We study the computational complexity of $c$-Colored $P_\ell$ Deletion and $C_\ell$ Deletion. In these problems, one is given a $c$-edge-colored graph wants to destroy all induced $c$-colored paths or cycles, respectively, on $\ell$ vertices by deleting at most $k$ edges. Herein, path cycle if it contains edges $c$ distinct colors. show that are NP-hard for each non-trivial combination $\ell$. ...

Nondestructive quantum measurements are central for physics applications ranging from sensing to computing and communication. Employing the toolbox of cavity electrodynamics, we here concatenate two identical nondestructive photon detectors repeatedly detect track a single propagating through $60\,\mathrm{m}$ long optical fiber. By demonstrating that combined signal-to-noise ratio surpasses eac...

A bstract The destruction of the event horizon a nonsingular black hole, which is not prevented by weak cosmic censorship conjecture, might provide us possibility to access quantum regime gravity inside hole. We investigate overspinning rotating quantum-corrected hole test particle and scalar field in this paper, analyse effect parameter on horizon. For injection, both extremal near-extremal ho...
