1. Introduction
Quantum mechanics, a science that emerged in the early twentieth century, underwent a slow incubation of concepts and development throughout the century. Its notable applications include transistors, lasers, magnetic resonance, and electronic microscopes, leading to remarkable technological developments as a result of the research. However, the field did not take a fundamental step toward technological development until Richard Feynman’s statement
[1] that quantum systems could perform a type of computational processing unachievable by classical systems. By exploiting the central properties of quantum mechanics, such as superposition and quantum entanglement, a new development trend has emerged, resulting in real-world applications ranging from cryptography, novel communication systems (teleportation), and quantum processors.
From Quantum Mechanics Toward a Quantum Industry
The emerging areas of quantum information, communication, and processing are no longer confined to physicists, mathematicians, and computational scientists. Instead, these fields increasingly influence various disciplines that address complex phenomena, including chemistry, biology, economics, and even sociology. As a result, a new generation of professionals with varied interests and an inclination toward innovative scientific solutions is being called upon to contribute to develop quantum technologies and solutions.
Based on a classification agreed upon by several authors for the evolution of quantum technologies and the role of education
[2],
Figure 1 shows the three outstanding branches in applied quantum information, quantum processing (quantum computation and algorithmic processing), quantum sensing (measurement, metrology, and quantum sensor development), and quantum communication (quantum processes to generate, store, transmit, and receive quantum information). The diagram highlights emblematic applications in each branch and the classically associated disciplines where professionals are likely to originate.

Nowadays, quantum mechanics courses for physicists and mathematicians have been transformed into a diversity of courses with remarkable specialization, such as Information, Communication, Measurement, and Processing
[3]. The audience has also changed with students coming from several science and engineering programs, including Computer Science, Chemistry, Chemical Engineering, Material Sciences, Nanotechnology, and Electronic Engineering
[4]. Another trend is an exponential increase in educative resources provided by the Internet, such as video conferencing systems, diversified digital learning resources, and specialized tools
[5][6]. Due to these, science has a charming attraction that was hidden before. Those public and innovative resources are reaching young people interested in research, with different focuses based on their academic interests. Students’ increasing interest in science has been sparked by the Internet and the perception of having greater job security than other sectors
[7]. Unfortunately, students’ interest in science does not guarantee their automatic selection of a career in Science or Technology, so additional interventions should be made
[8]. In any event, it can be said that the Internet is facilitating things previously popularized in specialized books. Science is becoming more open and approachable.
2. Quantum Information as an Attractive Life Plan for the Development of Quantum Industry
The boom in quantum information development has been sparked by its perceived potential impact on human society and the undeniable boost that the Internet has provided through scientific dissemination to everyone using their devices. The Internet has generated an intangible impulse for scientific development in the last 25 years, attracting and involving new human resources in research
[9].
After decades of theoretical and experimental work, quantum technologies are a reality, currently crossing a period of emerging growth in a well-identified global industry. Although the most notable goal is the creation of a quantum processing device emulating and improving the capabilities of current computing technologies, other developments are proceeding from different fronts, including quantum processing algorithms, user interfaces with these technologies, the development of quantum sensors, and the associated metrology to measure related systems
[10]. These are commonly classified into three significant developments, computing and simulations, communication and networks, and quantum sensors and measurements. Blocks of countries in North America, Europe, and Asia, have detailed medium-term strategies, roadmaps, and prioritized investments in those technologies as a line of economic development
[11].
As a result, the quantum industry is growing exponentially, transitioning from quantum mechanics, as noted in several prospective references
[4][11][12][13].
Figure 2 schematically shows the exponential growth as a function of time, estimated by research discovery facts and data. The color code marks three different, well-stated developmental stages of that industry. The horizontal axis divides the quantum revolution since its dawn in 1900 (with the Max Planck hypothesis of quanta) as the beginning of quantum science (blue), going through the era of electronics with the development of the semiconductors around the 1960s marking the beginning of the quantum technology stage (orange). Then, the beginning of the quantum industry era (green) was marked by the first commercial quantum computer available, the D-Wave, and 2030 is a planned horizon in the roadmaps of several countries blocks
[12]. Vertical legends refer to applications that appeared or are expected to appear in each stage
[4][11][12][13]. The vertical axis indicates the number of quantum scientists involved in the field; mainly, the number of new employments related to quantum information in the current decade ranges in the tens of thousands yearly
[14]. Otherwise, the leading global industries currently have employees ranging in the millions
[15]. Those values barely set the number of people involved for each stage of the vertical axis, especially for the quantum industry.

Thus, by surpassing the theoretical and basic experimentation of the last century, quantum science is evolving first in the current intermediate stage of quantum technologies to arrive in the following decades in a global industry of quantum applications
[13]. In the future, several applications are expected to be developed involving an increasing number of professionals
[16].
3. Quantum Information Education: A Wider Initiative around the World
The attraction of new human resources to forge and promote disciplines, such as quantum information, requires early actions. Thus, STEM (Science, Technology, Engineering, and Mathematics) educative initiatives provide early approaches for their inclusion
[12]. Those initiatives seek to include, attract, and train students in scientific research first, and then the areas of quantum information as motivating life plans. Quantum information can promote and contribute to scientific interest because it is a disruptive discipline
[2]. Nowadays, specialized groups and institutes use this approach to introduce this discipline in early courses, attracting students through workshops, professional stays, scientific graduate courses, and academic degrees
[3][4][12].
The quantum industry comprises an emerging, commercial, and scalable development of quantum technologies
[2]. The industry has produced massive products and services, such as quantum cryptography devices. Such an effervescent development of potential products and services requires a plethora of qualified human resources for their development and implementation
[17][18]. Today, many commercial initiatives are already developing and improving existing quantum technologies in fierce competition. Thus, IBM, Google, D-Wave, and Amazon Braket are emerging pioneers in developing quantum processors. Meanwhile, MagiQ, AgilPQ, Anametric, and QuantumXchange develop applications and quantum encryption devices. In a disruptive direction, Atom Computing, EeroQ, and IonQ develop solid-state-based processors. ColdQuanta develops various quantum devices for communications and storage. Those companies are examples of quantum products’ accelerated development and commercialization as part of an emerging market on which several developed countries partially bet their global leadership and economy
[11][16].
Those opportunities in the scientific profession have motivated the development of this type of learning experience and training in research for Higher Education students
[19]. However, in each country, it is usual that only a few university education institutions or research centers offer such a possibility, being regularly far from potential candidates. How to attract them? Which initiatives can be formulated to make this opportunity equitable? We can appreciate quantum information’s importance as a discipline in different countries in many educative initiatives implemented in several levels of education. For instance, some experiences introducing the teaching of quantum optics have been reported in secondary education
[20], together with more theoretical approaches teaching Dirac notation
[21]. In high school, an experience teaching quantum computation has been reported
[22], just in the preamble of higher education. Interestingly, such experiences also include technical education regarding Photonics
[23].
Higher Education has many examples of educational initiatives in quantum information and Photonics. Creation of complete educative modules or courses has several implementation examples
[24][25], or at least its inclusion in other courses
[26]. Photonics initiatives are an essential applied area of education, with centers created for the discipline
[27][28][29][30]. All those efforts are directed towards developing leadership in quantum technologies
[31].
