yeezyseason3 said:Is it possible to produce an entangled photon pair and be able to delay the reception times by introducing something like a fiber bragg grating which has multiple indices of refraction which propagate wavelengths at different frequencies? Or will, because of their entangled state, do some "spooky things" according to Einstein and as a result won't work?
Asynchronous entangled photon pairs are a type of quantum resource that consists of two photons that are entangled, meaning that their quantum states are correlated with each other. These photons are asynchronous, meaning that they are not emitted at the same time, but rather are separated by a short time delay.
Asynchronous entangled photon pairs are typically generated using a process called spontaneous parametric down-conversion, where a high-energy photon is split into two lower-energy photons. These photons are then entangled with each other.
Asynchronous entangled photon pairs have potential applications in quantum communication and information processing. They can be used to transmit information securely over long distances, as any attempt to intercept the photons and measure their state would disrupt their entanglement and be detectable by the sender and receiver.
Asynchronous entangled photon pairs can be detected using photon detectors, which are able to measure the arrival time and energy of individual photons. The measurements of each photon are then compared, and if they are correlated, it indicates the presence of entanglement.
One of the main challenges in using asynchronous entangled photon pairs is maintaining the entanglement over long distances. As the photons travel through different environments, their quantum states can become disturbed, leading to a loss of entanglement. Additionally, the detection of these photons can be difficult and requires sensitive equipment.
