Hello, world! A new approach for physics in de Sitter space

For decades, physicists have been attempting to reconcile quantum mechanics, the physics of the very small, with gravity, the physics of the very large. While many academics are working on quantum gravity, they often use ...

New method for detecting quantum states of electrons

Quantum computing harnesses enigmatic properties of small particles to process complex information. But quantum systems are fragile and error-prone, and useful quantum computers have yet to come to fruition.

A novel tool to probe fundamental matter

Identifying elementary constituents of matter including quarks, bosons and electrons, and the manner by which these particles interact with each other, constitutes one of the greatest challenges in modern physical sciences. ...

One step closer future to quantum computers

Physicists at Uppsala University in Sweden have identified how to distinguish between true and 'fake' Majorana states in one of the most commonly used experimental setups, by means of supercurrent measurements. This theoretical ...

Gravity surveys using a mobile atom interferometer

Mobile gravimetry is an important technique in metrology, navigation, geodesy and geophysics. Although atomic gravimeters are presently used for accuracy, they are constrained by instrumental fragility and complexity. In ...

Researchers advance noise cancelling for quantum computers

A team from Dartmouth College and MIT has designed and conducted the first lab test to successfully detect and characterize a class of complex, "non-Gaussian" noise processes that are routinely encountered in superconducting ...

New topological insulator reroutes photonic 'traffic' on the fly

Topological insulators are a game-changing class of materials; charged particles can flow freely on their edges and route themselves around defects, but can't pass through their interiors. This perfect surface conduction ...

JILA's novel atomic clock design offers 'tweezer' control

JILA physicists have demonstrated a novel atomic clock design that combines near-continuous operation with strong signals and high stability, features not previously found together in a single type of next-generation atomic ...

Probing a nuclear clock transition

Modern atomic clocks are the most accurate measurement tools currently available. The best current instruments deviate by just one second in 30 billion years. However, even this extraordinary level of precision can be improved ...

Introducing quantum convolutional neural networks

Machine learning techniques have so far proved to be very promising for the analysis of data in several fields, with many potential applications. However, researchers have found that applying these methods to quantum physics ...

Getting a look under the hood of topological insulators

Certain materials, like copper, conduct electricity very well. Other materials, like glass, do not. A certain kind of material, called a topological insulator, acts partially like one and partially like the other ― it ...

Major steps forward in understanding neutrino properties

In the quest to prove that matter can be produced without antimatter, the GERDA experiment at the Gran Sasso Underground Laboratory in Italy is looking for signs of neutrinoless double beta decay. The experiment has the greatest ...

Exotic physics phenomenon is observed for first time

An exotic physical phenomenon, involving optical waves, synthetic magnetic fields, and time reversal, has been directly observed for the first time, following decades of attempts. The new finding could lead to realizations ...

Using correlated photons to enhance x-ray imaging

A team of researchers at Bar-Ilan University has found a way to use correlated photons to make sharper X-ray images. In their paper published in the journal Physical Review Letters, the group describes their process and suggest ...
