Generating maximally entangled Bell states is a long‐standing goal for practical quantum information processing. Mechanical resonators, as macroscopic bosonic modes with long coherence times and rich nonlinear resources, have recently been endowed with a powerful squeezing resource: two‐phonon drive can be leveraged...
Implementing high-fidelity multiqubit gates is critical for reducing circuit depth in near-term quantum processors and fault-tolerant architectures. However, realizing multiqubit interactions and entanglement remains a critical challenge that limits the implementation of multiqubit gates. Here we propose an all-microwa...

Altermagnets, characterized by vanishing net magnetization and momentum-dependent spin splitting, provide a promising platform for next-generation Josephson devices. Here, we exploit the Josephson effect in superconductor-altermagnet-superconductor junctions and show how to engineer prescribed current-phase relations b...
