Deterministic generation of entangled photonic cluster state from interacting solid state emitters (Conference Presentation)
2017
Photons are excellent carriers of quantum information; their polarization remains coherent for long times and it is easy to measure and precisely rotate. The fundamental hurdle with photon-based quantum information processing is the lack of …

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 …

Evaluating Robust Entanglement on a Trapped Ion Platform
2023
We present proof of principle results for evaluating an entanglement volumetric benchmark [1] on trapped ion platforms. The benchmark quantifies the robustness of multipartite and bipartite entanglement using stabilizer measurements and witness functions. Each n-qubit …
