Qubit and bit-based quantum hybrid secret key generation

Abstract

For the generation of a secret key, hardly a quantum algorithms integrating states and bits have yet developed. Integrating random states and bits is difficult for a combiner component. The underlying problems of the study are the design of a quantum circuit, an algorithm, state polarization setup, and the concatenation of bits and states. By combining either rectilinear, orthogonal (superposition), or both states with bits, we have investigated three different possibilities for the quantum hybrid protocol. We investigated errors in each case and compared them with regard to decoherence and other quantum mechanics properties by taking into consideration the effectiveness of states during transmission time across an untrusted channel. Furthermore, we observed that key size, state errors, design complexity, and security are all addressed in a reasonable manner for identifying solutions while comparing our results to earlier proposed quantum protocols. Because of this, the suggested key protocol's effectiveness is greater than that of earlier proposed protocols.

Beyond Bits: A Review of Quantum Embedding Techniques for Efficient Information Processing

“…To address that challenge, further research is needed to investigate the potential of hybrid quantum algorithms for data fitting, for instance, in [39], [40], [129], [145]. "Hybrid" encoding patterns aim to leverage the advantages of the best appropriate approaches and enhance the representation and manipulation of classical data in quantum states.…”

Secure Communication in Multi-Subnetwork by QKD Protocol with Entanglement and Decoy States

“…A small structure known as a footer or trailer may occur at the end of the frame, which typically only contains information for error-checking. Control information is always included in the header since it is the first component of a packet or frame that a networking device, such as a switch or router [24][25].…”

Multi‐Party Quantum Key Distribution Using Variational Quantum Eigensolvers

“…[11][12][13][14] Other QKD methods include the B92, SARG04, and six-state protocols, which aim to securely distribute keys based on quantum principles. [11,[15][16][17][18][19][20] However, QKD protocols are vulnerable to side-channel attacks, requiring techniques like digital signatures for mitigation. Understanding these protocols helps in exploring advancements that enhance security, improve key rates, and overcome implementation challenges.…”
