Single-shot readout

We investigate individual Ti atoms on the oxygen binding site of an MgO/Ag(100) substrate (see “Methods”), which have been shown to carry an electron spin S = 1/2 that can be ESR driven by an RF voltage at the STM…

GKP code

Here we give some background on GKP codes, highlighting some of the more salient features in our experiment and simulations. For a more comprehensive summary, see the original proposal⁶ and more recent reviews^48,49. The GKP code is a…

Figure 1 displays the spectra of ²³Na MAS NMR for (a) the LNNx system with 0.12 < x < 0.18, (b) the LNN18 aged for 8 h at a temperature T ϵ [500,800] °C and (c) the LNN18 aged for 24 h at 500 °C and at 600 °C for a time t ϵ…

Formalism

We extend the Kane-Mele model by including a collinear AFM order which is exchange coupled to the electrons on a 2D honeycomb lattice. As illustrated in Fig. 1, the magnetic moments on the A and B sublattices are oppositely aligned and…

One of the most powerful optimization methods we utilize is control reduction. The number of CX gates necessary to implement the multi-controlled Rz and Rx gates is proportional to the number of controls on those gates. As mentioned earlier, we…

Implementation of a nonlinear trimer EC lattice and the realization of quench dynamics

Although the Su-Schrieffer-Heeger lattice is the prototypical model of a topological lattice, we here investigate a one-dimensional trimer lattice with onsite…

Automatic self-consistent training of MLIPs

In order to train the interatomic potential used in our work, we developed the automatic self-consistent training (ASCT) algorithm based on iterative sampling of the new structures from the molecular…
