The sending-or-not-sending twin-field (SNS-TF) protocol has so far proved to be a highly promising strategy for achieving high rates over long distances in quantum key distribution (QKD) applications. In fact, by tolerating large misalignment errors, this protocol can...

A theoretical approach to understand the mechanisms of 3-D spatiotemporal mode-locking
Laser technology confines light inside a resonator containing a gain medium, a material with quantum properties that can amplify light. As laser resonators are generally far larger than the wavelength of light, lasing inside their cavities can occur in a wide range of...
Reviewing recent developments in the electrolysis of saline water
Solar-powered technology, such as photovoltaics (PVs), could address some of the environmental challenges of our times, enabling the sustainable production of electrical energy in many geographical areas, including arid or desert regions. Many arid regions are located...
Cooling of a trapped ion to the quantum regime
Neutral atoms and charged ions can be cooled down to extremely low temperatures (i.e., to microkelvins, 1 millionth of a degree above absolute zero) using laser techniques. At these low temperatures, the particles have often been found to behave in accordance with the...
Compact dark object search: Scanning Earth’s core with superconducting gravimeters
Physics theory suggests that the universe is made up in great part by a type of matter that does not emit, absorb or reflect light, and hence cannot be observed using conventional detection methods. This type of matter, referred to as dark matter, has so far never...
3-D imaging the flavor content of the nucleon
The Jefferson Lab Hall A Collaboration, in an experiment led by researchers at Faculté des Sciences de Monastir in Tunisia, Institut de Physique Nucléaire d'Orsay in France and Old Dominion University in the United States, has recently gathered the first experimental...

Precise measurements find a crack in universal physics
The concept of universal physics is intriguing, as it enables researchers to relate physical phenomena in a variety of systems, irrespective of their varying characteristics and complexities. Ultracold atomic systems are often perceived as ideal platforms for...
The experimental observation of echoes in a single molecule
Echoes, sounds that are repeated or reverberate as a result of waves reflected back to the listener, occur in several physical systems. In physics research, echoes are typically used to eliminate the effects of dephasing caused by a system's interactions with the...
Investigating dynamics of democratic elections using physics theory
Sometimes, physics theories and constructs can also be used to study seemingly unrelated phenomena, such as social behaviors or dynamics. While human beings are not necessarily similar to specific physical particles, theories or techniques that physicists typically...
