Two papers investigate the thermodynamics of quantum systems
Toward tinier transistors
(Phys.org) —The foundation of many, many modern electronic devices – including computers, smart phones, and televisions – is the silicon transistor. However, the shrinking of consumer electronics is ...
The quantum secret to alcohol reactions in space
Chemists have discovered that an 'impossible' reaction at cold temperatures actually occurs with vigour, which could change our understanding of how alcohols are formed and destroyed in space.
Large-scale quantum chip validated
A team of scientists at USC has verified that quantum effects are indeed at play in the first commercial quantum optimization processor.
Improving measurements by reducing quantum noise
If you want to measure something very precisely, such as slight variations of a length, then you are very likely to use light waves. However, many effects, such as variations of gravity, or surface forces, ...
Quantum information in low light: New photo-detection scheme makes do with few photons
(Phys.org) —At low light, cats see better than humans. Electronic detectors do even better, but eventually they too become more prone to errors at very low light. The fundamental probabilistic nature of ...
RHIC's perfect liquid a study in perfection
(Phys.org) —When heavy ions (the nuclei of heavy atoms such as gold and lead) collide at high energies at Brookhaven National Laboratory's Relativistic Heavy Ion Collider (RHIC) and Europe's Large Hadron Coll ...
Closing the last Bell-test loophole for photons
(Phys.org) —An international team of researchers has reached a milestone in experimental confirmation of a key tenet of quantum mechanics, using ultra-sensitive photon detectors devised by PML scientists.
Whispering light hears liquids talk: Scientists build first-ever bridge between optomechanics and microfluidics
Ever been to a whispering gallery—a quiet, circular space underneath an old cathedral dome that captures and amplifies sounds as quiet as a whisper? Researchers at the University of Illinois at Urbana-Champaign ...
Spooky action put to order: Physicists classify different types of 'entanglement'
A property known as "entanglement" is a fundamental characteristic of quantum mechanics. Physicists and mathematicians at ETH Zurich show now how different forms of this phenomenon can be efficiently and systematically classified ...
Spintronics approach enables new quantum technologies
(Phys.org) —A team of researchers including members of the University of Chicago's Institute for Molecular Engineering highlight the power of emerging quantum technologies in two recent papers published ...
May the force be with us? Precise measurements test quantum electrodynamics, constrain possible fifth fundamental force
Our ambiguous world of words
(Phys.org) —Ambiguity in language poses the greatest challenge when it comes to training a computer to understand the written word. Now, new research aims to help computers find meaning.
More precision from less predictability: A new quantum trade-off
An important advance in the quantitative understanding and experimental verification of complementarity; arguably the most important foundational principle of quantum mechanics.
