Experimental Superposition of Time Directions: Quantum Time Flip Photonic Data

A research dataset from a photonic experiment demonstrating a quantum process probed in a coherent superposition of forwards and backwards time directions. The work introduces the 'quantum time flip' operation and applies it to a discrimination task game. The dataset was created by Teodor Strömberg at the University of Vienna and is available via paperswithcode.

Use Cases

• Benchmarking quantum advantage in discrimination tasks based on the described game formulation.
• Studying processes with indefinite time direction based on the quantum time flip operation.
• Comparing quantum strategies with fixed time direction versus indefinite causal order based on the described computational advantage.

Strengths

• Describes a first-time experimental demonstration of a new class of quantum processes.
• Includes a photonic realisation of the quantum time flip operation.
• The associated game serves as a witness for indefinite time direction and demonstrates computational advantage.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
