On unorthodox qubits, with an application to the closed timelike curve problem
Samuel Kuypers
In orthodox quantum theory the observables of spacelike separated quantum systems commute. I shall call this the commutation constraint. It severely limits quantum theory's explana…

Everettian relative states in the Heisenberg picture
Samuel Kuypers, David Deutsch
Everett's relative-state construction in quantum theory has never been satisfactorily expressed in the Heisenberg picture. What one might have expected to be a straightforward proc…

Visualizing topological transport
Mariya A. Lizunova, Samuel Kuypers, Bernet Meijer +2
We present a mathematically simple procedure for explaining and visualizing the dynamics of quantized transport in topological insulators. The procedure serves to illustrate and cl…
