Quantum entanglement/teleportation does not mean information transmission exceeds the speed of light. You’re still limited to sending entangled particles to your destination following the laws of physics. You cannot transmit information via this phenomenon.
What you can use this for is transmission integrity. Where you will know if an outside observer intercepted your transmission then sent it on its way to the destination. This is more commonly known as a man in the middle attack (MitM).
Ooo thank you, I’m definitely out of date by now
