Quantum entanglement can act as the thread from which spacetime is woven, a claim grounded in theoretical work that links quantum information to geometric concepts. Mark Van Raamsdonk of University of British Columbia argued that varying patterns of entanglement between quantum degrees of freedom change connectivity in holographic models, showing that reducing entanglement can split an emergent spacetime into disconnected pieces. Juan Maldacena of Institute for Advanced Study together with Leonard Susskind of Stanford University proposed that entangled pairs may be connected by nontraversable wormhole geometries, an idea known as ER equals EPR that reframes puzzles about locality and information flow in gravitational systems.
Entanglement and geometry
A concrete bridge between entanglement and geometry appears in the Ryu Takayanagi proposal, which identifies entanglement entropy of a boundary quantum state with the area of a minimal surface in a dual bulk geometry. This relation, developed within the AdS CFT correspondence, makes the influence of entanglement on spatial geometry quantitative and has been widely cited by researchers working on quantum gravity and quantum information. The mechanism is not a claim that ordinary laboratory entanglement reshapes everyday space but rather that, in certain quantum gravitational frameworks, geometric notions emerge from patterns of correlation among microscopic degrees of freedom.
Consequences and experiments
The consequences touch central problems such as the black hole information paradox and the nature of emergent spacetime. If geometry arises from entanglement, then resolving how information escapes evaporating black holes may require understanding how entanglement structure encodes bulk geometry. These ideas have reshaped research agendas at institutions across the world, from the Institute for Advanced Study to university departments and research centers that combine expertise in quantum information and gravity. Experimental tests remain indirect: condensed matter systems and engineered quantum simulators can probe entanglement structure and test aspects of the correspondence, but direct access to Planck scale geometry is beyond current technology.
Impact and uniqueness
What makes this phenomenon unique is the synthesis of two previously separate perspectives, viewing spacetime as an emergent, information-theoretic construct rather than a fixed stage. This reconnection of geometry and quantum mechanics has cultural effects within the scientific community, encouraging interdisciplinary collaboration between theorists and experimentalists and guiding funding and training priorities in territories where fundamental physics intersects with quantum technology. The result is a fertile, evidence-informed research program that links abstract mathematical results with concrete questions about the physical world.
