Physical Principles: Superposition Quantum computing and computers involve a variety of physical principles one of which is superposition at the quantum level. Superposition is essentially the ability of a quantum computer or system to be in multiple states at the same point of time. In other words, something can be “up” and “down,” or “here” and “there” at the same point of time. In quantum computing superposition implies that a qubit can be in combination of two states 0 and 1: ψ = a 0 + b 1. ϕ ϕ ϕ ϕ It’s the superposition of qubits that gives quantum computers their inherent parallelism. This parallelism allows quantum computers to work on a million computations at a time [1]. It requires us to assume that between these states there exist peculiar relationships such that whenever the system is definitely in one state we can consider it as being partly in each of two or
