Modulating magnetism in a Weyl semi-metal using current-assisted domain wall motion
Spintronic devices are emerging technologies that exploit the intrinsic spin of electrons to store and process data. These technologies have the potential to outperform conventional electronics both in terms of speed and ...
How silicides impact the performance of transmon qubits
Just as the sound of a guitar depends on its strings and the materials used for its body, the performance of a quantum computer depends on the composition of its building blocks. Arguably the most critical components are ...
