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…
Hiding Ignorance Using High Dimensions
M. J. Kewming, S. Shrapnel, A. G. White +1
The absence of information -- entirely or partly -- is called ignorance. Naturally, one might ask if some ignorance of a whole system will imply some ignorance of its parts. Our cl…
Entropy production and fluctuation theorems in a continuously monitored optical cavity at zero temperature
M. J. Kewming, S. Shrapnel
Fluctuation theorems allow one to make generalised statements about the behaviour of thermodynamic quantities in systems that are driven far from thermal equilibrium. In this artic…
Physical grounds for causal perspectivalism
G. J. Milburn, S. Shrapnel, P. W. Evans
We ground the asymmetry of causal relations in the internal physical states of a special kind of open and irreversible physical system, a causal agent. A causal agent is an autonom…
