Quantum Teleportation
Quantum teleportation is one of the most fascinating phenomena in quantum mechanics. Despite the science-fiction name, it doesn’t involve transporting matter or people from one place to another. Instead, it….

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….
E91 Protocol
The E91 Protocol is a Quantum Key Distribution (QKD) method proposed by physicist Artur Ekert in 1991. It was a significant development in quantum cryptography because it uses quantum entanglement….
Photonic Quantum Computing
Photonic quantum computing uses particles of light, known as photons, to carry and process quantum information. Instead of using physical matter like electrons or ions, it harnesses the unique quantum….
Qubits and Quantum States
In classical computing, we rely on bits — tiny switches that are either off (0) or on (1). Every digital device you use operates using billions of these bits. But….
