Singlet-only always-on gapless exchange (SAGE) spin qubits: Charge noise effects and two-qubit gates
Nathan L. Foulk, Katharina Laubscher, Silas Hoffman +1
Singlet-only always-on gapless exchange (SAGE) spin qubits are an alternative type of exchange-only (EO) qubits that encode a single qubit in the spins of four electrons located in…
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…
