A Self-Assembled Metallo-Macrocycle Two-Qubit Spin System A self-assembled, charge-neutral dicopper(II) metallo-macrocycle with near degenerate singlet-triplet ground state is a prototype molecular two-qubit system. The weakly-coupled spin centres delivered a long phase memory time of 5.4 μs, and each spin can be selectively switched using an applied potential providing a convenient means to modulate the quantum levels.

1. IntroductionClick to copy section linkSection link copied!A biphenyl motif is a core component in applications as diverse as atropisomeric ligands, switches, sensors, light-emitting diodes, and liquid crystals. Homocoupling of aryl halides provides a simple route to symmetrical biphenyls, (1) and in 1971, Semmelhack reported the first nickel-based methodology to achieve this.
