Quantum Computing

  QUBITS - SUPERPOSITION - ENTANGLEMENT - CORRELATION - COHERENCE

 

   QUANTUM COMPUTING works with subatomic particles called QUBITS (quantum bits)

Qubits can represent 0 or 1 or both simultaneously – in a state called SUPERPOSITION

             |0>   or  |1>  or  SUPERPOSITION

Qubits in superposition can become ENTANGLED. Entanglement is an extremely strong CORRELATION that exists between quantum particles. As the number of entangled qubits increases the number of correlations grows exponentially.  Entanglement and correlation allow multiple states to be acted on simultaneously

             For n qubits there are 2n correlations

This is what gives quantum computing its unprecedented speed, capacity and world changing computing potential.

COHERENCE is the force that allows quantum particles to perform together. Factors in the environment like heat and even observation can cause quantum computers to loose stability over time. Existing quantum computers use cold and carefully controlled environments to prevent DECOHERENCE.
