Spacetime Geometry near Rotating Black Holes Acts Like Quantum Computer, Physicist Says Jan 15, 2019 by News Staff / Source Published in Computer Science Featured Physics Tagged as Accretion disk

According to a theoretical paper published in the Annals of Physics, by Dr. Ovidiu Racorean from the General Direction of Information Technology in Bucharest, Romania, the geometry of spacetime around a rapidly spinning black hole (Kerr black hole) behaves like a quantum computer, and it can encode photons with quantum messages.

This is because it is easy to use photons’ degrees of freedom to encode quantum bits (qubits) that are the standard information units in quantum computing. The term ‘degrees of freedom’ refers to those properties of the photons that take values that can be used in an equivalent manner to the ‘0’ and ‘1,’ in classical computers.

“In this research, we use polarization and orbital angular momentum (OAM) of photons as the carriers of quantum bits,” Dr. Racorean said. “The distorted geometry of spacetime near rotating black holes can create and manipulate quantum information encoded in beams of light that are emitted by, or that pass close to, these black holes.”

“This is similar to the process that happens in a theoretical quantum computer.” “A quantum computation process consists of photons traveling throughout a setup of mirrors, beam splitters, and prisms that switch the polarization and twisted phase of photons to values that can be mapped onto 0 and 1,” he added. Photons that are processed in this manner can encode quantum gates and quantum circuits that are more or less similar to those in a classical computer when they exit this setup.

“The geometry of spacetime near spinning black holes acts in an identical manner to this setup of prisms and mirrors,” Dr. Racorean said. This means that a spinning black hole writes a quantum code that we may decode in the near future when we come to create quantum computers. “We are now on the verge of a new technological era, an era that will be dominated by quantum technology,” Dr. Racorean said. “We have legitimate hopes that these quantum computers will help unveil some of the now-hidden mysteries of the Universe.”
