About Quantum Computing:

• It is an area of computer science focused on the development of technologies based on the principles of quantum theory.
• Quantum theory explains the behaviour of energy and material at the atomic and subatomic levels.
• It is based on the principles of the superposition of matter and quantum entanglement and uses a different computation method from the traditional one.
• Quantum computers have the capability to sift through huge numbers of possibilities and extract potential solutions to complex problems and challenges. 
• How does it work?
  • Where classical computers store information as bits with either 0s or 1s, quantum computers use qubits.
  • While classical bits always represent either one or zero, a qubit can be in a superposition of one and zero simultaneously until its state is measured.
  • In addition, the states of multiple qubits can be entangled, meaning that they are linked quantum mechanically to each other. 
  • Qubits can be made by manipulating atoms, electrically charged atoms called ions, or electrons, or by nanoengineering so-called artificial atoms, such as circuits of superconducting qubits, using a printing method called lithography.

 What is Superposition and Entanglement?

• They are two features of quantum physics on which quantum computing is based. 
• They empower quantum computers to handle operations at speeds exponentially higher than conventional computers and with much less energy consumption.
• Superposition:
  • A qubit places the quantum information that it contains into a state of superposition. 
  • This refers to a combination of all possible configurations of the qubit. 
  • Groups of qubits in superposition can create complex, multidimensional computational spaces. 
  • Complex problems can be represented in new ways in these spaces.
• Entanglement:
  • Pairs of qubits can be made to become entangled. 
  • This means that the two qubits then exist in a single state.
  • In such a state, changing one qubit directly affects the other in a manner that's predictable.
  • Quantum algorithms are designed to take advantage of this relationship to solve complex problems. 
  • While doubling the number of bits in a classical computer doubles its processing power, adding qubits results in an exponential upswing in computing power and ability.
