Concerted efforts are underway to establish an infrastructure for a global quantum Internet to
realise a spectrum of quantum technologies. This will enable more precise sensors, secure …

Advances in quantum technologies are giving rise to a revolution in the way fundamental
physics questions are explored at the empirical level. At the same time, they are the seeds …

The establishment of quantum communication links over a global scale is enabled by
satellite nodes. We examine the influence of the Earth's atmosphere on the performance of …

In this study, we investigate the quasinormal modes (QNMs) of a Lorentz-violating
spacetime, factoring in a cosmological constant, within the framework of Einstein-bumblebee …

High-precision time transfer is of fundamental interest in physics and metrology. Quantum
time transfer technologies that use frequency-entangled pulses and their coincidence …

Although quantum synchronization phenomena and corresponding measures have been
widely discussed recently, it is still an open question how to characterize directly the …

We study Gaussian quantum steering and its asymmetry in the background of a
Schwarzschild black hole. We present a Gaussian channel description of quantum state …

At the beginning of the previous century, Newtonian mechanics was advanced by two new
revolutionary theories, Quantum Mechanics (QM) and General Relativity (GR). Both theories …

We propose the protocol for noise-resilient frequency synchronization (syntonization) of
distant clocks' local oscillators through a distributed quantum network. The syntonization is …

High-precision nonlocal temporal correlation identification in entangled photon pairs is
critical to measure the time offset between remote independent time scales for many …
