Quantum Computer is the latest trending topic in the tech industry. Here are 20 Facts about Quantum Computers that you need to know to get a better understanding of Quantum Computers.

Quantum Computers Facts:

1. Physicist Richard Feynman first proposed the concept of a quantum computer in 1982.
2. Canadian physicist David Deutsch and Australian physicist Richard Jozsa developed the first quantum algorithm in 1992.
3. Quantum computers are a type of computing device that uses the principles of quantum mechanics to perform complex calculations.
4. Quantum computers use quantum bits or qubits, which can exist in a superposition of both 0 and 1 states simultaneously.
5. Superposition is a fundamental property of quantum mechanics that allows qubits to hold multiple values at once. Quantum computers can perform certain calculations exponentially faster than classical computers because of superposition.
6. Quantum computers also utilize another quantum phenomenon called entanglement. This phenomenon allows qubits to be highly marked up with each other, even when they are separated by large distances.
7. One of the most famous quantum algorithms is Shor’s algorithm, which efficiently factors large numbers and poses a significant threat to traditional cryptographic methods, such as RSA.
8. Sophisticated cooling systems are used to control the temperature as Quantum computers require extremely low temperatures (near absolute zero) to maintain the delicate quantum states of qubits.
9. Quantum error correction techniques are being developed to mitigate the errors caused by Decoherence, which is the loss of quantum information.
10. The term “Quantum Supremacy” refers to the point where a quantum computer can solve a problem that is practically impossible for the most powerful classical supercomputers.

More Facts about Quantum Computer:

1. Various fields like Cryptography, drug discovery, optimization problems, and artificial intelligence can be revolutionized by Quantum Computers.
2. Building reliable and scalable qubits is one of the biggest challenges faced by researchers.
3. Quantum computers have the potential to accelerate machine learning algorithms, leading to advancements in AI applications.
4. In 2019, Google claimed to have achieved quantum supremacy when their 53-qubit quantum computer solved a specific problem in 200 seconds, which they estimated would take the world’s most powerful classical supercomputers around 10,000 years to solve.
5. Quantum computers can be categorized into different types, such as superconducting qubit-based quantum computers (e.g., those developed by IBM and Google), trapped-ion quantum computers (e.g., those developed by IonQ and Honeywell), and topological qubit-based quantum computers (e.g., those developed by Microsoft).
6. Quantum computers are expected to have a significant impact on the field of materials science, allowing for the simulation of complex quantum systems and the discovery of new materials with desirable properties.
7. Major tech companies, such as IBM, Google, Microsoft, Intel, and others, are actively investing in quantum computing research and development.
8. The study of quantum computing is interdisciplinary, involving quantum physics, computer science, and information theory.
9. Quantum computers are not intended to replace classical computers. But rather to complement them for specific tasks that are challenging or impossible for classical systems.
10. Quantum computing is still an active area of research. It’s difficult to predict precisely when practical, large-scale quantum computers will become a reality. However, progress in recent years has been promising, and technology holds tremendous potential for the future.
