In recent decades, technology has rapidly advanced, and advancements in quantum computing have drastically shifted the computing landscape. Capable of performing certain calculations exponentially faster than classical computers, quantum computers show many promising applications across various disciplines of science and technology. From drug production to solving complex optimization problems, the power of quantum computing is revolutionizing the way we interact with technology and understand the world.
What is Quantum Computing?
In conventional computing, information is represented and stored in terms of binary digits (bits) of 0s and 1s. Quantum computing takes computing to the quantum level, where a qubit (quantum bit) can exist as both 0 and 1, a phenomenon known as quantum superposition. This enables quantum computing to take a completely different approach to performing calculations, by computing all possibilities at once instead of consecutively like with classical computers.
By combining some of the principles of quantum theory, quantum computers are able to work with multiple parameters simultaneously, allowing them to exponentially increase the computational power available at our fingertips.
What is the Difference Between Classical and Quantum Computing?
The fundamental difference between classical and quantum computing can be summarized as follows:

Classical computing uses bits with a state of 0 or 1, while quantum computing uses qubits which exist as a superposition of both simultaneously.

Classical computing performs calculations sequentially, while quantum computing does it all at once.

Classical computing is bounded by the laws of classical physics, while quantum computing is partially bound by the laws of quantum mechanics.
Quantum Advantage
Quantum computing offers immense potential for improving a range of applications from finance to drug discovery. This “Quantum Advantage” can be thought of as the extra power of quantum computing when solving certain problems that would be impossible to solve with classical computing.
The following are some of the issues where quantum computing can offer a major advantage:

Searching for Values: Quantum algorithms like Grover’s can search large databases of values in much faster time than their classical counterparts.

Integer Factorization: Quantum algorithms like Shor’s can factor large integers into prime numbers much faster than their classical counterparts.
