Ultrafast entangling gates between nuclear spins using photoexcited triplet states

Abstract:

The representation of information within the spins of electrons and nuclei has been a powerful method in the ongoing development of quantum computers 1,2. Although nuclear spins are advantageous as quantum bits (qubits) because of their long coherence lifetimes (exceeding seconds 3), they exhibit very slow spin interactions and have weak thermal polarization. A coupled electron spin can be used to polarize the nuclear spin 4-6 and create fast single-qubit gates 7,8, however, the permanent pre...
