Emergent Geometry from Quantum Probability
Shadi Ali Ahmad, Marc S. Klinger
Carrying the insights of conditional probability to the quantum realm is notoriously difficult due to the non-commutative nature of quantum observables. Nevertheless, conditional e…
Relational Quantum Geometry
Shadi Ali Ahmad, Wissam Chemissany, Marc S. Klinger +1
A common feature of the extended phase space of gauge theory, the crossed product of quantum theory, and quantum reference frames (QRFs) is the adjoining of degrees of freedom foll…
Semifinite von Neumann algebras in gauge theory and gravity
Shadi Ali Ahmad, Marc S. Klinger, Simon Lin
von Neumann algebras have been playing an increasingly important role in the context of gauge theories and gravity. The crossed product presents a natural method for implementing c…
Quantum Reference Frames from Top-Down Crossed Products
Shadi Ali Ahmad, Wissam Chemissany, Marc S. Klinger +1
All physical observations are made relative to a reference frame, which is a system in its own right. If the system of interest admits a group symmetry, the reference frame observi…
