The Hamiltonian for an atom interacting with gravitational waves
Linda M. van Manen, André Grossardt
Building on the relativistic Hamiltonian of Sonnleitner and Barnett arXiv:1806.00234 and its post-Newtonian extensions by Schwartz and Giuilini arXiv:1908.06929, we investigate com…
Causal consistency requirements for gravity-induced entanglement in near-relativistic systems with internal energy
Linda M. van Manen, M. Kemal Döner, André Großardt
We reconsider a thought experiment that employs the entanglement of the gravitational field with position space quantum states as a means for faster-than-light signaling. We presen…
State Swapping via Semiclassical Gravity
Praveer K. Gollapudi, M. Kemal Döner, André Großardt
The prediction of non-local phenomena is a key attribute of quantum mechanics that distinguishes it from classical theories. It was recently suggested that state swapping is one su…
Nonlinear-ancilla aided quantum algorithm for nonlinear Schrödinger equations
André Großardt
We present an algorithm that uses a single ancilla qubit that can evolve nonlinearly, and show how to use it to efficiently solve generic nonlinear Schrödinger equations, including…
Self-gravitational dephasing of quasi-classical Stern-Gerlach trajectories
André Großardt
The nonlinear Schrödinger-Newton equation, a prospective semiclassical alternative to a quantized theory of gravity, predicts a gravitational self-force between the two trajectorie…
Coupling Quantum Matter and Gravity
Domenico Giulini, André Großardt, Philip K. Schwartz
In this contribution we deal with several issues one encounters when trying to couple quantum matter to classical gravitational fields. We start with a general background discussio…
