Molecular Spins for Quantum Technologies
Abstract
The objective of this collaborative project involving Osaka City University (Japan), the University of Modena and Reggio Emilia (Italy), and Florida State University (USA), is to investigate the quantum behavior of spins in magnetic molecules (molecular spins) in order to determine viable systems and conditions for qubit (quantum bit) encoding and, more generally, for the realization of memory/logic devices working in the quantum regime. Specific goals include: the search for optimal conditions to manipulate molecular spins by microwave pulses; the conditioned dynamics of two or more molecular spins (i.e., quantum logic gates); and the coherent coupling of molecular spins with superconducting circuits. These challenges require a multidisciplinary effort involving teams with different skills, instrumentation, and theoretical tools. In particular, collaboration between physicists and chemists is essential in order to direct the chemical engineering and optimization of molecules with the required quantum states/properties, and also to ensure the development of appropriate (and unique) microwave resonance techniques, devices and protocols. Because the required expertise cannot be found within a single country (or even continent), international cooperation is essential. Multiple exchanges of personnel (including students) will take place between the partner institutions in order to maximize cross-fertilization of ideas and information. Recent work by this team has shown that molecular spins have performances that compare well with those of other solid-state qubits. In contrast to these other approaches, molecular spins offer significant advantages in terms of low-cost self-assembly into ordered 1D, 2D, or 3D arrays with atomic precision. As such, they show tremendous potential for scaling-up quantum computation to a point where implementation of quantum error correction may become possible.
