Coherent Rydberg excitation of single atoms using a pulsed fiber amplifier
Ying-Wen Zhang, Yang Wang, Chen-Long Xu +2
In recent years, the growing scale of programmable neutral-atom arrays has led to an increasing demand for higher-power Rydberg excitation light. Although pulsed amplifiers deliver…
Enhanced security in Quantum Token protocols using Hybrid Spin-Photon Interfaces
Durga Bhaktavatsala Rao Dasari, Yang Wang, Jörg Wrachtrup
Quantum token protocols enable unforgeable quantum tokens promising unconditional security beyond classical cryptographic assumptions. We show here that the three stages of the Qua…
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…
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…
