Operational models of temperature superpositions
Carolyn E. Wood, Harshit Verma, Fabio Costa +1
A quantum system and a thermal bath can reach thermal equilibrium through an interaction, whereupon the system acquires the same temperature as the bath. But how does a delocalised…
Constraining the number of fundamental quantum degrees of freedom using gravity
Harshit Verma, Magdalena Zych, Fabio Costa
We consider the effect of gravity on extended quantum systems (EQS) in the low energy regime. We model the gravitational effect due to a nearby source mass as a redshift in the int…
Background Independence and Quantum Causal Structure
Lachlan Parker, Fabio Costa
One of the key ways in which quantum mechanics differs from relativity is that it requires a fixed background reference frame for spacetime. In fact, this appears to be one of the…
Experimental characterisation of a non-Markovian quantum process
K. Goswami, C. Giarmatzi, C. Monterola +3
Every quantum system is coupled to an environment. Such system-environment interaction leads to temporal correlation between quantum operations at different times, resulting in non…
Preprocessing operations and the reverse compression
Matheus Capela, Fabio Costa
The task of compression of data -- as stated by the source coding theorem -- is one of the cornerstones of information theory. Data compression usually exploits statistical redunda…
