Scientists have created an ultra-thin light source that emits pairs of polarization-entangled photons. These specially correlated photons hold promise for future quantum technologies, including ultra-secure communication, powerful computation, and high-precision measurements. This light source is particularly small, pure, efficient, and versatile.
Entangled photons share a unique connection. By measuring one photon’s properties, scientists can instantly determine the properties of its entangled partner, regardless of distance. This phenomenon has the potential to revolutionize fields like communication, computation and metrology.
This Deep Dive AI podcast discusses my book The Physics of Time: D-Theory of Time & Temporal Mechanics, an insightful exploration into one of the most profound mysteries of existence: the nature of time. As part of the Science and Philosophy of Information series, this book presents a radical reinterpretation of time grounded in modern physics and digital philosophy. It questions whether time is a fundamental aspect of reality or an emergent property of consciousness and information processing. Drawing on quantum physics, cosmology, and consciousness studies, this work invites readers (and listeners) to reimagine time not as a linear, absolute entity, but as a dynamic, editable dimension intertwined with the fabric of reality itself. It challenges traditional views, blending scientific inquiry with metaphysical insights, aimed at both the curious mind and the philosophical seeker.
In this episode, we dive deep into The Physics of Time: D-Theory of Time & Temporal Mechanics by futurist-philosopher Alex M. Vikoulov. Explore the profound questions at the intersection of consciousness, quantum and digital physics, and the true nature of time. Is time fundamental or emergent? Can we travel through it? What is Digital Presentism?
The Physics of Time: D-Theory of Time & Temporal Mechanics by Alex M. Vikoulov is an insightful exploration into one of the most profound mysteries of existence: the nature of time. As part of the Science and Philosophy of Information series, this book presents a radical reinterpretation of time grounded in modern physics and digital philosophy. It questions whether time is a fundamental aspect of reality or an emergent property of consciousness and information processing.
The book introduces the D-Theory of Time, or Digital Presentism, which suggests that all moments exist as discrete, informational states, and that our perception of time’s flow is a mental construct. Vikoulov explores theoretical models of time travel, the feasibility of manipulating time, and the concept of the Temporal Singularity, a proposed point where temporal mechanics may reach a transformative threshold.
Quantum computers promise to speed calculations dramatically in some key areas such as computational chemistry and high-speed networking. But they’re so different from today’s computers that scientists need to figure out the best ways to feed them information to take full advantage. The data must be packed in new ways, customized for quantum treatment.
Scientists have achieved a major milestone in the quest to understand high-temperature superconductivity in hydrogen-rich materials. Using electron tunneling spectroscopy under high pressure, the international research team led by the Max Planck Institute for Chemistry has measured the superconducting gap of H3S—the material that set the high-pressure superconductivity record in 2015 and serves as the parent compound for subsequent high-temperature superconducting hydrides.
The findings, published this week in Nature, provide the first direct microscopic evidence of superconductivity in hydrogen-rich materials and an important step toward its scientific understanding.
Superconductors are materials that can carry electrical current without resistance, making them invaluable for technologies such as energy transmission and storage, magnetic levitation, and quantum computing.
Quantum messages sent across a 254-km telecom network in Germany represent the first known report of coherent quantum communications using existing commercial telecommunication infrastructure.
The demonstration, reported in Nature this week, suggests that quantum communications can be achieved in real-world conditions.
Quantum networks have the potential to enable secure communications, such as a quantum internet; quantum key distribution is one example of a theoretically secure communication technique.
An exact expression for a key process needed in many quantum technologies has been derived by a RIKEN mathematical physicist and a collaborator. This could help to guide advances in quantum technologies.
Entanglement is the mysterious phenomenon whereby two or more particles become so closely interconnected that, no matter how great the distance between them, they exhibit quantum correlations that far exceed the mutual relations achievable in classical systems.
In the intricate world of quantum physics, where particles interact in ways that seem to defy the standard rules of space and time, lies a profound mystery that continues to captivate scientists: the nature of deconfined quantum critical points (DQCPs). These elusive critical phenomena break away from the conventional framework of physics, offering a fascinating glimpse into a realm where quantum matter behaves in ways that challenge our classical understanding of the fundamental forces shaping the universe.
A recent study, led by Professor Zi Yang Meng and co-authored by his Ph.D. student Menghan Song of HKU Department of Physics, in collaboration with researchers from the Chinese University of Hong Kong, Yale University, University of California, Santa Barbara, Ruhr-University Bochum and TU Dresden, has unraveled some of the secrets concealed within the entangled web of quantum systems.
Their findings, recently published in Science Advances, push the boundaries of modern physics and offer a fresh perspective on how quantum matter operates at these enigmatic junctures. The study not only deepens our understanding of quantum mechanics but also paves the way for future discoveries that could revolutionize technology, materials science, and even our understanding of the cosmos.
In new research published in Nature, Weizmann Institute scientists introduce a powerful tool to explore quantum phenomena—the cryogenic Quantum Twisting Microscope (QTM).
Using this pioneering instrument, researchers have observed—for the first time—the interactions between electrons and an exotic atomic vibration in twisted sheets of graphene, called a phason. These findings shed new light on the mysterious superconductivity and strange metallicity that emerge when graphene sheets are rotated to the magic angle.
The fundamental properties of materials depend critically on their underlying particles—the flow of electrons governs electrical resistance, and atomic lattice vibrations, termed phonons, drive heat conductivity. However, when electrons and phonons are coupled, remarkable new phenomena can emerge.
