Data for Demonstration of a Quantum Switch in a Sagnac Configuration

Experimental data accompanies the paper 'Demonstration of a Quantum Switch in a Sagnac Configuration' (arXiv:2211.12540v1). The dataset contains integrated coincidence counts and polarization tomography measurements from a quantum optics experiment. It was authored by Teodor Strömberg from the University of Vienna.

Use Cases

• Analyzing the performance of a quantum switch based on coincidence counts from commutator and anti-commutator ports.
• Reconstructing implemented unitaries based on polarization tomography measurements on individual gadgets.
• Validating theoretical models of indefinite causal order using experimental data from a Sagnac interferometer configuration.
• Comparing quantum process outcomes for horizontally versus diagonally polarized input light.

Strengths

• Data is directly linked to a specific, peer-reviewed preprint (arXiv:2211.12540v1).
• Includes example code ('read.py') for accessing the data files.
• Description provides detailed column definitions for coincidence counts and tomography measurements.

Limitations

• Row count, file size, and last update date are unknown, limiting suitability assessment.
• Column-level documentation is present but the total number of rows and data volume are unspecified.
