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…
Attaining Quantum Sensing Enhancement from Monitored Dissipative Time Crystals
Eoin O'Connor, Victor Montenegro, Francesco Albarelli +3
This study investigates quantum-enhanced parameter estimation through continuous monitoring in open quantum systems that exhibit a dissipative time crystal phase. We first analytic…
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-enhanced sensing of spin-orbit coupling without fine tuning
Bin Yi, Abolfazl Bayat, Saubhik Sarkar
Spin-orbit coupling plays an important role in both fundamental physics and technological applications. Precise estimation of the spin-orbit coupling is necessary for accurate desi…
Observation of Criticality-Enhanced Quantum Sensing in Nonunitary Quantum Walks
Lei Xiao, Saubhik Sarkar, Kunkun Wang +2
Quantum physics enables parameter estimation with precisions beyond the capability of classical sensors. Quantum criticality is a key resource for this quantum-enhanced sensing, bu…
