Physicists arrange atoms in close proximity, paving way for exploring exotic states of matter

2 mai

Proximity is key for many quantum phenomena, as interactions between atoms are stronger when the particles are close. In many quantum simulators, scientists arrange atoms as close together as possible to explore exotic states of matter and build new quantum materials.

Researcher creates optical magnetometer prototype that detects errors in MRI scans

2 mai

Hvidovre Hospital has the world’s first prototype of a sensor capable of detecting errors in MRI scans using laser light and gas. The new sensor, developed by a young researcher at the University of Copenhagen and Hvidovre Hospital, can thereby do what is impossible for current electrical (…)

Good vibrations : Low-energy lasers induce atomic excitation in semiconductor materials

2 mai

Semiconductors are a cornerstone of next-generation technology, so a new method to excite atoms in semiconductor materials is likely to excite a broad range of researchers and industries as well.

Researchers unveil single-shot and complete polarization imaging system using metasurfaces

2 mai

Think of all the information we get based on how an object interacts with wavelengths of light—aka color. Color can tell us if food is safe to eat or if a piece of metal is hot. Color is an important diagnostic tool in medicine, helping practitioners diagnose diseased tissue, inflammation, or (…)

Significant new discovery in teleportation research : Noise can improve the quality of quantum teleportation

2 mai

Researchers have succeeded in conducting an almost perfect quantum teleportation despite the presence of noise that usually disrupts the transfer of quantum state. The results have been published in the journal Science Advances.

Research demonstrates high qubit control fidelity and uniformity in single-electron control

2 mai

The journal Nature has published a research paper, "Probing single electrons across 300-mm spin qubit wafers," demonstrating state-of-the-art uniformity, fidelity and measurement statistics of spin qubits. The industry-leading research opens the door for the mass production and (…)

Researchers find unexpected roadblock to conductivity in Mott insulators

2 mai

In the realm of condensed matter physics, few phenomena captivate physicists’ curiosity as much as Mott insulators. According to traditional theory, this odd class of materials should be capable of conducting electricity, yet they behave mostly as insulators.

Twisting and binding matter waves with photons in a cavity

2 mai

Precisely measuring the energy states of individual atoms has been a historical challenge for physicists due to atomic recoil. When an atom interacts with a photon, the atom "recoils" in the opposite direction, making it difficult to measure the position and momentum of the atom (…)

High-intensity spatial-mode steerable frequency up-converter toward on-chip integration

1er mai

A study published in Opto-Electronic Science discusses high-intensity spatial-mode steerable frequency up-converter toward on-chip integration.

Researchers build new device that is a foundation for quantum computing

1er mai

Scientists led by the University of Massachusetts Amherst have adapted a device called a microwave circulator for use in quantum computers, allowing them for the first time to precisely tune the exact degree of nonreciprocity between a qubit, the fundamental unit of quantum computing, and a (…)
