A framework to self-test all entangled states using quantum networks
Self-testing is a promising method to infer the physics underlying specific quantum experiments using only collected measurements. While this method can be used to examine bipartite pure entangled states, so far it could only be applied to limited kinds of quantum...
The final results of the Majorana collaboration’s search for neutrinoless double-beta decay
For more than half a decade, the Majorana Collaboration, a large consortium of researchers from different universities worldwide, have been trying to observe neutrinoless double-beta decay, one of the rarest forms of radioactive decay. This was done using the Majorana...
The experimental realization of quantum overlapping tomography
Quantum tomography is a process that involves the reconstruction and characterization of a quantum state using a series of collected measurements. Over the past few years, many physicists have been trying to use this process to learn more about quantum states, as this...
Study unveils an antiferromagnetic metal phase in an electron-doped rare-earth nickelate
Researchers at Harvard University, the Lawrence Berkeley National Laboratory, Arizona State University, and other institutes in the United States have recently observed an antiferromagnetic metal phase in electron-doped NdNiO3 a material known to be a...
Researchers observe a bubble phase of composite fermions
Strong interactions between particles in physical systems can result in various highly correlated ground states. These states and the strong correlations underpinning them have been extensively explored in recent years.
A multi-turn energy recovery accelerator that achieves high beam power with lower power consumption
Particle accelerators are devices that use electromagnetic fields to speed up particles and collide them together or against a specific target. These devices are widely used by physicists to study particles, the forces that drive them and interactions between them.
Floquet band engineering in black phosphorus
Physicists have been trying to identify reliable strategies to manipulate quantum states in solid-state materials, cold atoms and other systems, as this could inform the development of new technologies. One of these strategies is Floquet engineering, which entails the...
An extension of FermiNet to discover quantum phase transitions
Architectures based on artificial neural networks (ANNs) have proved to be very helpful in research settings, as they can quickly analyze vast amounts of data and make accurate predictions. In 2020, Google's British AI subsidiary DeepMind used a new ANN architecture...
