Error-correcting entanglement swapping using a practical logical photon encoding

2021 · arXiv (Cornell University)

Several emerging quantum technologies, including quantum networks, modular and fusion-based quantum computing, rely crucially on the ability to perform photonic Bell state measurements. Therefore, photon losses and the 50\% success probablity upper bound of Bell …

Qudit Clauser-Horne-Shimony-Holt Inequality and Nonlocality from Wigner Negativity

2026 · Quantum

Nonlocality is an essential concept that distinguishes quantum from classical models and has been extensively studied in systems of qubits. For higher-dimensional systems, certain results for their two-level counterpart, like Bell violations with stabilizer states …
