Singlet-only Always-on Gapless Exchange Qubits with Baseband Control
Nathan L. Foulk, Silas Hoffman, Katharina Laubscher +1
We propose a singlet-only always-on gapless exchange (SAGE) spin qubit that encodes a single qubit in the spins of four electrons while allowing universal baseband control. While c…
Scattering solution of interacting Hamiltonian for electronic control of molecular spin qubits
Christian Bunker, Silas Hoffman, Jie-Xiang Yu +2
We theoretically study how a scattered electron can entangle molecular spin qubits (MSQs). This requires solving the inelastic transport of a single electron through a scattering r…
Majorana Zero Modes Emulated in a Magnetic Molecule Chain
Silas Hoffman, Jie-Xiang Yu, Shuang-Long Liu +6
We propose molecular magnets as a platform to emulate Majorana zero modes (MZMs). Using a quantum chemistry approach, we identify several candidates and predict a Co trimer to have…
Demonstration of electron-nuclear decoupling at a spin clock transition
Krishnendu Kundu, Jia Chen, Silas Hoffman +7
The ability to design quantum systems that decouple from environmental noise sources is highly desirable for development of quantum technologies with optimal coherence. The chemica…
Universal quantum operation of spin-3/2 Blume-Capel chains
Silas Hoffman, Yiyuan Chen, Hai-Ping Cheng +1
We propose a logical qubit based on the Blume-Capel model: a higher spin generalization of the Ising chain and which allows for an on-site anisotropy preserving rotational invarian…
Tuning interactions between spins in a superconductor
Hao Ding, Yuwen Hu, Mallika T. Randeria +5
Novel many-body and topological electronic phases can be created in assemblies of interacting spins coupled to a superconductor, such as one-dimensional topological superconductors…
