Chinese researchers have allegedly made a major breakthrough in Quantum Secure Direct Communication (QSDC). According to reports, the team has developed a new communication protocol that allows secure data transmission using quantum mechanics principles, setting a world record for transmission speed and distance.

In case you are unaware, QSDC is a type of quantum communication that directly transmits information in quantum states (such as photons) without needing encryption keys like traditional methods (e.g., quantum key distribution or QKD).
