Basics and Applications in Quantum Optics
Quantum optics has received a lot of attention in recent decades due to the handiness and versatility of optical systems, which have been exploited both to study the foundations of quantum mechanics and for various applications. In this Special Issue, we collect some articles and a review focusing on some research activities that show the potential of quantum optics in the advancement of quantum technologies
An efficient quantum-classical hybrid algorithm for distorted alphanumeric character identification
An algorithm for image processing is proposed. The proposed algorithm, which
can be viewed as a quantum-classical hybrid algorithm, can transform a
low-resolution bitonal image of a character from the set of alphanumeric
characters (A-Z, 0-9) into a high-resolution image. The quantum part of the
proposed algorithm fruitfully utilizes a variant of Grover's search algorithm,
known as the fixed point search algorithm. Further, the quantum part of the
algorithm is simulated using CQASM and the advantage of the algorithm is
established through the complexity analysis. Additional analysis has also
revealed that this scheme for optical character recognition (OCR) leads to high
confidence value and generally works in a more efficient manner compared to the
existing classical, quantum, and hybrid algorithms for a similar task.Comment: A quantum-assisted algorithm for optical character recognition (OCR)
