Exponential improvement for quantum cooling through finite-memory effects
Philip Taranto, Faraj Bakhshinezhad, Philipp Schüttelkopf +2
Practical implementations of quantum technologies require preparation of states with a high degree of purity---or, in thermodynamic terms, very low temperatures. Given finite resou…
Memory Effects in Quantum Processes
Philip Taranto
Understanding temporal processes and their correlations in time is of paramount importance for the development of near-term technologies that operate under realistic conditions. Ca…
When is a non-Markovian quantum process classical?
Simon Milz, Dario Egloff, Philip Taranto +4
More than a century after the inception of quantum theory, the question of which traits and phenomena are fundamentally quantum remains under debate. Here we give an answer to this…
The Structure of Quantum Stochastic Processes with Finite Markov Order
Philip Taranto, Simon Milz, Felix A. Pollock +1
Non-Markovian quantum processes exhibit different memory effects when measured in different ways; an unambiguous characterization of memory length requires accounting for the seque…
Quantum Markov Order
Philip Taranto, Felix A. Pollock, Simon Milz +2
We formally extend the notion of Markov order to open quantum processes by accounting for the instruments used to probe the system of interest at different times. Our description r…
