Quantum Channel Capacities
Quantum channels form the backbone of quantum communication. Whether it’s distributing entanglement, transmitting qubits, or sending classical information securely, the capacity of a quantum channel tells us how much information….
Quantum Repeaters
Quantum repeaters are critical components in long-distance quantum communication systems. They play a similar role to classical repeaters in fiber-optic networks, but with a key difference: they are designed to….
Security Proofs in Quantum Cryptography
A security proof in cryptography is a formal demonstration that a cryptographic protocol is secure under certain assumptions. In classical cryptography, these assumptions are often based on the hardness of….
Quantum Digital Signatures
Quantum Digital Signatures (QDS) are the quantum analog of traditional digital signatures used in classical cryptography. Their primary purpose is to: Just like pen-and-ink signatures prove authorship, digital signatures prove….
Quantum Oblivious Transfer
Quantum Oblivious Transfer (QOT) is a powerful cryptographic protocol rooted in quantum mechanics. It allows a sender (let’s say Alice) to send information to a receiver (Bob) in a special….
Quantum Coin Flipping
Quantum Coin Flipping (QCF) is a cryptographic protocol that allows two parties—who don’t trust each other—to agree on a random binary outcome (heads or tails, or 0 or 1), using….
Device-Independent QKD
Device-Independent Quantum Key Distribution (DI-QKD) is an advanced form of quantum key distribution that provides the highest level of security, even if the devices used in the protocol are untrusted….
