Abstract

A new method to hide specific quantum states in a superposition will be proposed. The proposed method is used to hide an encrypted message in a superposition. The process of hiding and unhiding the target quantum states is fast by using a single iteration of the amplitude amplification operators. This makes the message 100% safe by direct measurement from an eavesdropper. No entanglement sharing is required among the communicating parties.
