Using near-flat-band electrons for read-out of molecular spin qubit entangled states
Christian Bunker, Silas Hoffman, Shuanglong Liu +2
While molecular spin qubits (MSQs) are a promising platform for quantum computing, read-out has been largely limited to electron paramagnetic resonance which is often slow and requ…
Simulating decoherence of two coupled spins using the generalized cluster correlation expansion
Xiao Chen, Silas Hoffman, James N. Fry +1
We simulate the coherence of two coupled electron spins interacting with a bath of nuclei using the generalized cluster correlation expansion (gCCE) method. An exchange interaction…
Floquet Engineering Clock Transitions in Magnetic Molecules
Andrew Cupo, Shuanglong Liu, Silas Hoffman +2
We theoretically study Floquet engineering of magnetic molecules via a time-periodic magnetic field that couples to the emergent total electronic spin of the metal center. By focus…
Dominant spin-spin relaxation mechanism at clock transition of the complex at different concentrations
Xiao Chen, Haechan Park, Silas Hoffman +2
Spin decoherence poses a significant challenge in molecular magnets, with the nuclear spin bath serving as a prominent source. Intriguingly, spin qubits at the clock transition exh…
Accurate crystal field Hamiltonians of single-ion magnets at mean-field cost
Linqing Peng, Shuanglong Liu, Xing Zhang +4
The effective crystal field Hamiltonian provides the key description of the electronic properties of single-ion magnets, but obtaining its parameters from ab initio computation is…
Discovery of Spin-Crossover Candidates with Equivariant Graph Neural Networks and Relevance-Based Classification
Angel Albavera-Mata, Pawan Prakash, Jason B. Gibson +7
Swift discovery of spin-crossover materials for their potential application in quantum information devices requires techniques which enable efficient identification of suitably bis…
