Quantum entanglement is a state in which particles are entwined with each other. In this entwined state, the properties of one particle influence the other, even when they aren’t physically close to each other. This phenomenon has often been observed in small quantum systems with only a few particles in them, where researchers can use it to store and process quantum information. Rice University professor Qimiao Si is interested in understanding and applying quantum entanglement to macroscopic systems with vast numbers of particles.
In a paper recently published in Nature Communications, Si described a method that could lead to not only better understanding of quantum entanglement in quantum materials but also more ready usage of quantum entanglement in macroscopic systems. His theory posits this can be done by coupling quantum materials to quantum light.
“In this theory, by placing matter in a small mirrored cavity and pushing it towards what is called the quantum critical point, we can then introduce photons and induce quantum entanglement in the photon-matter hybrid,” said Si, the Harry C. and Olga K. Wiess Professor of Physics and Astronomy and director of the Extreme Quantum Materials Alliance.
The planar Hall effect is a tabletop diagnostic tool for special quantum properties useful in basic research and technological applications. Or so it was thought, because careful calculation by Kobe University researchers clarifies the conditions under which this effect may also appear in classical materials. This makes the diagnostic more meaningful and enables more purposeful design.
In the hunt for materials with properties that are useful for quantum computing or spintronics, researchers have used the “planar Hall effect” as a tabletop diagnostic tool: The researchers send a current through a thin, flat sample and observe whether an electric voltage is produced in response to a magnetic field in the same plane as the sample.
If it is, the pattern of how the voltage responds to rotating the magnetic field in the plane of the sample tells researchers about the properties of the material.
The quantum internet is a network of quantum computers that will someday send, compute, and receive information encoded in quantum states. The quantum internet will not replace the modern or “classical” internet; instead, it will provide new functionalities such as quantum cryptography and quantum cloud computing.
While the full implications of the quantum internet won’t be known for some time, several applications have been theorized and some, like quantum key distribution, are already in use.
It’s unclear when a full-scale global quantum internet will be deployed, but researchers estimate that interstate quantum networks will be established within the United States in the next 10 to 15 years.

In the Big Bang Theory, the cosmic microwave background — microwave-range radiation that floats through the entire universe at a steady 2.7 Kelvin — is evidence that a hot explosion of plasma kicked off the creation of the universe. But according to a new paper, the microwave radiation came from early galaxies instead. Does this mean that the big bang theory is wrong? Let’s take a look.

Roman Yampolskiy has spent two decades being right about things people wished he wasn’t — and in this conversation, he’s not here to scare you, but to be precise. He makes the case that AI alignment isn’t merely unsolved but fundamentally under-defined: no agreed-upon values, no way to formalize them even if there were, and no mechanism for enforcing them on something smarter than its creators. His strongest argument isn’t a doom scenario, it’s that you cannot indefinitely control something smarter than you.
Nonlinear interactions between light and matter are at the heart of some of the most powerful tools in modern optics, but pushing these processes to their limits has long been hampered by a fundamental constraint: the stronger you make the laser, the more likely it is to destroy whatever it illuminates.
Through new experiments detailed in Nature, Jian Wu and colleagues at East China Normal University in Shanghai have found a way around this problem, by exploiting the quantum nature of light itself.
