A new study in Physical Review Letters (PRL) introduces the concept of pseudomagic quantum states, which appear to have high stabilizerness (or complexity) and can move us closer to achieving quantum supremacy.
Faithful transfer of quantum states between different parts of a single complex quantum circuit will become more and more important as quantum computing devices grow in size. Here, the authors transfer single-qubit excitations, two-qubit entangled states, and two excitations across a 6 × 6 superconducting qubit device.
Quantum computers have the potential to solve complex problems in human health, drug discovery, and artificial intelligence millions of times faster than some of the world’s fastest supercomputers. A network of quantum computers could advance these discoveries even faster. But before that can happen, the computer industry will need a reliable way to string together billions of qubits—or quantum bits—with atomic precision.
The Korea Research Institute of Standards and Science (KRISS) has developed a novel quantum sensor technology that allows the measurement of perturbations in the infrared region with visible light by leveraging the phenomenon of quantum entanglement. This will enable low-cost, high-performance IR optical measurement, which previously accompanied limitations in delivering quality results.
An exploration of various ways of looking at time and how General Relativity and Quantum Mechanics views it differently and the ultimately question, what exactly is time?

Similar to how a radio antenna plucks a broadcast from the air and concentrates the energy into a song, individual atoms can collect and concentrate the energy of light into a strong, localized signal that researchers can use to study the fundamental building blocks of matter.

Quantum field theory reveals potential flaws in models predicting numerous primordial black holes, suggesting fewer exist, which may impact theories of dark matter and the universe’s structure.
Researchers have applied the well-understood and highly verified quantum field theory, usually applied to the study of the very small, to a new target, the early universe. Their exploration led to the conclusion that there ought to be far fewer miniature black holes than most models suggest, though observations to confirm this should soon be possible. The specific kind of black hole in question could be a contender for dark matter.
The study, which was published recently in Physical Review Letters, was conducted by researchers at the Research Center for the Early Universe (RESCEU) and Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU, WPI) at the University of Tokyo.
Researchers from the Photonics Research Laboratory (PRL)-iTEAM at the Universitat Politècnica de València, in collaboration with iPRONICS, have developed a groundbreaking photonic chip. This chip is the world’s first to be universal, programmable, and multifunctional, making it a significant advancement for the telecommunications industry, data centers, and AI computing infrastructures. It is poised to enhance a variety of applications including 5G communications, quantum computing, data centers, artificial intelligence, satellites, drones, and autonomous vehicles.
The development of this revolutionary chip is the main result of the European project UMWP-Chip, led by researcher José Capmany and funded by an ERC Advanced Grant from the European Research Council. The work has been published in the Nature Communications journal.
Principles behind gravity-mediated entanglement were experimentally demonstrated in a simulation using photons, providing new insights into the nature of gravity.
Researchers are making significant progress in the field of quantum gravity, aiming to reconcile Einstein’s theory of gravity with quantum mechanics. Recent experiments demonstrate the principles of gravity-mediated entanglement using photons, a breakthrough in testing theories like string theory and loop quantum gravity. These experiments could transform our understanding of the universe and support future theoretical frameworks.
