Physicists are developing a theory that connects quantum entanglement and a quantum property called "magic" to the emergence of space-time and gravity. While previous work suggested that quantum entanglement creates the fabric of space-time, researchers now propose that magic, a measure of how difficult quantum states are to simulate classically, may be responsible for generating gravitational forces. This represents an effort to reconcile Einstein's general relativity with quantum mechanics by showing how space-time geometry emerges from quantum information properties.
Why it matters
This research could lead to a unified theory of quantum gravity, resolving one of the biggest outstanding problems in theoretical physics. Understanding how space-time emerges from quantum properties may also provide insights into black holes, the early universe, and the fundamental nature of reality.
In 1973, John Archibald Wheeler described the relationship between space and matter in two sentences: “Space acts on matter, telling it how to move. In turn, matter reacts back on space, telling it how to curve.” Wheeler’s words serve as a pithy encapsulation of general relativity, Albert Einstein’s theory of gravity. Wheeler’s sentences also lay out a challenge that theorists face today: When…
