Notable Quotes
This is incredibly exciting because nobody thought it was possible. Our work shows a path towards next-generation quantum and classical networks sharing a unified fiber optic infrastructure. It opens the door to pushing quantum communications to the next level.
By performing a destructive measurement on two photons—one carrying a quantum state and one entangled with another photon—the quantum state is transferred onto the remaining photon, which can be very far away. Teleportation allows the exchange of information over great distances without requiring the information itself to travel that distance.
Quantum teleportation has the ability to provide quantum connectivity securely between geographically distant nodes... But many people have long assumed that nobody would build specialized infrastructure to send particles of light. If we choose the wavelengths properly, we won’t have to build new infrastructure. Classical communications and quantum communications can coexist.
Conclusion
Recent experiments demonstrating quantum teleportation and quantum key distribution over existing fiber networks mark a pivotal step toward a quantum internet. These breakthroughs show that quantum data can coexist with classical traffic, reducing infrastructure costs and accelerating the development of quantum technologies. While challenges remain, these advancements pave the way for secure communication, ultra-fast computing, and advanced sensing, potentially transforming various industries.
