El IFF-CSIC inicia se ciclo de seminarios con la charla de Alejandro González Tudela que se celebrará el próximo miércoles 29 de enero en la Sala de Conferencias de Serrano 121 a las 12.00 h sobre aplicaciones de computación cuántica en física molecular y química cuántica.
Current efforts have focused on mapping the electronic problem into qubits in order to solve it with a quantum computer . However, these methods will be limited by noise until fault-tolerant devices are built. In this talk, I will present a complementary approach to quantum computers that consists in simulating quantum chemistry problems in an analogue way using ultra-cold fermionic atoms .
The talk will be divided in two parts. First, I will provide a pedagogical introduction to the field of quantum simulation, with special emphasis of the motivation and challenges of analog quantum simulation. In the second part, I will explain how to build an analog quantum simulator of chemistry using ultra-cold fermionic atoms in optical lattices. Here we will explain both how to obtain the different parts of the electronic Hamiltonian with cold atoms, and then show how the first experiments will look like.
