| description | Quantum computing engineering integrates quantum electronic engineering and computer science required to develop quantum computer hardware and software. In this study, we used four experiments (a single spin experiment, a giant spin experiment, a nanomagnet experiment, and the Stern–Gerlach experiment) to demonstrate that a single spin was much more energy efficient due to its small size and weak coupling with the surroundings. We conclude that quantum spintronics, with a single spin as a qubit, is a near-Landauer-bound computing engineering. This means that it is approaching the theoretical limit on the minimum amount of energy required to perform a computation, as defined by Landauer's principle. Our study is also the first experimental verification of Landauer's bound on a single spin, which is the smallest information carrier in size. |
