    The capacity of black holes to transmit quantum information 
    Bradler, Kamil; Adami, Christoph (Springer, 2014-05-21)
    We study the properties of the quantum information transmission channel that emerges from the quantum dynamics of particles interacting with a black hole horizon. We calculate the quantum channel capacity in two limiting ...

    Hiking a generalized Dyck path: a tractable way of calculating multimode boson evolution operators 
    Bradler, Kamil (Elsevier, 2015-11)
    A time evolution operator in the interaction picture is given by exponentiating an interaction Hamiltonian H. Important examples of Hamiltonians, often encountered in quantum optics, condensed matter and high energy physics, ...

    The structure of superqubit states 
    Borsten, L.; Bradler, Kamil; Duff, M. J. (Societa Italiana di Fisica, 2015-08)
    Superqubits provide a supersymmetric generalisation of the conventional qubit in quantum information theory. After a review of their current status, we address the problem of generating entangled states. We introduce the ...
