Quantum error correction for multiparameter metrology
Mauricio Gutiérrez, Chiranjib Mukhopadhyay, Victor Montenegro +1
For single-parameter sensing, Greenberger-Horne-Zeilinger (GHZ) probes achieve optimal quantum-enhanced precision across the unknown parameter range, solely relying on parameter-in…
Near-Ultimate Quantum-Enhanced Sensitivity in Dissipative Critical Sensing with Partial Access
Dingwei Zhao, Abolfazl Bayat, Victor Montenegro
Quantum sensors are powerful devices that exploit quantum effects to detect minute quantities with extremely high precision. Two obstacles to harnessing the full capacity of quantu…
Beating joint quantum estimation limits with stepwise multiparameter metrology
Chiranjib Mukhopadhyay, Abolfazl Bayat, Victor Montenegro +1
Conventional multiparameter quantum sensing relies on joint estimation, but this approach faces two key limitations: theoretical bounds may be unattainable due to measurement incom…
Thermal avalanches in isolated many-body localized systems
Muhammad Sajid, Rozhin Yousefjani, Abolfazl Bayat
Many-body localization is a profound phase of matter affecting the entire spectrum which emerges in the presence of disorder in interacting many-body systems. Recently, the stabili…
Discrete time crystal for periodic-field sensing with quantum-enhanced precision
Rozhin Yousefjani, Saif Al-Kuwari, Abolfazl Bayat
Sensing periodic-fields using quantum sensors has been an active field of research. In many of these scenarios, the quantum state of the probe is flipped regularly by the applicati…
Metrological symmetries in singular quantum multi-parameter estimation
George Mihailescu, Saubhik Sarkar, Abolfazl Bayat +2
The theoretical foundation of quantum sensing is rooted in the Cramér-Rao formalism, which establishes quantitative precision bounds for a given quantum probe. In many practical sc…
