Secure communication with choice of measurement

TL;DR

This paper proposes a secure quantum communication protocol that encodes information in measurement choices, utilizing measurement outcomes and error correction to enhance security and fault tolerance.

Contribution

It introduces a secure communication protocol based on measurement choices and outcomes, improving upon previous methods that lacked security against eavesdroppers.

Findings

The protocol successfully detects eavesdropping attempts.

Error correction enhances noise resilience.

The method ensures secure information transfer using measurement outcomes.

Abstract

It has been found that the signal can be encoded in the choice of the measurement basis of one of the communicating parties, while the outcomes of the measurement are irrelevant for the communication and therefore may be discarded. The proposed protocol was novel and interesting, but it wasn't secure for communication. The eavesdropper can obtain the information without being detected. We utilize the outcomes of the measurement to propose a secure communication protocol. And the error correction code is used to increase the fault tolerance in the noise.
