The field of Quantum Information Science is the most challenging and hot topic among all branches of science. This field is also quite interdisciplinary in character, and people from quantum theory, computer science, mathematics, information theory, condensed matter physics, many-body physics and many more have been a…

The emergence of quantum computing presents unprecedented challenges for cybersecurity professionals and organizations, requiring fundamental reconceptualization of cryptographic security paradigms. Despite widespread technical awareness of quantum threats, o…

This paper proposes a unified theoretical framework that maps the Gravitational Spinor (GS) theory from quantum gravity onto the study of artificial intelligence consciousness through mathematical analogy. It constructs a three-tiered nested principal fiber b…

We introduce a configuration-dependent parametrisation of coherence in Wheeler’s delayed-choice experiment based on the complex quantity T = t ? i τ . The real component t retains its usual causal role, while the imaginary component τ encodes the attenuation…

The author has recently presented the Single-Iteration Quantum Search Algorithm, which achieves amplitude-amplification with exactly one oracle call and one π/4 rotation [1] . For N = 2 n search spaces, the algorithm achieves success probability exactly 1/2 w…

I derive the quantum mechanical prediction − a · b for the singlet spin state using local measurement functions within the Space-Time Algebra (STA) framework. I establish a compact and computationally tractable STA representation of the two-particle singlet s…

Quantum cybersecurity has emerged as a critical strategic issue at the intersection of national security, technological advancement, and digital sovereignty. As quantum computing technology advances toward practical implementation, the dual-edged nature of th…

This paper presents the Single-Rotation Quantum Search Algorithm, which achieves amplitude-amplification with exactly one oracle call and one rotation operation. We prove that for unstructured search over N items, a single rotation by π/4 radians is both nece…

Grover’s algorithm achieves O ( N ) query complexity for unstructured search, a result proven optimal by Zalka for algorithms using a fixed oracle operator. This paper presents the Exponential Speedup Algorithm, a modified amplitude amplification algorithm th…

This paper proposes a quantum algorithm for solving the tautology and the satisfiability problems for a Boolean formula. Let’s say we are given a Boolean formula. The variables of the Boolean formula can take only two values—TRUE or FALSE. The tautology probl…

Oracle-based quantum algorithms cannot use deep loops because quantum states exist only as mathematical amplitudes in Hilbert space with no physical substrate. Critically, quantum wave functions are inherently self-destructive. Quantum information must comple…

Authors submit their manuscript, metadata, and declarations through the portal. There is no submission fee.
The editorial office screens the manuscript for scope, completeness, and formatting before assigning a handling editor.
At least two independent reviewers evaluate the manuscript under single-blind review. Where revisions are required, authors respond point by point.
On acceptance the article processing charge is invoiced and the CC BY 4.0 copyright handover is signed.
The article is copyedited, typeset, and given a DOI, then publishes open access with a permanent link.
Manuscripts must be original and not under consideration elsewhere. Submit in Microsoft Word or LaTeX with figures at 300 dpi minimum. Structure research articles as Abstract, Introduction, Methods, Results, Discussion, and References.
Use the journal's numbered (Vancouver) reference style. Cite sources consecutively in the order they appear, and ensure every reference is complete and retrievable.
