Weighted graph states as a resource for quantum metrology
B. J. Alexander, Ş. K. Özdemir, M. S. Tame
Quantum metrology exploits quantum mechanical effects to increase the precision of measurements of physical quantities. A wide variety of applications are currently being developed…
Resolving the topology of encircling multiple exceptional points
Chitres Guria, Qi Zhong, Sahin K. Ozdemir +3
Non-Hermiticity has emerged as a new paradigm for controlling coupled-mode systems in ways that cannot be achieved with conventional techniques. One aspect of this control that has…
Non-universality of quantum noise in optical amplifiers operating at exceptional points
L. Simonson, S. K. Ozdemir, A. Eisfeld +2
The concept of exceptional points-based optical amplifiers (EPOAs) has been recently proposed as a new paradigm for miniaturizing optical amplifiers while simultaneously enhancing…
Linear response theory of open systems with exceptional points
A. Hashemi, K. Busch, D. N. Christodoulides +2
Understanding the linear response of any system is the first step towards analyzing its linear and nonlinear dynamics, stability properties, as well as its behavior in the presence…
Squeezing-enhanced quantum sensing with quadratic optomechanics
Sheng-Dian Zhang, Jie Wang, Qian Zhang +6
Cavity optomechanical (COM) sensors, enhanced by quantum squeezing or entanglement, have become powerful tools for measuring ultra-weak forces with high precision and sensitivity.…
Non-Hermitian engineering of terahertz light using exceptional points in electrically tuneable collective light-matter interactions
M. Said Ergoktas, Sina Soleymani, Nurbek Kakenov +8
The topological structure associated with the branchpoint singularity around an exceptional point (EP) provides new tools for controlling the propagation of electromagnetic waves a…
