Achieving Heisenberg limit under noisy conditions with quantum Zeno dynamics and dynamical decoupling
Ke Zeng, Bakmou Lahcen, Yu Jiang +1
Quantum Zeno dynamics (QZD) and dynamical decoupling (DD) are useful tools that enable the effective suppression of noise in quantum systems. We consider the problem of when (i) no…
Restoring Heisenberg-Limited Precision in Non-Markovian Open Quantum Systems via Dynamical Decoupling
Bakmou Lahcen, Ke Zeng, Yu Jiang +1
Non-classical resources enable measurements to achieve a precision that exceeds the limits predicted by the central limit theorem. However, environmental noise arising from system-…
Kirkwood-Dirac Type Quasiprobabilities as Universal Identifiers of Nonclassical Quantum Resources
Kok Chuan Tan, Souradeep Sasmal
We show that a Kirkwood-Dirac type quasiprobability distribution is sufficient to reveal any arbitrary quantum resource. This is achieved by demonstrating that it is always possibl…
Fisher information universally identifies quantum resources
Kok Chuan Tan, Varun Narasimhachar, Bartosz Regula
We show that both the classical as well as the quantum definitions of the Fisher information faithfully identify resourceful quantum states in general quantum resource theories, in…
Variational quantum algorithms to estimate rank, quantum entropies, fidelity and Fisher information via purity minimization
Kok Chuan Tan, Tyler Volkoff
Variational quantum algorithms (VQAs) that estimate values of widely used physical quantities such as the rank, quantum entropies, the Bures fidelity and the quantum Fisher informa…
Error mitigation in quantum metrology via zero noise extrapolation
Zhuo Zhao, Kok Chuan Tan
We consider Zero Noise Extrapolation (ZNE) as an error mitigation strategy in quantum metrology. It is shown that noise expansion can be systematically performed over sufficiently…
