What is a quantum computer?

A quantum computer are based on the principles of quantum mechanics for computational and data processing tasks. In contrast to classical computers that rely on bits with values of "0" or "1," quantum computers use qubits (quantum bits) as their fundamental information units. Qubits can exist in a superposition of both "0" and "1," allowing them to represent significantly more information than classical bits. Quantum computers exploit properties such as superposition, coherence, and entanglement from quantum mechanics to facilitate massive parallel processing, a capability not available to classical computers. This enables quantum computers to solve problems with polynomial or exponential speedup.

Quantum computer history in brief

Quantum computing (QC) had its origins in a proposal by Nobel Laureate Richard Feynman in 1981. A significant breakthrough occurred in 1994 when Peter Shor from MIT devised a quantum algorithm capable of exponentially speeding up the process of finding prime factors. Subsequently, in 1996, Lov Grover introduced a quantum database search algorithm, demonstrating quadratic speedup. The practical implementation of quantum computing advanced in 1998 when Isaac Chuang, Neil Gershenfeld, and Mark Kubinec developed the first two-qubit quantum computer capable of performing computations.

Real-World Applications:

Quantum computing is not just theoretical; it's already making an impact in the real world.

Here are some compelling examples:
