The Rise of Quantum Computing in 2025

What is Quantum Computing?

Quantum computing is a new type of computing that uses the principles of quantum physics to process information. traditional computers use bits (0s and 1s) to store data. quantum computers use quantum bits or qubits. These qubits can be both 0 and 1 at the same time. They allow quantum computers to solve certain problems much faster.

Quantum computing has the potential to revolutionize fields like cryptography, medicine, and artificial intelligence because it can handle complex calculations that are difficult or impossible for regular computers to perform.

Do You Know : The global quantum computing market was valued at approximately USD 472 million in 2021 and is expected to reach USD 4.8 billion by 2027.

Terminologies Used in Quantum Computing

1. Qubit

A qubit can exist in a state of 0, 1, or both simultaneously (superposition). Imagine a spinning coin that can be both heads and tails at the same time until you observe it. That’s like a qubit being in a state of 0 and 1 simultaneously.

2. Superposition

The ability of a qubit to be in multiple states at the same time. If you have a qubit in superposition, it’s like having a light switch that is both on and off simultaneously until you check its state.

3. Entanglement

A phenomenon where two or more qubits become interconnected. The state of one qubit instantly influences the state of the other. If you have two entangled qubits, changing the state of one qubit will instantly change the state of the other, even if they are on opposite sides of the world.

4. Quantum Gate

The quantum equivalent of a classical logic gate. Quantum gates manipulate qubits using quantum operations. A common quantum gate is the Hadamard gate, which puts a qubit into a superposition state. If a qubit is initially in state 0, applying a Hadamard gate will put it into a state that is a mix of 0 and 1.

5. Quantum Circuit

A sequence of quantum gates is arranged to perform a specific computation. For example, A simple quantum circuit uses a Hadamard gate followed by a CNOT gate to entangle two qubits. This can be used as a basic building block for more complex quantum algorithms.

6. Measurement

The process of observing the state of a qubit. They cause it to collapse into one of the basis states (0 or 1). If you measure a qubit in superposition, it will collapse to either 0 or 1.

7. Quantum Algorithm

A step-by-step procedure for solving a problem using a quantum computer. Shor’s algorithm is a famous quantum algorithm that can factor large numbers exponentially faster than the best-known classical algorithms.

8. Quantum Supremacy

The point at which a quantum computer can perform a computation faster than the most powerful classical computers. In 2019, Google claimed quantum supremacy by using their quantum computer to solve a problem in 200 seconds that would take the best classical supercomputers 10,000 years to solve.

9. Decoherence

The loss of quantum coherence. it causes a qubit to lose its quantum state. Imagine trying to keep a delicate balance on a tightrope while people keep bumping into you. The interactions with the environment cause you to lose your quantum state.

10. Quantum Error Correction

Techniques used to protect quantum information from errors due to decoherence and other quantum noise. Quantum error correction codes can be used to detect and correct errors in quantum computations, much like error correction in classical data transmission.

Facts : IBM's Quantum Hummingbird processor, released in 2020, has 65 qubits.

Why Do We Need Quantum Computing?

Quantum computers can process complex calculations much faster than classical computers. This is because they can handle multiple possibilities at once. Imagine trying to find the fastest route through multiple cities. A classical computer checks each possible route one by one, which can take a very long time if there are many cities. A quantum computer can check all routes simultaneously.

Some problems are so complex that classical computers take an impractical amount of time to solve them. Breaking modern encryption codes is extremely difficult for classical computers and could take millions of years. Quantum computers can potentially break these codes in a fraction of the time, which is why they are important for cybersecurity.

Classical computers struggle to simulate quantum systems because they are inherently quantum. Quantum computers, on the other hand, are well-suited for this task. In drug discovery, scientists need to simulate the behaviour of molecules to find new drugs. Quantum computers can simulate these molecules more accurately and quickly, speeding up the discovery of new medications.

Many real-world problems involve finding the best solution among many possibilities, such as optimizing supply chains, financial portfolios, or manufacturing processes.
