I am a physicist, currently a research fellow at ICFO in the group of Maciej Lewenstein. My interest in disordered systems led me to two topics I have been working on recently:
Distribution of quantum entanglement on networks
This work is part of the larger problem of preparing, between distant parties, entangled states
that are consumed when performing quantum computational tasks. One begins with quantum
systems occupying vertices of a graph which can be, for instance, a regular lattice, or a complex
network. The entanglement is encoded in the edges of the graph. Various studies
have considered initial states and subsystems that are bipartite, multipartite, pure, or mixed; but the
entanglement is always local. The questions then concern manipulating the initial
system (using a restricted class of operations) to entangle widely separated nodes.
For instance: What is the most efficient protocol
for achieving long-range entanglement ? Given a class of networks, is
there a minimum entanglement below which long-range entanglement is impossible?
Anomalous transport on cell membranes
I am working in a collaboration between the groups of
Maciej Lewenstein
and María García-Parajo
at ICFO. We study anomalous transport of transmembrane receptors in eukaryotic cells.
This is part of the larger question of the origin and functional significance
of subdiffusive motion of subcellular structures, which has become a major focus of
research. We look for answers to questions such as: Is the subdiffusive motion due
to energetic traps, or geometric traps, or both ? What are the scales of inhomogeneity
in the effective matrix that the receptors see, or are there scale-free regimes ?
