Multicopy quantum state teleportation with application to storage and retrieval of quantum programs
Frédéric Grosshans, MichaŠHorodecki, Mio Murao +4
This work considers a teleportation task for Alice and Bob in a scenario where Bob cannot perform corrections. In particular, we analyse the task of \textit{multicopy state telepor…
Group-Adapted Irreducible Matrix Units for the Walled Brauer Algebra
MichaÅ StudziÅski, Tomasz MÅynik, Marek Mozrzymas +2
This paper investigates the representation theory of the algebra of partially transposed permutation operators, , which provides a matrix representation for th…
Optimal universal quantum circuits for unitary complex conjugation
Daniel Ebler, MichaÅ Horodecki, Marcin Marciniak +3
Let be a unitary operator representing an arbitrary -dimensional unitary quantum operation. This work presents optimal quantum circuits for transforming a number of ca…
Characterization of -positive maps
Marcin Marciniak, Tomasz MÅynik, Hiroyuki Osaka
We present a general characterization of k-positivity for a positive map in terms of the estimation of the Ky Fan norm of the matrix constructed from the Kraus operators of the ass…
