8, the electromagnetically induced transparency 15, 16, 17 (EIT)-based double-Λ-type atomic system has been actively implemented for efficiently creating nondegenerate entangled twin fields through either nondegenerate four-wave mixing (FWM) or Raman scattering processes 9, 10, 11, 12. Based on the seminal proposal of Duan et al. Apart from the conventional way of generating multipartite entanglement by mixing squeezed fields created through parametric down-conversion processes in nonlinear optical crystals with linear optical elements, i.e., polarizing beam splitters (PBS) 4, 5, 6, 7 as entanglers, the atomic ensembles provide an alternative avenue to the generation of multi-entangled fields due to the virtue of narrow bandwidth, nondegenerate frequencies and long correlation time 8, 9, 10, 11, 12, 13, 14. So far, the majority studies on entanglement have dealt with the generations of multiple entangled light fields. In facilitating quantum information processing and quantum networks, generations of light-light, atom-atom and atom-light multipartite entanglements play essential roles in the implementations of quantum information protocols 1, 2, 3. As is well known, light is the best long-distance quantum information carrier and the atomic ensembles can provide the promising tools for quantum information manipulation and storage. Quantum state exchange between light and matter is a basic component for quantum interface in quantum information processing. This scheme holds great promise for applications in scalable quantum communication and quantum networks. With such an entangler, any desired number of nondegenerate narrow-band continuous-variable entangled fields, in principle, can be generated through stimulated Raman scattering processes. The atomic spin wave, produced through EIT in the Λ-type atomic system, can be described by a Bose operator and can act as an entangler. Here, we present a proof-of-principle demonstration of an efficient and convenient way to entangle multiple light fields via electromagnetically induced transparency (EIT) in an atomic ensemble. However, nonclassical input light fields are required and the generated entangled fields are always degenerate in such case. One of the commonly-used methods to generate multiple entangled fields is to employ polarizing beam splitters. Unequipping the Quantum Entangler too quickly after the coordinate point is set may deactivate the coordinate point and put Quantum Entangler on cooldown for 30 seconds.Quantum entanglement plays an essential role in quantum information processing and quantum networks.Walking too close to another spawn point or even teleporting across the map to another spawn point before the coordinate point is set up may cause the coordinate point to be set up directly at your location, regardless of where you initially started setting the coordinate point.As Quantum Entangler set up on the closest spawn point, make sure you don't wander too far away from the desired spawn point until it is fully set up.Doing this instead of fully waiting out setting the coordinate point will put the Quantum Entangler on cooldown.When you use the Quantum Entangler, unequipping it right before the teleport is set it will still set the teleport but add a 30 seconds cooldown before use.This can be avoided by quickly canceling the teleport once it's casted.Canceling Quantum Entangler mid-teleport will damage the user shortly after.Coordinate points of the Quantum Entangler can be relocated after the initial coordinate point set has been used or canceled.Quantum Entangler does not save coordinate points through death previous coordinate points set before death will be erased after respawning.Unlike the Gap, the Quantum Entangler can be used while moving.Cannot unequip early if coordinate point has just been set (else risk deactivating and putting Quantum Entangler on cooldown).Requires correct timing to pull off a quick switch.Settable teleport (Closest Spawn Point).This red text, line, and the point itself is invisible to all other players. In addition, a dotted line links the point and player together. To help players with identifying where they are suppose to be teleported, the point is displayed with multiple red texts that accurately shows the number of distance in studs from the player. Upon using the Quantum Entangler a second time, a bright light is emitted as the user teleports to the said point after a short delay. This point remains still and cannot be moved by any means. When first used, the Quantum Entangler will create a coordinate point where the user is currently standing, granted if the player is close to a spawn point.
