Near-limit quantum control beyond analytic tractability in many-body spin systems
Jixing Zhang, Bo Peng, Yang Wang +11
As quantum control approaches hardware-imposed performance limits, weak effects omitted by reduced models become consequential. Assumptions required for analytic tractability then…
Super-Moiré Spin Textures in Twisted Antiferromagnets
King Cho Wong, Ruoming Peng, Eric Anderson +15
Stacking two-dimensional (2D) layered materials offers a powerful platform to engineer electronic and magnetic states. In general, the resulting states, such as Moiré magnetism, h…
Hybrid spin-phonon architecture for scalable solid-state quantum nodes
Ruoming Peng, Xuntao Wu, Yang Wang +5
Solid-state spin systems hold great promise for quantum information processing and the construction of quantum networks. However, the considerable inhomogeneity of spins in solids…
Remote Cooling of Spin-ensembles through a Spin-mechanical Hybrid Interface
Yang Wang, Durga Bhaktavatsala Rao Dasari, Jörg Wrachtrup
We present a protocol for the ground-state cooling of a tripartite hybrid quantum system, in which a macroscopic oscillator acts as a mediator between a single probe spin and a rem…
Cooling limits of coherent refrigerators
Rodolfo R. Soldati, Durga B. R. Dasari, Jörg Wrachtrup +1
Refrigeration limits are of fundamental and practical importance. We here show that quantum systems can be cooled below existing incoherent cooling bounds by employing coherent vir…
