Quantum Coding with Finite Thermodynamic Resources
Jake Xuereb, Tiago Debarba, Marcus Huber +1
Quantum direct coding or Schumacher compression generalised the ideas of Shannon theory, gave an operational meaning to the von Neumann entropy and established the term qubit. But…
Experimental high-dimensional entanglement certification and quantum steering with time-energy measurements
Kai-Chi Chang, Murat Can Sarihan, Paul Erker +8
High-dimensional entanglement provides unique ways of transcending the limitations of current approaches in quantum information processing, quantum communications based on qubits.…
Key Issues Review: Useful autonomous quantum machines
José Antonio Marín Guzmán, Paul Erker, Simone Gasparinetti +2
Controlled quantum machines have matured significantly. A natural next step is to increasingly grant them autonomy, freeing them from time-dependent external control. For example,…
The Impact of Imperfect Timekeeping on Quantum Control
Jake Xuereb, Florian Meier, Paul Erker +2
In order to unitarily evolve a quantum system, an agent requires knowledge of time, a parameter which no physical clock can ever perfectly characterise. In this letter, we study ho…
Fundamental accuracy-resolution trade-off for timekeeping devices
Florian Meier, Emanuel Schwarzhans, Paul Erker +1
From a thermodynamic point of view, all clocks are driven by irreversible processes. Additionally, one can use oscillatory systems to temporally modulate the thermodynamic flux tow…
