Quantum Teleportation Leaps Forward with Integrated Light States

13.12.2025 by Ray Dalio

The fidelity of coherent state teleportation, quantified by $F^{(\gamma)}_{\mathrm{ECS}}$, degrades with increasing coherent-state and squeezing amplitudes, ultimately approaching the $2/3$ classical limit-a fundamental constraint imposed when utilizing unpurified entangled resources for quantum state transfer.

Researchers have demonstrated a complete system for creating, refining, and utilizing complex light states to achieve high-fidelity quantum teleportation, pushing beyond the limits of classical physics.

Shielding Quantum Secrets: A New Defense Against Light-Injection Attacks

13.12.2025 by Ray Dalio

An optical fuse safeguards quantum key distribution systems against light-injection attacks by leveraging the properties of micro-ring resonators and the plasma refractive effect within titanium dioxide waveguides; during a resonant attack, the induced blue shift attenuates the malicious signal, while in a non-resonant scenario, the device functions as a filter, preserving normal signal propagation and maintaining system security-a process reliant on the space-charge field $ESCE_{\text{SC}}$.

Researchers have developed an integrated optical fuse leveraging the photorefractive effect to automatically protect quantum key distribution systems from malicious signal manipulation.
