Discover how quantum squeezing can revolutionize measurement accuracy across various technologies, from atomic clocks to MRI imaging.
Demystifying the quantum squeeze
Quantum squeezing, a weird thing in the world of quantum physics, is opening new frontiers in measurement precision.
Imagine a round, air-filled balloon; in its natural state it is a perfect sphere. This may flatten when you squish one side or get stretched to provide a fuller effect. If guaranteed in writing at a casino, it would be tantamount to legalized cheating on bets: a double-edged promise reducing uncertainty in one part while inflating it elsewhere — the quintessence of quantum squeezing.
It just changes the nature of the uncertainty but in such a way that allows for far nicer measurements of one these variables. The method has been used to improve atomic clocks, already the most precise timekeeping devices ever made; applying it in more complicated situations is difficult, as meaningful data must be taken on multiple variables simultaneously — a particle’s position as well as its momentum, for example.
Tapping the Many Forms of Quantum Sensing
In a new study in Physical Review Research, Dr. Le Bin Ho at Tohoku University explains the efficacy of the squeezing technique to improve measurement precision for quantum systems with two or more degrees of freedom.
Specifically, the study explores a model where an ensemble of identical two-level quantum systems are subjected to three-dimensional magnetic field. The precision of these measurements should be fundamentally limited by theory in best cases. Prior studies claimed that these could be used to generate entanglement between the respective states of two systems, but they could not elucidate how this occurs in reality, where quantum correlations are complete (i.e. maximal reinforcement) only for entanglement in a single direction.
The work of Dr. Ho gives theoretical and numerical insight that the maximum precision in these complicated measurements is achieved when we find the mechanisms responsible for the search. In doing so, they are clearing the path for more advanced quantum sensing and imaging techniques possible by applying quantum squeezing in even more challenging measurement situations.
Conclusion
The research on squeezing of quantum and multi- stage estimation is major breakthrough in the domain of quantum science. Through achieving these secrets to obtaining a higher measurement precision with this method, the investigators Have installed the inspiration for an upcoming era of quantum technology concerning in atomic clocks and Gps all the approach via means of medical imaging and bio-sensing. While the universe of quantum possibilities keeps opening up, its prospects for new realizations in theory and practice are as immense and exhilarating as ever.
