Quantum-entangled light from a vibrating membrane

0
Entanglement, a powerful form of correlation among quantum systems, is an important resource for quantum computing. Researchers from the Quantum Optomechanics group at the...

High Altitude Water Cherenkov observatory tests speed of light

0
New measurements confirm, to the highest energies yet explored, that the laws of physics hold no matter where you are or how fast you're...

Tiny optical cavity could make quantum networks possible

0
Engineers at Caltech have shown that atoms in optical cavities—tiny boxes for light—could be foundational to the creation of a quantum internet. Their work...

Tree rings could pin down Thera volcano eruption date

0
Charlotte Pearson's eyes scanned a palm-sized chunk of ancient tree. They settled on a ring that looked "unusually light," and she made a note...

Skyrmion ‘whirls’ show promise for low-energy computer circuitry

0
UNSW material scientists have shed new light on a promising new way to store and process information in computers and electronic devices that could...

New metabolism discovered in bacteria

0
They make sauerkraut sour, turn milk into yogurt and cheese, and give rye bread its intensive flavour: bacteria that ferment nutrients instead of using...

Researchers discover a novel chemistry to protect our crops from fungal disease

0
Pathogenic fungi pose a huge and growing threat to global food security. Currently, we protect our crops against fungal disease by spraying them with anti-fungal chemistries, also...

Physicists develop new photon source for tap-proof communication

0
An international team with the participation of Prof. Dr. Michael Kues from the Cluster of Excellence PhoenixD at Leibniz University Hannover has developed a...

Energy-harvesting design aims to turn Wi-Fi signals into usable power

0
Any device that sends out a Wi-Fi signal also emits terahertz waves —electromagnetic waves with a frequency somewhere between microwaves and infrared light. These...

Quantum copycat: Researchers find a new way in which bosons behave like fermions

0
Bosons and fermions, the two classes into which all particles—from the sub-atomic to atoms themselves—can be sorted, behave very differently under most circumstances. While...

Double-walled nanotubes have electro-optical advantages

0
One nanotube could be great for electronics applications, but there's new evidence that two could be tops. Rice University engineers already knew that size matters...
