Entanglement is the most basic resource and also the most intrinsic property of quantum mechanical systems. We are studying the dynamics of the creation and destruction of entanglement in various physical systems, and in different regimes, from conservative to dissipative, from weak to ultrastrong interactions, and also in relativistic settings.
Quantum Cryptography is the first and most successful applications in QIPC. We are strongly focused on technological applications, aiming at the deployment of a cryptographic system that integrates with existing telecom networks, and the development of new key distillation schemes and routing algorithms.
For QIPC applications, that is for Quantum Information Processing and Communication, it is crucial first to know the quantum states we are creating and second to be able to do it. These ingredients are know as quantum tomography and quantum control, and both are fields of active research with many experimental and technological applications
There are many different physical systems, such as trapped ions, ultracold atoms and molecules, or superconducting circuits, which are suitable candidates for building quantum computers. Our work focuses on precise proposals that can be experimentally implemented, while studying theoretically models of its performance.
Quantum Information provides us two means for understanding quantum many-body systems. One toolbox is theoretical and makes use of numerical simulations, the other toolbox is experimental and uses a simplified version of the methods needed to build quantum computers. The combination of both sets is a formidable axe to simulate the laws of Nature or design new materials.
