This video discusses a new quantum network entanglement chip developed by Cisco. The speakers explain the chip's function, its potential to revolutionize quantum computing by enabling scalable, distributed systems, and its immediate applications in enhancing cybersecurity and improving the speed and fairness of high-frequency trading.
The video explains that using entangled photons for communication creates a form of "easedrop-proof" security. If an attacker tries to intercept the communication, they will inevitably collapse the entangled quantum state between the sender and receiver. This immediate collapse alerts both parties to the presence of an eavesdropper, preventing the attacker from synchronizing with the end host or client and obtaining the information.
The transcript doesn't detail how an attacker might try to synchronize with the entangled photons; however, it implies that any attempt to measure or interact with the photons would result in the state collapse, thus revealing the attack.
The speaker uses the example of Game of Thrones (and other medieval depictions) to illustrate the concept of decision coordination. He contrasts the relatively slow method of sending a messenger with a banner announcing an approaching enemy, to the instantaneous communication achieved by lighting a series of signal fires on hilltops. This analogy highlights the speed and efficiency improvement offered by quantum entanglement for simultaneous communication across geographically dispersed locations, similar to the instantaneous nature of the signal fires compared to a messenger.
The transcript doesn't describe methods an attacker might use to intercept the entangled photons without causing a state collapse. The core security feature relies on the principle that any interaction with the entangled photons will reveal the eavesdropping attempt. The video focuses on the inherent security of the entanglement, not on potential countermeasures an attacker might employ. Therefore, I cannot answer your question based solely on the provided transcript.
