Clock Transitions Generated by Defects in Silica Glass
Brendan C. Sheehan, Guanchu Chen, Jonathan R. Friedman
Clock transitions (CTs) in spin systems, which occur at avoided level crossings, enhance quantum coherence lifetimes T because the transition becomes immune to the decohering e…
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…
Adjustable coupling and in-situ variable frequency EPR probe with loop-gap resonators for spectroscopy up to X-band
G. Joshi, J. Kubasek, I. Nikolov +4
In standard electron paramagnetic resonance (EPR) spectroscopy, the frequency of an experiment is set and the spectrum is acquired using magnetic field as the independent variable.…
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…
Effects of uniaxial pressure on the quantum tunneling of magnetization in a high-symmetry Mn12 single-molecule magnet
James H. Atkinson, Adeline D. Fournet, Lakshmi Bhaskaran +6
The symmetry of single-molecule magnets dictates their spin quantum dynamics, influencing how such systems relax via quantum tunneling of magnetization (QTM). By reducing a system'…
