Two-way quantum computers (2WQC) adding CPT analog of state preparation to attack NP problems
Jarek Duda (Jagiellonian U.)
Abstract: While one-way quantum computers (1WQC) use reversible, unitary evolution, they treat boundary conditions in asymmetric way: allowing to fix only the initial states by state preparation. There will be discussed their 2WQC enhancement adding CPT analog of such state preparation to also fix some final states with physical constraints – using CPT analogs as e.g. pull/push, negative/positive pressure (e.g. radiation), stimulated emission/absorption enforcing deexcitation/excitation. For hydrodynamics realizations it could be done by just connecting such chip into a circuit with pump: both pushing into with positive pressure, and pulling from with negative pressure. Mathematically hydrodynamics is governed by similar wavelike equation as electromagnetism, hence I will focus on more practical photonic quantum computers, e.g. with (unidirectional) ring laser acting as pump for photons. If successful, thanks to better control of information flow, analogously to Shor algorithm, in theory such 2WQC could attack NP complete problems.
