Post-processing of quantum instruments
Leevi Leppäjärvi, Michal Sedlák
Studying sequential measurements is of the utmost importance to both the foundational aspects of quantum theory and the practical implementations of quantum technologies, with both…
Private quantum channels for multi-photon pulses and unitary k-designs
Jan Bouda, Michal Sedlák, Mario Ziman
We address the question of existence of private quantum channel for qubits encoded in polarization degrees of freedom of a photon, that remains secure even if multi-photon (instead…
Probabilistic storage and retrieval of qubit phase gates
Michal Sedlák, Mário Ziman
Probabilistic storage and retrieval (PSR) of unitary quantum dynamics is possible with exponentially small failure probability with respect to the number of systems used as a quant…
On some new hook-content identities
Michal Sedlák, Alessandro Bisio
Based on the work of A. Vershik, we introduce two new combinatorial identities. We show how these identities can be used to prove a new hook-content identity. The main motivation f…
Quantum theory of unambiguous measurements
Michal Sedlák
In the present paper I formulate a framework that accommodates many unambiguous discrimination problems. I show that the prior information about any type of constituent (state, cha…
Single-shot discrimination of quantum unitary processes
Mario Ziman, Michal Sedlák
We formulate minimum-error and unambiguous discrimination problems for quantum processes in the language of process positive operator valued measures (PPOVM). In this framework we…
