This chapter describes the memory devices in quantum-DNA computing with multi-valued logic system. It discusses combined Quantum and DNA computing for designing different memory devices considering a binary logic system. The chapter discusses combined multiple-valued Quantum and DNA computing and novel theoretical methods for designing different memory devices considering a binary logic system. Therefore, an integrated computing system as multiple-valued Quantum-to-DNA and vice versa for multi-valued 9-to-2 ROM memory is the main concern. For information processing and storing, bits are used as traditional computing systems, qubits in quantum computing, and sequences in DNA computing systems. Multi-Valued ROM consists of two basic components- multi-valued Decoder and multi-valued OR operations. The software can “partition” a portion of a computer's Cache memory, allowing it to act as a much faster hard drive that is called a Cache memory disk.
This chapter reviews the developments in the field of integrated nonlinear photonics. It discusses the use of silicon for integrated nonlinear photonics. The field of integrated photonics grew in parallel with the emergence of optical fiber communications and micro-electronics fabrication. This led to the development of active and passive devices such as diode lasers, optical modulators, and planar light wave circuits consisting of filters, couplers, and multiplexers. Integrated photonics technology has recently begun to impact the quantum optics community, forming a distinct area of research termed quantum photonics. With its capacity for complex large-scale on-chip photonic circuits, integrated quantum photonics has been suggested as a solution to the challenge of scaling increasingly complex quantum optical experiments and devices. Quantum information technologies that explicitly tap into the unique properties of quantum systems are predicted to greatly outperform their classical counterparts.
