DOI: 10.1038/s41598-018-27605-9
Abstract: The quantum Zeno effect is deeply related to the quantum measurement process and thus studies of it may help shed light on the hitherto mysterious measurement process in quantum mechanics. Recently, the spatial quantum Zeno… read more here.

DOI: 10.1103/physreva.95.042132
Abstract: We investigate the quantum Zeno and anti-Zeno effects in quantum dissipative systems by employing a hierarchical equations of motion approach which is beyond the usual Markovian approximation, the rotating wave approximation, and the perturbative approximation.… read more here.

DOI: 10.1103/physreva.98.012135
Abstract: In this work, we study the decay behavior of a two-level system under the competing influence of a dissipative environment and repetitive measurements. The sign of the second derivative of the environmental spectral density function… read more here.

DOI: 10.1103/physrevlett.129.070502
Abstract: In open quantum systems, the precision of metrology inevitably suffers from the noise. In Markovian open quantum dynamics, the precision can not be improved by using entangled probes although the measurement time is effectively shortened.… read more here.

DOI: 10.1140/epjd/s10053-021-00168-7
Abstract: In this paper, we study the dynamics of atom–atom entanglement inside a single-mode cavity using quantum Zeno dynamics (QZD). The system under study consists of two two-level atoms with dipole–dipole and Ising interactions. By applying… read more here.

DOI: 10.1364/oe.464550
Abstract: The quantum Zeno effect reveals that continuous observation of a quantum system can significantly alter its evolution. Here, we present a method for establishing polarization entanglement between two initially unentangled photons in coupled waveguides via… read more here.
