Quantum computers can solve complex problems beyond the capabilities of classical computers
Quantum computers have the potential to solve complex problems beyond the capabilities of classical computers. This is because quantum computers can process information much faster than classical computers. Classical computers use binary bits (0 or 1) to process information, whereas quantum computers use quantum bits, or "qubits", which can exist in a superposition of states, meaning they can be 0 and 1 at the same time. This allows quantum computers to perform some calculations much faster than classical computers.
The ability of qubits to exist in multiple states simultaneously gives them the capacity to handle a much larger amount of information at a faster speed than classical computers. This makes quantum computers particularly well-suited for solving complex, data-heavy problems, especially those that utilise machine learning. For example, quantum computers have been used to achieve rapid DNA sequencing in medicine and precisely predict future traffic volumes in transportation.
Quantum computers can also be used to develop more accurate and efficient machine learning algorithms for applications such as image and speech recognition, which can be beneficial for companies developing AI technology. Additionally, quantum computers could be used to simulate the behaviour of complex quantum systems, which has applications in chemistry, material science, drug discovery, and forecasting.
Furthermore, quantum computers could solve optimisation problems more efficiently than classical computers, with applications in logistics, finance, and supply chain management. They could also improve cybersecurity by enabling the development of new cryptographic protocols, and they could even help us understand biology and evolution, cure cancer, and take steps to reverse climate change.
While quantum computers have the potential to solve complex problems, they are still in the early stages of development and there are challenges to be addressed before they can become widely adopted. However, the significant investments being made in the quantum computing space and the rapid advancements in the field indicate a bright future for this technology and its potential to revolutionise various sectors.

Quantum computers can process information faster than classical computers
Classical computers use bits, binary units of information, to perform calculations. Bits can be either 0 or 1. Quantum computers, on the other hand, use quantum bits, or qubits, which can exist in a superposition of states, meaning they can be 0 and 1 at the same time. This allows quantum computers to perform multiple calculations simultaneously, giving them an exponential computational advantage over classical computers.
In late 2019, Google claimed to have solved a problem in 200 seconds with a quantum computer that would have taken the world's fastest supercomputer 10,000 years. This demonstrates the potential for quantum computers to process information at a much faster rate than classical computers.
The basic unit of information in quantum computing, the qubit, serves the same function as the bit in classical computing. However, unlike a classical bit, which can be in one of two states (0 or 1), a qubit can exist in a superposition of its two "basis" states, meaning it is in both states simultaneously. This property of qubits is what enables quantum computers to perform calculations much faster than classical computers.
In addition to superposition, quantum computers also utilise quantum entanglement. When qubits become entangled, changes to one qubit directly affect the other, allowing for much faster information transfer between qubits.
While quantum computers have the potential to process information much faster than classical computers, it is important to note that they are not universally faster. Classical computers are still better suited for certain tasks, such as simple arithmetic and text processing. Quantum computers excel in areas such as machine learning, cryptography, and modelling financial markets.
The field of quantum computing is still in its early stages, and there are several challenges to be addressed before quantum computers can become widely adopted. However, the potential for faster information processing has attracted significant investment from major tech firms and investors, who recognise the possible applications in various industries.

Quantum computers can be used to develop new cryptographic protocols
Quantum computers are a relatively new type of computer programming that incorporates quantum mechanics into a machine's functionality. Quantum computers have the potential to be significantly more powerful than classical computers, which has led to a surge of interest in quantum computing stocks. Quantum computers can be used to develop new cryptographic protocols, also known as quantum encryption.
Quantum encryption is based on the laws of physics, specifically the principles of quantum mechanics. It relies on the fact that particles are inherently uncertain and can exist in multiple states at the same time. This means that it is impossible to predict their exact quantum state, making it an ideal basis for encryption.
Another principle of quantum mechanics that can be used for encryption is that a quantum system cannot be measured without being altered. According to the laws of quantum physics, measuring or observing a quantum system will always have a measurable effect on that system. This means that if someone tries to intercept an encrypted message, the intended recipient will always be able to detect it.
Quantum encryption also takes advantage of the fact that photons, the smallest particles of light, can be set to have specific polarities or spins, which can serve as binary counterparts for the ones and zeros of classical computational systems.
While quantum encryption is still in its early stages, it has the potential to be far more secure than previous types of cryptographic algorithms and is even theoretically unhackable. As quantum computers become more powerful and common, it is important to develop new forms of cryptography to protect sensitive data. This is why people are investing in quantum computers and working to develop quantum-safe cryptography.
