Quantum State Tomography for Matrix Product Density Operators

2023 · arXiv (Cornell University)

The reconstruction of quantum states from experimental measurements, often achieved using quantum state tomography (QST), is crucial for the verification and benchmarking of quantum devices. However, performing QST for a generic unstructured quantum state requires …

Speed limits of two-qutrit gates

2025 · arXiv (Cornell University)

The speed of elementary quantum gates sets a limit on the speed at which quantum circuits can be applied and, as a result, the size of the computations that can be performed on a quantum …
