A team of Chinese scientists introduced a quantum communication technique that they say could help secure Web 3.0 against the formidable threat of quantum computing.

Their approach, called Long-Distance Free-Space Quantum Secure Direct Communication (LF QSDC), promises to improve data security by enabling encrypted direct messaging without the need for key exchange, a method traditionally vulnerable to quantum attacks.

They add the approach not only enhances security but also aligns with the decentralized ethos of Web 3.0, offering a robust defense in the rapidly evolving digital landscape.

A team of researchers have claimed to have recently detected a telltale signature of stimulated Hawking radiation from a post-merger black hole. If the researchers’ analysis of gravitational wave data is correct, then they may have found the first evidence of Planck-scale quantum structure at the event horizon of a black hole (quantum horizons). The key signature of a non-classical horizon is an echo signal in the gravitational waves that are detected after the primary merger event of a binary black hole system. The evidence is tentative, but nevertheless tantalizing. Such research is pivotal to advancing our understanding of quantum effects in strong gravity, where novel aspects of the theory of quantum gravity may be hard at work, as exemplified in the remarkable research The Origin of Mass and the Nature of Gravity, in which physicist Nassim Haramein with his colleagues Dr. Olivier Alirol and Dr. Cyprien Guermonprez have demonstrated that the mass-energy of Hawking radiation from a baryonic-scale mini black hole exactly produces the observed rest-mass energy of the proton, demonstrating that the proton rest-mass is the result of quantum vacuum fluctuations of the electromagnetic field in strongly curved spacetime. The analysis of gravitational wave data for an echo signature, the smoking gun of quantum horizons and Hawking radiation, in conjunction with recent observation of Unruh radiation from accelerating electrons, is a significant confirmation of quantum gravitational predictions of unified physics, which we see in solutions like that of Haramein et al. are the solution to understanding the source of mass and force originating from quantum vacuum fluctuations in curved spacetime. It is a major advancement because Unruh-Hawking radiation can no longer be said to be “only theoretical”

In this article, realistic quantitative estimation of dark matter and dark energy considered as informational phenomena have been computed, thereby explaining certain anomalies and effects within the universe. Moreover, by the same conceptual approach, the cosmological constant problem has been reduced by almost 120 orders of magnitude in the prediction of the vacuum energy from a quantum point of view. We argue that dark matter is an informational field with finite and quantifiable negative mass, distinct from the conventional fields of matter of quantum field theory and associated with the number of bits of information in the observable universe, while dark energy is negative energy, calculated as the energy associated with dark matter.

Scientists are a step closer to unraveling the mysterious forces of the universe after working out how to measure gravity on a microscopic level.

Experts have never fully understood how the force that was discovered by Isaac Newton works in the tiny quantum world. Even Einstein was baffled by quantum gravity and, in his theory of general relativity, said there is no realistic experiment that could show a quantum version of gravity.

But now physicists at the University of Southampton, working with scientists in Europe, have successfully detected a weak gravitational pull on a tiny particle using a new technique.

Watch some of the biggest names in physics debate the mysteries of the quantum and its future, including Roger Penrose, Sabine Hossenfelder, Avshalom Elitzur, Michio Kaku, Suchitra Sebastian, Priya Natarajan, Joscha Bach, Erik Verlinde, Hilary Lawson and Bjørn Ekeberg.

From string theory to quantum gravity and quantum computers, the quantum discourse is all the buzz in physics and beyond. But what is possible and what mere fantasy? Can we bring together relativity and quantum mechanics? Will we ever find a unified theory to explain our universe?

A proposed recipe for quantum error correction removes the need for time-consuming measurements of qubits, replacing them with copying and feedback steps instead.

Researchers have characterized the thermodynamic properties of a model that uses cold atoms to simulate condensed-matter phenomena.

Scientists achieve breakthrough in quantum optics with photon detector-based method, paving the way for improved quantum computing.

Scientists at Paderborn University have used a new method to determine the characteristics of optical, i.e. light-based, quantum states. For the first time, they are using certain photon detectors — devices that can detect individual light particles — for so-called homodyne detection. The ability to characterize optical quantum states makes the method an essential tool for quantum information processing. Precise knowledge of the characteristics is important for use in quantum computers, for example. The results have now been published in the specialist journal Optica Quantum.
