More “proof” for a holographic universe?
Very interesting article by Matt Swayne published in Quantum Insider today….
“A new study published in Annals of Physics proposes that quantum information — encoded in entanglement information entropy — directly influences the curvature of spacetime, suggesting gravity may emerge from quantum information itself. The study proposes that quantum information, encoded in entanglement entropy, directly shapes the fabric of spacetime, offering a fresh path toward unifying gravity and quantum mechanics.
“Published in Annals of Physics, the paper presents a reformulation of Einstein’s field equations, arguing that gravity is not just a response to mass and energy, but also to the information structure of quantum fields. This shift, if validated, would mark a fundamental transformation in how physicists understand both gravity and quantum computing.
“In conventional general relativity, the curvature of spacetime is determined by the energy and momentum of matter and radiation. The new framework adds another driver: the quantum information shared between fields. This extra term modifies Einstein’s equations and offers an explanation for some of gravity’s more elusive behaviors, including potential corrections to Newton’s gravitational constant.
“For researchers working on quantum computing, the study reinforces the idea that entanglement isn’t just a computational resource — it might be a structural element of the universe. The research implies that as quantum computing systems manipulate entanglement, they’re tapping into the same mechanisms that influence the shape of spacetime.
“This duality between geometry and information, the study argues, has far-reaching consequences. In particular, it suggests that gravity could emerge from entanglement at the quantum level — a view aligned with ongoing efforts in quantum gravity, including holographic theories.
“Ultimately, the study does not claim to resolve quantum gravity, but it does reframe the problem. By showing how entanglement entropy can be mathematically folded into Einstein’s equations, it opens a promising path that links spacetime to information — a concept familiar to quantum computer scientists and physicists alike.
“Future research directions would require a broader program of inquiry to follow up on the groundwork laid by this study. The author suggests that emerging quantum experiments, including precision measurements of gravity at short distances and black hole imaging, may eventually provide indirect support for the theory.”
There is a field of study that is rapidly becoming more and more important that you should watch carefully in the next couple of years: Quantum Information Science. Here’s how the National Institute of Standards and Technology (NIST) describes it….
“Quantum information science marries two of the 20th century’s most important scientific developments: quantum physics and information theory. Quantum physics describes the universe at its smallest and most fundamental scales — think atoms and molecules; light and energy. Information theory underpins the workings of computers and the internet — technologies that have transformed our world. Together, they herald a new technological revolution that could supercharge physics, materials science, chemistry, biomedicine, encryption, communications and many other areas.
Quantum information science involves using the smallest bits of matter and energy — electrons inside an atom, tiny circuits, massless particles of light — to store, carry and process information. Scientists around the world are developing quantum computers, a new kind of machine that can, in theory, simulate the fundamentally quantum nature of matter and tackle certain currently unsolvable problems. Other focus areas of quantum information science include quantum sensors for ultra-high-precision measurements and quantum networks that could link devices across cities, nations and ultimately the globe.”
