Perimeter Research Links 3D Gravity to 2D Quantum Surfaces

Researchers at Perimeter Institute are applying techniques from quantum cryptography to reveal surprising connections between gravity and entanglement, offering new insight into one of physics’ most enduring challenges. The work centers on the AdS/CFT correspondence, where a three-dimensional gravitational spacetime, or Anti-de Sitter space, can be described by a two-dimensional quantum field theory, functioning like a “3D hologram of a 2D surface.” Alex May, Murray Gell-Mann Chair in Theoretical Physics at Perimeter Institute, explains that “entanglement is one of the ingredients that makes this correspondence work.” Perimeter Institute, a research hub devoted to theoretical physics, believes understanding how gravity and quantum mechanics fit together is crucial, as unifying them remains a primary goal in modern physics.

The Institute’s research, funded in part by the Governments of Ontario and Canada, aims to catalyze innovation through fundamental scientific advancements, believing that theoretical physics will drive future technologies. This exploration of AdS/CFT is not simply an academic exercise, but a step towards a more complete understanding of the universe at its most fundamental level. Quantum cryptography, a field dedicated to secure communication, is now providing unexpected insights into the relationship between gravity and quantum mechanics. Researchers are applying its tools to explore the perplexing AdS/CFT correspondence, a theoretical framework where a gravitational spacetime and a quantum field theory describe the same physical reality. Here, a special kind of gravitational spacetime (Anti-de Sitter space or AdS) and a specific kind of quantum field theory (conformal field theory or CFT) are able to describe the same physics – even though the spacetime has one more dimension than the field theory, as if it were a 3D hologram of a 2D surface.
