Quantum repeaters, definitely the Holy Grail?!

Quantum repeaters holds the promise of revolutionizing secure data transmission by leveraging the principles of quantum mechanics. Unlike classical communication, which relies on the transmission of classical bits (0s and 1s), quantum communication utilizes quantum bits or qubits, which can exist in multiple states simultaneously due to superposition and entanglement. However, despite its potential, quantum… Continue reading Quantum repeaters, definitely the Holy Grail?!

E91 Protocol: Harnessing Entanglement for Secure Communication

In the rapidly evolving landscape of quantum information science, the pursuit of secure communication has led to groundbreaking developments, one of which is the E91 protocol. Named after its inventors Artur Ekert, Anton Zeilinger, and Alain Aspect, the E91 protocol is a quantum key distribution (QKD) scheme that exploits the unique phenomenon of quantum entanglement… Continue reading E91 Protocol: Harnessing Entanglement for Secure Communication

BB84 Protocol: Quantum Key Distribution for Unbreakable Communication

In the realm of secure communication, the BB84 protocol stands out as a groundbreaking achievement in the field of quantum key distribution (QKD). Proposed by Charles Bennett and Gilles Brassard in 1984, the BB84 protocol leverages the principles of quantum mechanics to enable the exchange of cryptographic keys in a manner that is theoretically immune… Continue reading BB84 Protocol: Quantum Key Distribution for Unbreakable Communication
