The effect of non-selective measurement on the parameter estimation within spin-spin model
Ali Raza Mirza, Jim Al-Khalili
We investigate the role of non-selective measurement on the estimation of system-environment parameters. Projective measurement is the popular method of initial state preparation w…

The role of initial system-environment correlations in the accuracies of parameters within spin-spin model
Ali Raza Mirza, Jim Al-Khalili
We investigate the effect of initial system-environment correlations to improve the estimation of environment parameters. By employing various physical situations of interest, we p…

The Decoherent Arrow of Time and the Entanglement Past Hypothesis
Jim Al-Khalili, Eddy Keming Chen
If an asymmetry in time does not arise from the fundamental dynamical laws of physics, it may be found in special boundary conditions. The argument normally goes that since thermod…
