Research on Quantum wormhole stability

This research explores how quantum wormholes — theoretical tunnels through spacetime — could remain stable. Since such wormholes need exotic matter (with negative energy), the paper looks at how quantum effects like the Casimir effect and quantum energy inequalities might help stabilize them. It also considers the challenges, like quantum backreaction (where quantum fields affect spacetime) and energy condition violations. The paper uses semiclassical gravity to combine general relativity with quantum theory, aiming to create a theoretical framework for stable, traversable wormholes.
