Communication between general-relativistic observers without a shared reference frame
Agata Chȩcińska, Andrzej Dragan
We show how to reliably encode quantum information and send it between two arbitrary general-relativistic observers without a shared reference frame. Any information stored in a qu…
Dissipation enhanced vibrational sensing in an olfactory molecular switch
Agata Checinska, Felix A. Pollock, Libby Heaney +1
Motivated by a proposed olfactory mechanism based on a vibrationally-activated molecular switch, we study electron transport within a donor-acceptor pair that is coupled to a vibra…
Witnessing quantum coherence in the presence of noise
Alex Monras, Agata Chȩcińska, Artur Ekert
We address the problem of assessing the coherent character of physical evolution. We take the quantum Zeno effect (QZE) as a characteristic trait of quantum dynamics, and derive re…
Analysis of complete positivity conditions for quantum qutrit channels
A. Checinska, K. Wodkiewicz
We present an analysis of complete positivity (CP) constraints on qutrit quantum channels that have a form of affine transformations of generalized Bloch vector. For diagonal (damp…
Noisy Qutrit Channels
A. Checinska, K. Wodkiewicz
We present an analysis of spontaneous emission in a 3-level atom as an example of a qutrit state under the action of noisy quantum channels. We choose a 3-level atom with V-configu…
