Dancing to invisible choreography, quantum computers can balance the noise

Large-scale quantum computers are waiting in the wings. One of the main reasons we don't have them yet is because quantum hardware is so noisy. This isn't the type of noise you'd want to shush in a crowded theater. When it ...

A Hall 'rectenna' can detect signals over a 100 GHz frequency range

Many current wireless communication, imaging and sensing technologies rely on components that convert oscillating electric and magnetic fields (i.e., electromagnetic waves) into electrical signals. Some of the most used components ...

Saturday Citations: Merging brown dwarfs, ancient machine guns, gravitational wave detection

This week, among a lot of other important findings, we learned that emperor cichlid fish have gaze sensitivity and dislike it if you look at them—or especially their children. England is looking for a solution to its 5-billion-liter ...

Gravitational waves leave imprints on light emitted by atoms, theoretical study predicts

Gravitational waves are ripples in spacetime produced by violent cosmic events, such as the merging of black holes. So far, direct detections have relied on measuring tiny distance changes over kilometer-scale instruments. ...

Experiment observes quantum radiation reaction as electrons hit an ultra-intense laser

For the first time, a quantum radiation reaction in strong electromagnetic fields has been demonstrated experimentally by allowing electrons to collide with an extremely intense and powerful laser beam. The research findings ...

Breathing in nanoparticles could enable a 10-minute pneumonia check at point of care

Diagnosing some diseases could be as easy as breathing into a tube. MIT engineers have developed a test to detect disease-related compounds in a patient's breath. The new test could provide a faster way to diagnose pneumonia ...
