We revisit fundamental properties of quantum information in light of
a notion in one-shot information theory, namely smooth max-relative
entropy. We show how these properties, in particular Strong Subadditivity
of von Neumann entropy, follow from intuitive and easy to establish
properties of the new notion.

Invited Speaker / Conférencier invité
Quantum information theory can be viewed as a theory of inter-conversions among different resources. These resources can be classical or quantum, static (like entanglement) or dynamic (like a quantum channel), noisy or noiseless, and therefore give rise to a plethora of quantum information processing tasks. In this talk, I will give an overview on the structure of quantum resource theories and...

Communication of quantum information, like its classical counterpart, requires data synchronization. In other words, one must be able to store the information and retrieve it when needed. An optical quantum memory is an interface that stores the information encoded in a photon and recalls it on demand. A promising protocol to implement a practical optical quantum memory is the Atomic Frequency...

NMR ensemble quantum processors can be used for implementing a universal quantum circuit with a limited number of qubits using current technologies. The computation is carried out with high fidelity over a large number of processors (individual molecules) in parallel and the readout corresponds to ensemble averages of single-qubit observables. This type of readout poses a obstacle when the...

In this talk, I will explore the applications of relativistic quantum information theory to metrology. By considering the relativistic effects on the transition probability of atoms moving through the optical cavities, we will characterize the perturbations of the general trajectories of an atom. Moreover, since the atom’s transition rate depends on how the detector enters the cavity, we will...
