Decoherence without the state: A causal quantum Darwinist approach
Nick Ormrod, Tein van der Lugt, Yìlè Yīng +1
The consistent histories formalism can be used to describe histories comprised of events across many systems, times, and places, plausibly rich enough to describe our experiences o…

Unitary causal decompositions: a combinatorial characterisation via lattice theory
Tein van der Lugt, Robin Lorenz
If a unitary transformation has a decomposition into a quantum circuit with no directed path from input to output , then does not influence through the overall unita…

An order-theoretic circuit syntax and characterisation of the concept lattice
Tein van der Lugt
We take an order-theoretic approach to circuit (string diagram) syntax, treating a circuit as a partial order with additional input-output structure. We define morphisms between ci…
