INTRODUCTION
Rapidly-emerging technology
that harness of the laws of
quantum mechanics to solve
problems too complex for
classical computer.
Quantum Computer use atoms
to perform calculations
Here computation depends on
principle of quantum theory.

HISTORY
Quantum computing started in the 80s with the idea of using weird
quantum stuff for super-powered computers. In the 90s, scientists
figured out how to give them instructions. Now we're building them
with special atoms, one by one!

BASIC CONCEPTS OF QUANTUM COMPUTING
Weird Qubits: Regular
computers use bits (0 or 1),
quantum uses qubits (0, 1, or
both at once).
Superpower of
Superposition: Imagine a
coin being heads and tails
until it lands - that's a qubit's
power!
Spooky Entanglement: Link
qubits together, and
measuring one instantly
affects the other, no matter
5
the distance!
DIFFERENCE BETWEEN CLASSICAL COMPUTING AND
QUANTUM COMPUTING
Classic Computer Quantum Computer
Bits vs. Qubits 0, 1 0, 1 or both at same time
Speed Slow Super fast for specific
problem
Tasks Every day stuff Specialized problems
Stage Mature Early development
6
APPLICATIONS
Here are some applications of quantum computing:
Artificial Intelligence (AI) and Machine learning
Materials science
Financial modeling
Logistics and optimization
Cryptography

ADVANTAGES
Blazing speed: Solves problems faster than regular computers.
Simulation master: Creates detailed simulations of complex systems.
Optimization guru: Solves tough optimization problems.
Future-proof encryption: Develops unbreakable encryption methods

CHALLENGES OF QUANTUM COMPUTING
Tricky: qubits are super sensitive and hard to control.
Prone to errors: sensitive qubits require complex error correction.
Not all-purpose: great for special jobs.
Limited applications: not a replacement for classical computers, needs
new algorithms.

CONCLUSION
Quantum computing is a game-changer with the potential to solve
problems impossible for regular computers. However, it's still early
days. We need to overcome technical hurdles and develop specific
applications. It won't replace classical computers, but work alongside
them. The race is on to harness this power and adapt to a quantum
future.
