Quantum foundations have been a topic of interest for several decades as they try to describe how quantum mechanics work fundamentally. Quantum mechanics is a theory that explains the behavior of small particles at a sub-atomic level. It has been successful in describing a lot of phenomena within physics, but the theory’s rules deviate from classical mechanics, which explains the behavior of larger objects. For this reason, quantum foundations try to bridge the gap between the two theories, and also answer some questions like wave-particle duality and Schrodinger’s cat.
What is Quantum Foundations?
Quantum foundations are a study of the underlying principles of quantum mechanics. The study has a philosophical aspect to it, as scientists and researchers try to explain how the theory works. Quantum foundations’ goal is to provide a comprehensive understanding of quantum mechanics, which has so far remained elusive, even after decades of research.
For several decades, theorists have approached the foundation of quantum mechanics in various ways. Some focus on the mathematical and technical aspects of the theory, while others focus on the implications of the theory’s principles. Others attempt to find better ways to interpret quantum mechanics by removing some of its apparent paradoxes.
How are Quantum Foundations Used?
For all practical purposes (FAPP), quantum foundations are irrelevant. Almost all engineers and scientists who design computer hardware or build electronic devices do not need to know about quantum foundations to do their jobs. They can rely on quantum mechanics’ cohesive mathematical framework to predict and understand the behavior of physical systems with great accuracy. Therefore, there is no need for them to consider quantum foundations as they do not have direct bearing on daily activities.
This is why scientists keep emphasizing, as mentioned in the question, that quantum foundations are irrelevant in everyday jobs. The invention of the acronym FAPP is to highlight that fact. However, that does not mean that quantum foundations have no practical applications. They are not directly useful in building computers or cars, but they are important in developing new technologies, applications, and theories.
Quantum Foundations in Technology
Quantum mechanics has already led to the development of several novel technologies, such as quantum cryptography and quantum computing. Quantum foundations have been essential in advancing these technologies.
Quantum Cryptography
Quantum cryptography is a method of using quantum mechanics to guarantee secure communication between two parties. The security of credit card transactions that we engage in, internet banking, among other activities, is based on cryptography. Cryptography is a process that makes sensitive data incomprehensible to anyone who does not have the right key to decoding it. This method of protecting data is essential in digital communication.
Quantum cryptography is a much more secure form of cryptography than classical cryptography. It relies on quantum mechanics to generate a shared cryptographic key between two parties. This key is unique to the message and cannot be intercepted by any person. The principles of quantum mechanics underly quantum cryptography, which means quantum foundations are an essential part of this technology.
Quantum Computing
Quantum computing is an exciting advancement that could have massive implications in various fields. The basic idea behind quantum computing is that it can exponentially process information in certain tasks compared to classical computers. The technology works based on quantum bits, referred to as qubits. A qubit is a unit of quantum information that can store a 0 or a 1, as well as all values in between. Qubits can exist in a state called superposition that allows them to explore multiple outcomes simultaneously.
Quantum computing is a rapidly developing technology that has the potential to solve problems that are beyond classical computing. For example, quantum computing can solve problems that require searching a large database or optimizing difficult problems. Faster computers will lead to more efficient data processing, which is useful in various fields like finance, physics, and logistics.
Quantum mechanics has been essential in the development of quantum computing, and quantum foundations play a vital role in understanding and advancing quantum computers.
Quantum Foundations and New Theories
New theories often arise from problems or inconsistencies uncovered in existing theories. These theories allow us to explain new phenomena and predict experimental results. Quantum foundations are essential in creating and recognizing these new theories.
The principles of quantum foundations have led to the development of several new theories, such as the many-worlds interpretation, Bohmian mechanics, and the transactional interpretation. These theories explore the implications of quantum mechanics in different ways, and each has its supporters.
Many-Worlds Interpretation
The many-worlds interpretation postulates the existence of multiple universes, and it is one of the most popular interpretations of quantum mechanics. This theory suggests that the universe is constantly splitting off into different parallel universes, each with different outcomes. According to this theory, if a particle can exist in multiple states simultaneously, then those states exist in multiple parallel universes. The many-worlds interpretation has gained popularity over the years, and some researchers believe that it is one of the best ways to interpret quantum mechanics.
Bohmian Mechanics
Bohmian mechanics is a theory that explains quantum mechanics using the theory of the pilot-wave. According to this theory, there is an underlying “wave function” that guides the behavior of particles. This theory does not rely on the probabilities used in quantum mechanics to explain the behavior of particles. Instead, it uses deterministic laws that rely on initial positions and momenta of particles, as well as the wave function. This theory has seen less support than the many-world interpretation, but it still has its supporters.
Conclusion:
Quantum foundations are not practical to most people’s daily activities. For engineers and scientists designing devices, the principles of quantum mechanics provide all the necessary tools to build functional machines. However, quantum foundations are important in developing new technologies such as quantum computing and cryptography. They are also important in the creation of new theories, which can explain new phenomena and expand our understanding of the universe. As such, quantum foundations have practical applications in developing new technologies, creating new theories, and pushing the boundaries of human knowledge.
