Quantum encryption

The computers we use today are based on binary values ( “bits” )representing a value of either 0 or 1. However, quantum computers use a quantum bit ( “qubit” ), which uses a property of sub-atomic particles to maintain (or “superpose”) different states at the same time. This means a qubit can be both 0 …
