Electrically tunable spin qubits in strain-engineered graphene p-n junctions

arXiv:2512.14508v2 Announce Type: replace-cross Abstract: Strain engineering enables quantum confinement in pristine graphene without degrading its intrinsic mobility and spin coherence. Here, we extend previously proposed strain-induced charge-qubit architectures by incorporating spin degrees of freedom through Rashba spin-orbit coupling (RSOC) and Zeeman fields, enabling spin-qubit operation in single-layer graphene (SLG). In a graphene p-n junction, a strain-induced nanobubble generates a...

What's gonna happen to software engineers?

In the back of my mind, I've been thinking a lot about what's going to happen to software developers. In a metaphoric way it feels like an existential question, given that, well, I'm a software developer. The real answer is that nobody really knows.
