Abstract

Quantum information science (QIS), initially an application of quantum physics, is now a research field in and of itself. A principal component of QIS is quantum computing (QC), which offers exponential speedup of certain computations, with applications ranging from cryptography to modeling of new molecules or materials with perspectives of tremendous impact to the society. Under this scenario, the group of Quantum Field and Quantum Information at UVA leads the generation of multimode entanglement in light fields produced by optical parametric oscillators, a strong candidate for implementations of QC, while the Laboratory of Coherent Manipulation of Light and Atoms at USP has been developing the integration of such systems using on-chip microresonators produced by lithographic techniques on CMOS compatible materials like Si and SiN Our proposal aims at marrying these two expertise for the generation of multimode entanglement states in this scalable platform, enabling the development of compact processing units for quantum information, compatible with the current technology used in semiconductor industry.
