Quantum switch for itinerant microwave single photons with superconducting quantum circuits

2024 · Physical Review Applied

A classical switch or router determines which of several inputs to the device passes through the output. In analogy, a quantum switch that coherently links the input to a superposition of several outputs plays an …

Robust Mølmer-Sørensen Gate Against Symmetric and Asymmetric Errors

2025 · arXiv (Cornell University)

To achieve the entangling gate fidelity above the quantum error correction threshold, it is critical to suppress errors due to experimental imperfection. We consider the Mølmer-Sørensen gates in trapped-ion systems, and develop a general approach …

Realization of a functioning dual-type trapped-ion quantum network node

2025 · Science Advances

Trapped ions constitute a promising platform for implementation of a quantum network. Recently, a dual-type qubit scheme has been realized in a quantum network node where communication qubits and memory qubits are encoded in different …
