Advances in Quantum Precision Measurement

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.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Quantum Reports is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
