Green noise or green value? Measuring the price effects of environmental certification in commercial buildings [PDF]

open access: yes, 2008
This paper investigates the price effects of environmental certification on commercial real estate assets. It is argued that there are likely to be three main drivers of price differences between certified and non-certified buildings.

Optimal randomness certification in the quantum steering and prepare-and-measure scenarios [PDF]

open access: yes, 2015
Quantum mechanics predicts the existence of intrinsically random processes. Contrary to classical randomness, this lack of predictability can not be attributed to ignorance or lack of control.

Certifying classes of d-outcome measurements with quantum steering

open access: yesNew Journal of Physics
Device-independent (DI) certification schemes are based on minimal assumptions about the quantum system under study, which makes the most desirable among certification schemes. However, they are often the most challenging to implement. In order to reduce
