Magnetic-field cycling triplet-DNP/NMR system for true quantum computation with hyperpolarized nuclear spins

摘要

Toward NMR quantum computing with hyperpolarization beyond the entanglement threshold, a system has been developed enabling dynamic nuclear polarization (DNP) using photo-excited triplet electron spins with X-band microwave apparatus, followed by solid-state NMR experiments using the polarized nuclear spin system. In order to perform the triplet-DNP and NMR experiments in different magnetic fields, the triplet-DNP system and the NMR system are made to be spatially separated, between which the sample can be shuttled. It is shown that the system developed in this work fulfils the requirements for solid-state NMR quantum computing with hyperpolarized nuclear spin systems.
