Extreme Violations of Leggett-Garg Inequalities for a System Evolving under Superposition of Unitaries

2025 · Physical Review Letters

The violation of Leggett-Garg inequality (LGI) indicates general temporal correlations in quantum systems that cannot be explained classically. Under unitary dynamics and projective measurements, the violation of LGI is restricted up to the temporal Tsirelson's …
