Verification of joint measurability using phase-space quasiprobability distributions
Saleh Rahimi-Keshari, Mohammad Mehboudi, Dario De Santis +2
Measurement incompatibility is a distinguishing property of quantum physics and an essential resource for many quantum information processing tasks. We introduce an approach to ver…
Geometry of work fluctuations versus efficiency in microscopic thermal machines
Harry J. D. Miller, Mohammad Mehboudi
When engineering microscopic machines, increasing efficiency can often come at a price of reduced reliability due to the impact of stochastic fluctuations. Here we develop a genera…
Linear response theory for quantum Gaussian processes
Mohammad Mehboudi, Juan. M. R. Parrondo, Antonio Acin
Fluctuation dissipation theorems connect the linear response of a physical system to a perturbation to the steady-state correlation functions. Until now, most of these theorems hav…
Thermometry in the quantum regime: Recent theoretical progress
Mohammad Mehboudi, Anna Sanpera, Luis A. Correa
Controlling and measuring the temperature in different devices and platforms that operate in the quantum regime is, without any doubt, essential for any potential application. In t…
Using polarons for sub-nK quantum non-demolition thermometry in a Bose-Einstein condensate
Mohammad Mehboudi, Aniello Lampo, Christos Charalambous +3
We introduce a novel minimally-disturbing method for sub-nK thermometry in a Bose-Einstein condensate (BEC). Our technique is based on the Bose-polaron model; namely, an impurity e…
Dynamically induced heat rectification in quantum systems
Andreu Riera-Campeny, Mohammad Mehboudi, Marisa Pons +1
Heat rectifiers are systems that conduct heat asymmetrically for forward and reversed temperature gradients. Here, we present an analytical study of heat rectification in linear qu…
