Mutual Information Across Quantum Reference Frame Perspectives
Leonardo Valente, Carla Ferradini, Flaminia Giacomini +1
In quantum information theory, standard notions typically presuppose a fixed partition of the world into subsystems, encoded in a tensor product structure of the Hilbert space. Yet…
Reduced Quantum-Reference-Frame Channels for Open Quantum Systems
Paolo Luppi, Viktoria Kabel, Flaminia Giacomini +1
When reference frames are treated quantum mechanically, the subsystem structure of quantum systems is no longer absolute, but depends on the choice of the quantum reference frame (…
Accessibility of Global Properties from Internal Quantum Reference Frame Perspectives
Anne-Catherine de la Hamette, Viktoria Kabel, Časlav Brukner
A fundamental question in the field of quantum reference frames concerns what global properties of a system can be determined by observers operating entirely from within that syste…
Identification is Pointless: Quantum Coordinates, Localisation of Events, and the Quantum Hole Argument
Viktoria Kabel, Anne-Catherine de la Hamette, Luca Apadula +4
The study of quantum reference frames (QRFs) is motivated by the idea of taking into account the quantum properties of the reference frames used, explicitly or implicitly, in our d…
Indefinite causal order and quantum coordinates
Anne-Catherine de la Hamette, Viktoria Kabel, Marios Christodoulou +1
Classically the causal order of two timelike separated events A and B is fixed -- either A before B or B before A. This is no longer true in quantum theory, where it is possible to…
Quantum conformal symmetries for spacetimes in superposition
Viktoria Kabel, Anne-Catherine de la Hamette, Esteban Castro-Ruiz +1
Without a complete theory of quantum gravity, the question of how quantum fields and quantum particles behave in a superposition of spacetimes seems beyond the reach of theoretical…
Quantum reference frames for an indefinite metric
Anne-Catherine de la Hamette, Viktoria Kabel, Esteban Castro-Ruiz +1
The current theories of quantum physics and general relativity on their own do not allow us to study situations in which the gravitational source is quantum. Here, we propose a str…
