1. Introduction

The advent of quantum computing heralds a transformative era, promising to reshape the landscape of business and technology in profound ways. Beyond the allure of quantum computing’s capabilities, it is essential to navigate the ethical and socioeconomic considerations it introduces. As businesses grapple with harnessing this formidable technology, questions of data privacy, economic disparities, labor market transformations, and environmental impact come to the fore.

2. Background of Quantum Computing

The field of quantum computing is often hailed as the next frontier of technological innovation. Its promise stems from the unique and often counterintuitive principles of quantum mechanics, a theory of physics that describes the behavior of particles at the smallest scales, namely atoms and subatomic particles. The foundation of quantum computing revolves around three main principles: superposition, entanglement, and quantum interference.
Classical computers, which have driven much of the modern digital revolution, operate on bits that can be either 0 or 1. These bits form the basis of all data processing in conventional machines [1]. In contrast, quantum computers use quantum bits or qubits. Unlike classical bits, qubits can exist in a state of superposition, where they are simultaneously both 0 and 1. This capability exponentially increases the computing power of quantum machines. For example, while two classical bits can be in one of four possible states at any given time, two qubits can represent all four states simultaneously [2].
Entanglement, the second cornerstone of quantum computing, is a quantum phenomenon where particles become interlinked in such a way that the state of one particle directly affects the state of another, regardless of the distance between them [3]. This means that qubits that are entangled can communicate and coordinate in a manner that classical bits cannot, allowing quantum computers to solve problems that are currently beyond the reach of classical machines.
The third essential principle is quantum interference, a phenomenon in which the probability amplitudes (the coefficients that describe the state of a quantum system) combine in such a way as to reinforce or cancel each other out. This allows quantum algorithms to amplify correct solutions and minimize errors, leading to faster and more accurate computations [4].
The idea of a quantum computer was first conceptualized by Richard Feynman in the early 1980s. Feynman postulated that simulating quantum systems on a classical computer was inherently inefficient and suggested that a quantum mechanical computer would do the job more effectively [5]. Following Feynman’s proposal, in 1985, David Deutsch of the University of Oxford formulated the framework for the universal quantum computer, marking a major theoretical foundation for the field [6].
The transition from these theoretical foundations to tangible machines took decades of research and innovation. Quantum computing, initially only a topic of academic exploration, has in recent years seen significant investments from major tech corporations like IBM, Google, and Intel. These companies are drawn by the potential of quantum computers to solve problems deemed infeasible for classical machines, such as simulating large molecules for drug discovery or optimizing vast logistical networks in real-time [7].
Quantum computing is set to redefine the boundaries of what is computationally possible. Rooted in the enigmatic principles of quantum mechanics, it offers a paradigm shift from the classical computing models that have dominated the digital age.

In the late 1990s and early 2000s, IBM made notable strides in quantum computing research, cultivating strong academic–corporate partnerships [8]. Their endeavors began to bear fruit, and in 2019, the company unveiled its IBM Q System One, marketed as the world’s first integrated quantum computing system designed for scientific and commercial use [9].
Google, another behemoth in the tech industry, entered the quantum arena with zeal. In 2019, the company claimed a significant milestone by achieving “quantum supremacy”. This event marked the first instance where a quantum computer performed a specific task faster than the world’s best classical computer. Google’s 53-qubit Sycamore processor took a mere 200 s to perform a calculation that would have taken a state-of-the-art supercomputer approximately 10,000 years [10].
Intel, renowned for its semiconductor- and chip-making expertise, is also deeply entrenched in the quantum race. In 2018, the company showcased a 49-qubit quantum chip, named “Tangle Lake”, emphasizing its commitment to scaling up quantum hardware [11].
