Chemical tuning of quantum spin–electric coupling in molecular magnets - Nature Chemistry
Molecular magnets may serve as engineerable spin qubit candidates for quantum information science; however, the magnetic fields often used for control can be challenging to confine. Now, it has been s...

🧪 Theory is one thing, experiment is quite another! We have taken the first steps in implementing an error-correctable quantum memory on a hyperfine-coupled qudit. Read about our experiment demonstrating the encoding and exploring its dynamics: journals.aps.org/prl/abstract...

Another important step towards quantum technologies based on atomic spins on surfaces from colleagues at IBS QNS: the very high electric fields available in the STM allow for strong driving of ESR transitions, giving rise to the creation and control of dressed states. pubs.acs.org/doi/full/10....
All-Electrical Driving and Probing of Dressed States in a Single Spin
The subnanometer distance between tip and sample in a scanning tunneling microscope (STM) enables the application of very large electric fields with a strength as high as ∼1 GV/m. This has allowed for...

High spin nuclei hyperfine coupled to electron spin qubits offer a valuable quantum resource. For example, we can use them to implement quantum error correction algorithms more efficiently than qubit-based codes of equivalent effectiveness: journals.aps.org/pra/abstract...
Fault-tolerant qubit encoding using a spin-7/2 qudit
The authors propose a quantum memory, implemented on a spin-7/2 nucleus coupled to an electron spin-1/2 qubit, which provides $X$, $Y$, and $Z$ error correction using fewer quantum resources than the ...
