Another important step towards quantum technologies based on atomic spins on surfaces from colleagues @QNSscience: 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.

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
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...

Just imagine if you could build quantum technologies by assembling qubits using atom manipulation in the STM. In a major step towards this, experiments @QNSscience have demonstrated universal quantum control on TiH qubits on MgO using ESR-STM:

With colleagues @MPSDHamburg and @unipr we have used the Nernst effect to explore fluctuations in the exotic superconductor K3C60. Surprisingly for an isotropic system, we detect fluctuations at temperatures up to four times Tc! Read all about it in PRX:
journals.aps.org
Precursors of superconductivity well above the critical temperature in K${}_{3}$C${}_{60}$ imply the presence of Cooper pairs at high temperature, which may help explain why light can raise the...

Epitaxial strain in ferroelectric multilayers gives rise to rich textures in the order parameter, witnessed, via spin-electric couplings, by embedded magnetic ions. Here, we explore ferroelectric vortices in PTO/STO superlattices using ESR on Fe dopants:
pubs.acs.org
Solid-state materials are currently being explored as a platform for the manipulation of spins for spintronics and quantum information science. More broadly, a wide spectrum of ferroelectric materi...

Various unusual features emerge in superconductors close to a Mott transition. Work led by colleagues @MPSDHamburg indicates that a light-induced superconducting state might be among them:
