Spacetime quantum mechanics for bosonic and fermionic systems
N. L. Diaz, R. Rossignoli
We provide a Hilbert space approach to quantum mechanics where space and time are treated on an equal footing. Our approach replaces the standard dependence on an external classica…

Parallel-in-time quantum simulation via Page and Wootters quantum time
N. L. Diaz, Paolo Braccia, Martin Larocca +3
In the past few decades, researchers have created a veritable zoo of quantum algorithms by drawing inspiration from classical computing, information theory, and even from physical…

Path Integrals from Spacetime Quantum Actions
N. L. Diaz, J. M. Matera, R. Rossignoli
The possibility of extending the canonical formulation of quantum mechanics (QM) to a space-time symmetric form has recently attracted wide interest. In this context, a recent prop…
