Quantum Foundations

A research area focused on time symmetry, global consistency, and emergent structure in quantum theory.

Research Area Description

This research investigates foundational questions at the intersection of quantum mechanics, time, and spacetime structure.

The central focus is the role of global consistency constraints, particularly two-boundary (time-symmetric) conditions, in shaping observable physics. Rather than treating time evolution and dynamics as fundamental, the work explores models in which classical temporality, probability flow, and geometry arise as emergent features of a globally constrained quantum state.

Key Themes

  • Time-symmetric and two-boundary quantum formalisms

  • Emergent arrows of time from entropy and consistency

  • Entanglement-induced geometry and spacetime reconstruction

  • Consistent and decoherent histories

  • Information-theoretic and geometric approaches to quantum foundations

Active Research Programmes

Research in Quantum Foundations is organised into three closely related programmes:

  • ChronaQ, a theoretical framework for emergent time, geometry, and local physical law

  • ψ-Mathematics (psi-m), a mathematical programme for projection-based quantum structure

  • Signed Probability (SP), a probabilistic framework extending classical probability beyond non-negativity

Full descriptions of each programme are provided on the Programmes page.
