In "Star Trek," a transporter can teleport a person from one location to a remote location without actually making the journey along the way. Such a transporter has fascinated many people. Quantum teleportation shares several features of the transporter and is one of the most important protocols in quantum information. In a recent study, Prof. Tongcang Li at Purdue University and Dr. Zhang-qi Yin at Tsinghua University proposed the first scheme to use electromechanical oscillators and superconducting circuits to teleport the internal quantum state (memory) and center-of-mass motion state of a microorganism. They also proposed a scheme to create a Schrödinger's cat state in which a microorganism can be in two places at the same time. This is an important step toward potentially teleporting an organism in future.
Quantum teleportation between two microorganisms is shown. The internal state (an electron spin) or the center-of-mass motion state of a microorganism on an electromechanical oscillator can be teleported to a remote microorganism on another electromechanical oscillator assisted with superconducting circuits.
