An NMR Platform for the Development of Quantum Information and Quantum Computing Protocols

Nuclear Magnetic Resonance (NMR) has been extensively employed in the fields of quantum information and quantum computing, owing to its remarkable flexibility and precise control over quantum states.

In this line of research, we are developing an NMR platform capable of generating 2- and 3-qubit computational basis states, as well as implementing a universal set of quantum logic gates. This infrastructure enables the design and execution of quantum algorithms and quantum information protocols.

To achieve this, we have developed a set of super-modulated radiofrequency pulses that enable the generation of quantum states with high fidelity. Additionally, we have implemented a quantum state tomography procedure to monitor and characterize quantum evolution throughout the proposed NMR experiments.

Furthermore, to make this quantum system accessible to users without prior NMR expertise, we are developing a computational interface capable of translating high-level quantum procedures into the specific pulse sequences required to implement them on the NMR platform.

An overview of this NMR-based quantum system will be presented during the meeting.
