Quantum Computing and Blockchain in Business
By :
Quantum computing has quantum bits called qubits (pronounced cue-bit) as their fundamental unit. In the classical computing world, bits take 0 and 1 states. Qubits exist in these two states, but also in a linear combination of both these states called superpositions.
Superpositions can solve some problems faster than the deterministic and probabilistic algorithms that we commonly use today. A key technical difference is that while probabilities must be positive (or zero), the weights in a superposition can be positive, negative, or even complex numbers.
The other important quantum mechanics principle that is fundamental to understanding quantum computers is Entanglement. Two particles are said to display entanglement if one of the two entangled particles behaves randomly and informs the observer how the other particle would act if a similar observation were made on it.
This property can be detected only when the two observers compare notes. The...
