Descripción del proyecto
Los cúdits de espines moleculares: una nueva esperanza para la computación cuántica
La espintrónica molecular está siendo un soplo de aire fresco para las tecnologías cuánticas. La computación cuántica es posible gracias a un control y una manipulación cuidadosos del espín de los electrones en una molécula. El proyecto FATMOLS, financiado con fondos europeos, tiene la finalidad de construir una prueba de concepto para un procesador cuántico de espines moleculares. Las moléculas magnéticas artificiales que funcionan como cúdits, con muchos estados cuánticos simultáneos, se controlarán, leerán y vincularán a través de un acoplamiento uniforme en circuitos superconductores en chip. Este nuevo planteamiento integrará funciones cuánticas en tres escalas diferentes (espines nucleares, espines electrónicos y circuitos), será flexible e intrínsecamente modular y, por tanto, modulable. Se espera que los resultados del proyecto tengan grandes repercusiones en la instrumentación de resonancia magnética.
Objetivo
FATMOLS introduces a new paradigm in the world of quantum technologies: the molecular spin quantum processor. Artificial magnetic molecules that realize spin qudits, with multiple addressable quantum spin states, are controlled, read-out and linked via their coherent coupling to on-chip superconducting circuits. This novel scheme integrates quantum functionalities at three different scales (nuclear spins, electronic spins and circuits), is inherently modular and therefore scalable, and is also very flexible. It admits different qudit realizations, can create diverse qubit arrays and topologies and perform quantum simulations and fault-tolerant quantum computing, with quantum error correction either embedded in each molecule or distributed among different nodes in a topological lattice. FATMOLS objective is to provide a proof-of-concept of one of the repetition unit cells of this platform, involving at least two molecules with multiple and fully addressable levels, from which more complex architectures can be created. To achieve this goal, FATMOLS will design suitable algorithms and architectures for specific applications (quantum chemistry simulations, quantum error correction) and create, test and interconnect the different components of this technology (molecules, superconducting nano-resonators and control electronics), through a creative collaboration between disciplines and between top-level academic and industrial partners. In the short term, the project will reshape multi-frequency magnetic resonance instrumentation, a key enabling technology of widespread use. In the medium to long term, it will define an alternative roadmap to reach the next level of computational power (100-1000 qubits) and, therefore, address quantum optimization and quantum simulation problems with direct impact on diverse economic sectors, including agriculture, health-care, energy and artificial intelligence.
