Quantum Information Lab
Design and test protocols at the intersection of information physics and quantum mechanics, where the fundamental nature of reality enables revolutionary communication technologies.
Entangled states: the foundation of quantum communication
From Paradox to Technology
What Einstein dismissed as “spooky action at a distance” has become the foundation of an entirely new form of communication. The 2022 Nobel Prize in Physics celebrated the experimental verification of quantum entanglement—confirming that nature operates in ways that classical physics cannot explain.
Quantum communication leverages the fundamental properties of quantum mechanics—superposition, entanglement, and measurement—to create communication protocols that are not just secure, but provably unbreakable by the laws of physics themselves.
Bell's Theorem in Action
Quantum correlations that violate classical expectations:
Classical physics predicts maximum correlation of 2, quantum mechanics allows 2√2 ≈ 2.83
Fundamental Quantum Resources
Quantum Entanglement
Non-local correlations between particles that remain connected regardless of spatial separation, providing the foundation for quantum key distribution and teleportation protocols.
Quantum Superposition
The ability of quantum systems to exist in multiple states simultaneously until measured, enabling dense coding and parallel information processing capabilities.
No-Cloning Theorem
The fundamental impossibility of perfectly copying unknown quantum states provides intrinsic security—any eavesdropping attempt necessarily disturbs the system.
Quantum Measurement
The act of measurement yields definite outcomes, producing unique information signatures that form the basis of quantum authentication protocols.
Revolutionary Communication Protocols
Quantum Key Distribution (QKD)
Generate provably secure encryption keys using quantum states. Any interception attempt introduces detectable errors, guaranteeing the security of the key exchange process through the fundamental laws of quantum mechanics.
Quantum Teleportation
Transfer the complete quantum state of a particle across arbitrary distances using entanglement and classical communication. The original state is destroyed in the process, maintaining the no-cloning principle.
Dense Coding
Transmit two bits of classical information using a single quantum bit (qubit) plus one classical bit, by exploiting pre-shared entanglement. This protocol demonstrates quantum advantages in communication efficiency.
