Quantum Weirdness Caused by Interacting Parallel Worlds

A new theory of quantum mechanics presumes not only that parallel worlds exist, but also that their mutual interaction is what gives rise to all quantum effects observed in nature. The theory, first published by Professor Bill Poirier four years ago, has recently attracted attention from the foundational physics community, leading to an invited Commentary […]

Scientists Propose Existence of Parallel Worlds

In a newly published study, physicists propose that parallel universes really exist and that they interact and influence one another by a subtle force of repulsion. Griffith University academics are challenging the foundations of quantum science with a radical new theory based on the existence of, and interactions between, parallel universes. In a paper published […]

Yale Engineers Develop a Chip Scale Device That Uses Interaction Free Measurement

Engineers at the Yale School of Engineering & Applied Science have developed a chip-scale device that uses the wave-particle duality of single photons to sense the presence of an object without interacting with it – a technique known as “interaction-free measurement.” “Our device uses silicon photonics to create interaction-free measurement on an integrated chip—something previously […]

Researchers Develop a Way to Probe the Kind of Matter that Dominated the Universe Immediately After the Big Bang

Nuclear scientists at the U.S. Department of Energy’s Lawrence Berkeley National Lab have made the most precise extraction to date of a key property of the quark-gluon plasma, which reveals the microscopic structure of this almost perfect liquid. By combining data from two high-energy accelerators, nuclear scientists have refined the measurement of a remarkable property […]

Artificial Atom Could Help Answer Fundamental Questions about the Physics of Matter

By crystallizing light, Princeton University researchers have begun to address questions about the fundamental study of matter. The researchers are not shining light through crystal – they are transforming light into crystal. As part of an effort to develop exotic materials such as room-temperature superconductors, the researchers have locked together photons, the basic element of […]

Superabsorption of Light Via Quantum Engineering

Research from the University of Oxford establishes that superabsorption can be achieved and sustained in certain simple nanostructures, by trapping the system in a highly excited state while extracting energy into a non-radiative channel. The effect offers the prospect of a new class of quantum nanotechnology, capable of absorbing light many times faster than is […]

A Path Toward Better Quantum Computers and Nanoscale Sensors

Engineers at the University of Chicago have used a diamond defect called a nitrogen vacancy center to clear a path toward better quantum computers and nanoscale sensors. By carefully controlling the position of an atomic-scale diamond defect within a volume smaller than what some viruses would fill, researchers have cleared a path toward better quantum […]

Weizmann Physicists Measure Magnetic Interactions between Single Electrons

By using a technique that binds two electrons together so that their spins point in opposite directions, physicists at the Weizmann Institute of Science were able to measure magnetic interactions between single electrons. Imagine trying to measure a tennis ball that bounces wildly, every time to a distance a million times its own size. The […]
