Teleportation at the quantum level was demonstrated in several laboratories in the late 20th century.The creation of the quantum computer opened a whole new field of research.It had long been known that when a patient undergoes an MRI examination that it changes the quantum state of atoms in the patient's body. The study of this phenomenon resulted in the creation of teleportation machines.Here are stories from the early days of teleportation. The problems that had to be overcome , the safeguards that had to be introduced to give us the safe system we have today.
