Exact identification of unknown unitary processes
Santiago Llorens, Arnau Diebra, Michal Sedlák +1
The accurate identification of faulty hardware is a fundamental requirement for reliable quantum information processing. We address this problem in a quantum setting, where a serie…

Sequential realization of Quantum Instruments
Soham Sau, Michal Sedlák
In adaptive quantum circuits classical results of mid-circuit measurements determine the upcoming gates. This allows POVMs, quantum channels or more generally quantum instruments t…

Storage and retrieval of two unknown unitary channels
Michal Sedlák, Robert Stárek, Nikola Horová +3
We address the fundamental task of converting uses of an unknown unitary transformation into a quantum state (i.e., storage) and later retrieval of the transformation. Specific…
