Role of optics in super-fast information processing

Abstract

From the decade of seventy a motivation inspired the people of optical and computing community for using optics in place of electronics as information carrying signal in digital data and image processing. Here in this communication the author extends a brief report on the role of optics in super fast computation and its advantages.

Implementation of all‐optical Pauli‐Y gate by the integrated phase and polarisation encoding

“…Quantum logic system can ensure a new vista for fast and secured computation and data processing due to some of its salient features like reversibility, large storage capacity, high degree parallelism and so on [1][2][3][4]. Several well-known optical logic gates and quantum gates (like Hadamard gate, Toffoli gate, quantum NOT gate, Fredkin gate etc.)…”

Approach of implementing phase encoded quantum square root of NOT gate

“…Introduction: Optics is very much advantageous in computation and communication for its superfast speed, inherent parallelism and noise-reduced operation [1]. Quantum logic system may disclose a new vision for fast and secured computation and data processing in future due to some of its salient features such as reversibility, large storage capacity, highly parallelism [2,3].…”
