Robust Tripartite Entanglement Generation via Correlated Noise in Spin Qubits
Sander Driessen, Ji Zou, Even Thingstad +2
We investigate the generation of genuine tripartite entanglement in a triangular spin-qubit system due to spatially correlated noise. In particular, we demonstrate how the formatio…
Emergent ac Effect in Nonreciprocal Coupled Condensates
Ji Zou, Valerii K. Kozin, Daniel Loss +1
We report an emergent ac Josephson-like effect arising without external bias, driven by the interplay between nonreciprocity and nonlinearity in coupled condensates. Using a minima…
Heisenberg-limited metrology from the quantum-quench dynamics of an anisotropic ferromagnet
Z. M. McIntyre, Ji Zou, Jelena Klinovaja +1
The emerging field of quantum magnonics seeks to understand and harness the quantum properties of magnons -- quantized collective spin excitations in magnets. Squeezed magnon state…
Topological Spin Textures Enabling Quantum Transmission
Ji Zou, Stefano Bosco, Jelena Klinovaja +1
Quantum spintronics is an emerging field focused on developing novel applications by utilizing the quantum coherence of magnetic systems. A key challenge in this context is achievi…
Density Matrix Renormalization Group Study of Domain Wall Qubits
Guanxiong Qu, Ji Zou, Daniel Loss +1
Nanoscale topological spin textures in magnetic systems are emerging as promising candidates for scalable quantum architectures. Despite their potential as qubits, previous studies…
Magnonic Josephson junctions and synchronized precession
Kouki Nakata, Ji Zou, Jelena Klinovaja +1
There has been a growing interest in non-Hermitian physics. One of its main goals is to engineer dissipation and to explore ensuing functionality. In magnonics, the effect of dissi…
