Quantum Information and Sensing Technologies

Dear Colleagues,

Quantum sensors can measure not only quantum fields in particle physics, dark matter, etc., but also classical fields such as magnetic fields, electric fields, and temperature, making them applicable to a variety of fields including fundamental physics, condensed matter physics, chemistry, and biology. Quantum measurement and sensing has the potential to overcome the limitations of conventional classical sensors in terms of sensitivity, accuracy, resolution, etc. On the other hand, quantum information processing technologies that have been cultivated are useful for solving problems that have been a challenge for classical sensors, such as the effects of blackbody radiation. Important technological developments are required to overcome the limitations and challenges of classical sensors. Thus, this Special Issue is focused on quantum information and sensing technologies, e.g., proposal or experimental demonstration of not only new quantum-inspired sensing but also new technologies for the manipulation or measurement of the quantum state, such as solid-state spin, atom, photons, etc. The topics of this Special Issue include (but are not limited to) the following:

• Quantum Sensor;
• Quantum-inspired sensor;
• Quantum technology for sensing applications;
• Quantum states for quantum measurement and sensing;
• Solid-state spin-based quantum sensor, e.g., diamond, SiC, hBN;
• Atomic quantum sensor;
• Superconductivity-based quantum sensors, e.g., SQUID;
• Photonics quantum sensors, e.g., ghost measurements, undetected quantum spectroscopy, quantum imaging, quantum optical coherence tomography;
• Quantum theory and algorithm for quantum measurements, such as entanglement-based measurements;
• Practical implementations.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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. Sensors is an international peer-reviewed open access semimonthly 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 2600 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.
