Quantum computing is a new type of computing that utilizes quantum mechanics principles like superposition and entanglement. It works by using quantum bits (qubits) that can be 0, 1, or both at the same time. While still in development, quantum computers show promise for solving certain complex problems much faster than classical computers. The document discusses the invention of quantum computing, different types, applications, advantages like speed, and challenges like high error rates.

3. Introduction
What is Quantum Computer?
• Quantum computing is a field of computations
that focuses on the development of computer
technology based on the principles of quantum
theory.
• Quantum computing is a type of computation
that exploits the common properties of
quantum states, such as superposition,
interference and entanglement to performs
calculation

4.  Why is it called Quantum
Computing?
• Quantum computing is the study of how to
use phenomena in quantum physics to
create new ways of computing. Quantum
computing is made up of qubits.
• Qubit can either be 0 and 1 or a
superposition of both 0 and 1

5.  How does it work?
• Quantum computers perform
calculations based on the probability of
an object's state before it is measured -
instead of just 1s or 0s .

11. Disadvantages
• Current quantum computer are largely
prototypes that are still bulky &
complicated.
• They still have many teething problems
that their developer have not yet been
able to fully address.
• The developers of the systems are
struggling with an error rate that is still
far too high.
