Special Issue Information

Dear Colleagues,

Quantum precision measurement (QPM), which harnesses fundamental quantum resources such as entanglement, squeezing, and coherence, represents a paradigm shift in our capability to probe the physical world. It moves beyond merely improving existing instruments, instead aiming to redefine the ultimate limits of the sensitivity, resolution, and accuracy of measurements set by classical physics. This field offers unprecedented opportunities to uncover faint signals, detect subtle interactions, and answer profound questions across fundamental science and technological applications.

Recent breakthroughs in the control and manipulation of quantum systems, including ultracold atoms and ions, solid-state spin defects (e.g., NV centers in diamond), photonic quantum states, and superconducting circuits, have transformed quantum sensors from laboratory curiosities into powerful burgeoning technologies. The realization of squeezed light-enhanced interferometers, entanglement-enhanced atomic clocks and interferometers, and nanoscale quantum magnetometers has demonstrated tangible paths toward surpassing the Standard Quantum Limit and approaching the Heisenberg Limit.

This Special Issue invites original research articles, comprehensive reviews, and perspectives that explore the cutting edge of QPM. We welcome contributions addressing the following topics:

  • Theoretical foundations and novel protocols for quantum-enhanced metrology, sensing, and imaging.
  • Experimental advances in key platforms: Cold-atom/ion systems, quantum optical sensors, solid-state quantum sensors (e.g., spins, superconductors), and hybrid quantum systems.
  • Enabling technologies for QPM, including quantum state preparation, control, non-destructive readout, and noise suppression techniques.
  • Forward-looking perspectives on distributed quantum sensing networks, and quantum-enhanced data processing.

This Special Issue intentionally adopts a broad scope to showcase how QPM is transcending classical boundaries. We encourage contributions that highlight the convergence of quantum information, atomic physics, photonics, and condensed matter physics. Our goal is to illuminate the field’s trajectory and accelerate its impact on scientific discovery and technological innovation.

Conventional tests of Bell’s inequality rely on entangled photon pairs. Here, we replace entangled pairs with two independent photons of orthogonal polarization and demonstrate that Bell’s inequality is still violated. Given the inherent local realism of independent photons, this experiment proves that Bell’s inequality cannot falsify the local realism of photons. We thus conjecture that the violation of Bell’s inequality by entangled photon pairs originates from their orthogonal polarizations rather than the breakdown of local realism. To interpret this unexpected violation with independent photons, we further substitute the two photons with two monochromatic light beams and calculate the transmittance correlation through polarizers via Malus’s law and Karl Pearson’s correlation formula. We show that this correlation also defies Bell’s inequality. Retracing the derivation of Bell’s inequality reveals that its validity is restricted to binary events, which accounts for the observed violation with light beams. Finally, we propose a thought experiment involving the gradual attenuation of light intensity down to the single-photon regime and hypothesize that single-photon transmission through a polarizer does not constitute a binary event. This hypothesis provides a unified interpretation for both our experimental findings and all canonical Bell inequality tests reported to date. Full article
