Efficiently Cooling Quantum Systems with Finite Resources: Insights from Thermodynamic Geometry
Philip Taranto, Patryk Lipka-Bartosik, Nayeli A. Rodríguez-Briones +4
Landauer's limit on heat dissipation during information erasure is critical as devices shrink, requiring optimal pure-state preparation to minimise errors. However, Nernst's third…
Characterising the Hierarchy of Multi-time Quantum Processes with Classical Memory
Philip Taranto, Marco Túlio Quintino, Mio Murao +1
Memory is the fundamental form of temporal complexity: when present but uncontrollable, it manifests as non-Markovian noise; conversely, if controllable, memory can be a powerful r…
Connecting Commutativity and Classicality for Multi-Time Quantum Processes
Fattah Sakuldee, Philip Taranto, Simon Milz
Understanding the demarcation line between classical and quantum is an important issue in modern physics. The development of such an understanding requires a clear picture of the v…
Hidden Quantum Memory: Is Memory There When Somebody Looks?
Philip Taranto, Thomas J. Elliott, Simon Milz
In classical physics, memoryless dynamics and Markovian statistics are one and the same. This is not true for quantum dynamics, first and foremost because quantum measurements are…
Landauer vs. Nernst: What is the True Cost of Cooling a Quantum System?
Philip Taranto, Faraj Bakhshinezhad, Andreas Bluhm +9
Thermodynamics connects our knowledge of the world to our capability to manipulate and thus to control it. This crucial role of control is exemplified by the third law of thermodyn…
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…
Experimental Demonstration of Instrument-specific Quantum Memory Effects and Non-Markovian Process Recovery for Common-Cause Processes
Yu Guo, Philip Taranto, Bi-Heng Liu +4
The duration, strength and structure of memory effects are crucial properties of physical evolution. Due to the invasive nature of quantum measurement, such properties must be defi…
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…
Non-Markovian Memory Strength Bounds Quantum Process Recoverability
Philip Taranto, Felix A. Pollock, Kavan Modi
Generic non-Markovian quantum processes have infinitely long memory, implying an exact description that grows exponentially in complexity with observation time. Here, we present a…
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…
Emergence of a fluctuation relation for heat in nonequilibrium Landauer processes
Philip Taranto, Kavan Modi, Felix A. Pollock
In a generalized framework for the Landauer erasure protocol, we study bounds on the heat dissipated in typical nonequilibrium quantum processes. In contrast to thermodynamic proce…
