Quantum computing is an alternative way to solve complex problems using quantum mechanics, a rapidly emerging technology that has infinite potential in physics and engineering. In quantum computing, quantum is the smallest possible discrete unit of real property, which generally refers to the properties of atomic or subatomic particles such as electrons, neutrinos, and photons. Instead of 0s and 1s, quantum computing uses quantum bits. Just as bits are primitives of information in classical computing, qubits (quantum bits) are primitives of information in quantum computing. For example, bits or binary numbers can have 0 or 1, whereas qubits can have 0, 1, or a quantum superposition of 0 and 1. Quantum computing is a very efficient method because, for some computational tasks, quantum computing provides exponential speedups. This speedup is possible due to three phenomena in quantum mechanics: superposition, interference, and entanglement.
For some methods of storing qubits, the device storing the qubits is kept at a temperature just above absolute zero to maximize aggregation and reduce interference. Another type of qubit storage uses a vacuum chamber that helps to minimize vibration and stabilize the qubits. Furthermore, various methods can signal qubits, including microwaves, lasers, and voltages.
Even though quantum computing does not always dominate classical computing, there are several areas in which it can significantly influence. Because security is essential in all cyber fields, encryption cannot be missed. Traditional cryptography, such as the popular
Rivest-Shamir-Adleman (RSA) algorithm, which is widely used to secure data transmission, relies on intractable problems such as prime factorization or discrete logarithms. Many of these problems can be solved more efficiently using quantum computers.
Quantum computing is still lacking in many ways and is a complicated area to fully use. However, quantum computing also breaks the speed or limit that cannot be reached with conventional computing methods. Ultimately, Quantum computing is a complex and sophisticated method, but if commercialized and demonstrated in many areas of society, it will show infinite growth in the future.
