Direct Spectroscopic Observation of Berry Phase Interference in the Ni Single-Molecule Magnet
Brendan C. Sheehan, Robert Kwark, Charles A. Collett +3
Berry phase effects in spin systems lead to the suppression of tunneling effects when different tunneling paths interfere destructively. Such effects have been seen in several sing…

Constructing Clock-Transition-Based Two-Qubit Gates from Dimers of Molecular Nanomagnets
Charles A. Collett, Paolo Santini, Stefano Carretta +1
A good qubit must have a coherence time long enough for gate operations to be performed. Avoided level crossings allow for clock transitions in which coherence is enhanced by the i…

A Clock Transition in the CrMn Molecular Nanomagnet
Charles A. Collett, Kai-Isaak Ellers, Nicholas Russo +4
A viable qubit must have a long coherence time . In molecular nanomagnets is often limited at low temperatures by the presence of dipole and hyperfine interactions, whic…
