors.

Maximal Entanglement Sheds New Light on Particle Creation

Maximal Entanglement Sheds New Light on Particle Creation

April 13, 2025
Physicists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and Stony Brook University (SBU) have shown that particles produced in collimated sprays called jets retain information about their origins in subatomic particle smashups. The study was recently published as an Editor’s Suggestion in the journal Physical Review Letters.

Nuclear Spins Tamed for Quantum Applications

Nuclear Spins Tamed for Quantum Applications

April 13, 2025
Nuclear spins in a crystal can be detected and manipulated through their interactions with the more accessible electron spin of a neighboring crystal defect. This strategy has enabled nanoscale magnetic resonance imaging and other quantum applications. But a long-standing challenge has been to target a specific nuclear spin, while protecting the delicate quantum nature of the electron spin. Important progress on this challenge has now been achieved by two teams at the Delft University of Technology in the Netherlands.

Researchers Unlock Hidden Pathway to Tunable Magnetic Devices

April 10, 2025
A new study published in Nature Communications April 7 could reshape the future of magnetic and electronic technology. Scientists at Rice University have discovered how a disappearing electronic pattern in a quantum material can be revived under specific thermal conditions. The finding opens new doors for customizable quantum materials and in-situ engineering, where devices are manufactured or manipulated directly at their point of use.
