Gravitational redshift induces quantum interference
David Edward Bruschi, Andreas W. Schell
We use quantum field theory in curved spacetime to show that gravitational redshift induces a unitary transformation on the quantum state of propagating photons. This occurs for re…
Spacetime effects on wavepackets of coherent light
David Edward Bruschi, Symeon Chatzinotas, Frank K. Wilhelm +1
We investigate the interplay between gravity and the quantum coherence present in the state of a pulse of light propagating in curved spacetime. We first introduce an operational w…
Factorizing time evolution into elementary steps
David Edward Bruschi
We propose an approach to factorize the time-evolution operator of a quantum system through a (finite) sequence of elementary operations that are time-ordered. Our proposal borrows…
