Researchers have unveiled a quantum sensing scheme that achieves the pinnacle of quantum sensitivity in measuring the transverse displacement between two interfering photons.
Researchers from the University of Portsmouth have unveiled a quantum sensing scheme that achieves the pinnacle of quantum sensitivity in measuring the transverse displacement between two interfering photons.
Traditionally, achieving ultra-high precision in nanoscopic techniques has been constrained by the limitations of standard imaging methods, such as the diffraction limit of cameras and highly magnifying objectives. However, this new quantum sensing scheme circumvents these obstacles, paving the way for unprecedented levels of precision.
Study co-author Professor Vincenzo Tamma, Director of the Quantum Science and Technology Hub, said:"These results shed new light on the metrological power of two-photon spatial interference and can pave the way to new high-precision sensing techniques. Quantum states of light have enabled novel optical sensing schemes, e.g., for measuring distance or position, with precisions impossible to achieve with classical light sources such as lasers. The ...
