'Old smokers' and 'squalling newborns' among hidden stars spotted for first time      (via sciencedaily.com)     Original source 

'Hidden' stars including a new type of elderly giant nicknamed an 'old smoker' have been spotted for the first time by astronomers. The mystery objects exist at the heart of our Milky Way galaxy and can sit quietly for decades -- fading almost to invisibility -- before suddenly puffing out clouds of smoke, according to a new study.

Quantum infrared spectroscopy: Lights, detector, action!      (via sciencedaily.com)     Original source 

Researchers have incorporated an innovative ultra-broadband, quantum-entangled light source that generates a relatively wide range of infrared photons with wavelengths between 2 m and 5 m for dramatically downsizing the infrared spectroscopy system and upgrading its sensitivity. It can obtain spectra for various target samples, including hard solids, plastics, and organic solutions. This new technique uses the unique properties of quantum mechanics -- such as superposition and entanglement -- to overcome the limitations of conventional techniques.

Towards the quantum of sound      (via sciencedaily.com)     Original source 

A team of scientists has succeeded in cooling traveling sound waves in wave-guides considerably further than has previously been possible using laser light. This achievement represents a significant move towards the ultimate goal of reaching the quantum ground state of sound in wave-guides. Unwanted noise generated by the acoustic waves at room temperature can be eliminated. This experimental approach both provides a deeper understanding of the transition from classical to quantum phenomena of sound and is relevant to quantum communication systems and future quantum technologies.

Higher measurement accuracy opens new window to the quantum world      (via sciencedaily.com)     Original source 

A team has developed a new measurement method that, for the first time, accurately detects tiny temperature differences in the range of 100 microkelvin in the thermal Hall effect. Previously, these temperature differences could not be measured quantitatively due to thermal noise. Using the well-known terbium titanate as an example, the team demonstrated that the method delivers highly reliable results. The thermal Hall effect provides information about coherent multi-particle states in quantum materials, based on their interaction with lattice vibrations (phonons).

Solid-state qubits: Forget about being clean, embrace mess      (via sciencedaily.com)     Original source 

New findings debunk previous wisdom that solid-state qubits need to be super dilute in an ultra-clean material to achieve long lifetimes. Instead, cram lots of rare-earth ions into a crystal and some will form pairs that act as highly coherent qubits, a new paper shows.
