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…
Numerical simulations on First-order phase transition through thermal fluctuation
Ligong Bian, Yuefeng Di, Yongtao Jia +2
In this Letter, we numerically present the possibility of the first-order phase transition occurring through the thermal fluctuation in the early universe. We find that when the te…
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-…
Wide-band Unambiguous Quantum Sensing via Geodesic Evolution
Ke Zeng, Xiaohui Yu, Martin B. Plenio +1
We present a quantum sensing technique that utilizes a sequence of pulses to cyclically drive the qubit dynamics along a geodesic path of adiabatic evolution. This approach eff…
Memory effects teleportation of quantum Fisher information under decoherence
Y. N. Guo, K. zeng, P. X. Chen
We have investigated how memory effects on the teleportation of quantum Fisher information(QFI) for a single qubit system using a class of X-states as resources influenced by decoh…
Entropic uncertainty relation under quantum channels with memory
Youneng Guo, Maofa Fang, Ke Zeng
Recently, Xu et al. [Phys. Rev. A 86, 012113(2012)] explored the behavior of the entropic uncertainty relation under the influence of local unital and nonunital noisy channels for…
