Abstract: (Elsevier Inc.)

The X-ray photons emitted by the accretion disks around rotating black holes are polarized and acquire orbital angular momentum, two degrees of freedom that can encode quantum information. Nevertheless, escaping the accretion disk, photons are passing throughout the extreme warped and twisted spacetime near spinning black holes suffering rotations of polarization angle and changes in the orbital angular moment. We conjecture that these changes in the angle of polarization and orbital angular momentum can implement elementary quantum gates and simple quantum circuits. Consequently, when detected by an asymptotic observer, the photons emitted near rotating black holes encode quantum information that can be measured by actual quantum information technology.
