Quantum-enhanced sensing in a driven-dissipative system via chiral waveguide
Yan Xi Foo, Saubhik Sarkar, Leong Chuan Kwek +2
Quantum sensors can achieve precision unattainable by classical sensors. However, dissipation coming from interaction with the environment can greatly degrade the performance of qu…
Modular non-Hermitian topology and its application to critical sensing
Saubhik Sarkar, Chiranjib Mukhopadhyay, Abolfazl Bayat
Non-Hermitian topological systems have attracted a lot of research activities in recent times, both theoretically and experimentally, due to their unique physical properties and as…
Nonlinearity-enhanced Quantum Sensing in Discrete Time Crystal Probes
Rozhin Yousefjani, Shaikha Al-Naimi, Saif Al-Kuwari +1
Discrete time crystals are non-equilibrium phases of matter in periodically driven systems, characterized by robust subharmonic oscillations and broken discrete time-translation sy…
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…
Non-Equilibrium Criticality-Enhanced Quantum Sensing with Superconducting Qubits
Hao Li, Yaoling Yang, Yun-Hao Shi +24
Exploiting quantum features allows for estimating external parameters with precisions well beyond the capacity of classical sensors, a phenomenon known as quantum-enhanced precisio…
