Uncovering the nature of emergent magnetic monopoles

 Quantum Physics News
 12 June 2024
To understand the unique physical phenomena associated with the properties of magnetic hedgehogs and antihedgehogs, which behave as virtual magnetic monopoles and antimonopoles respectively, it is essential to study their intrinsic excitations. In a new study, researchers revealed the dynamical...

Switching nanomagnets using infrared lasers

 Quantum Physics News
 11 June 2024
Physicists have calculated how suitable molecules can be stimulated by infrared light pulses to form tiny magnetic fields. If this is also successful in experiments, the principle could be used in quantum computer circuits....

The coldest lab in New York has new quantum offering

 Quantum Physics News
 03 June 2024
Physicists describe the successful creation of a molecular Bose-Einstein condensate (BEC). Made up of dipolar sodium-cesium molecules that were cooled with the help of microwave shielding to just 5 nanoKelvin and lasted for up to two seconds, the new molecular BEC will help scientists explore a...

Scientists develop most sensitive way to observe single molecules

 Quantum Physics News
 30 May 2024
A technical achievement marks a significant advance in the burgeoning field of observing individual molecules without the aid of fluorescent labels. While these labels are useful in many applications, they alter molecules in ways that can obscure how they naturally interact with one another. The new...

The thinnest lens on Earth, enabled by excitons

 Quantum Physics News
 30 May 2024
Lenses are used to bend and focus light. Normal lenses rely on their curved shape to achieve this effect, but physicists have made a flat lens of only three atoms thick which relies on quantum effects. This type of lens could be used in future augmented reality glasses....

Study is step towards energy-efficient quantum computing in magnets

 Quantum Physics News
 29 May 2024
Researchers have managed to generate propagating spin waves at the nanoscale and discovered a novel pathway to modulate and amplify them. Their discovery could pave the way for the development of dissipation free quantum information technologies. As the spin waves do not involve electric currents...

More than spins: Exploring uncharted territory in quantum devices

 Quantum Physics News
 24 May 2024
Many of today's quantum devices rely on collections of qubits, also called spins. These quantum bits have only two energy levels, the '0' and the '1'. However, spins in real devices also interact with light and vibrations known as bosons, greatly complicating calculations. Researchers now...
