Physicists propose the first scheme to teleport the memory of an organism
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.
In a recent study, Tongcang Li and Zhang-qi Yin propose to put a bacterium on top of an electromechanical membrane oscillator integrated with a superconducting circuit to prepare the quantum superposition state of a microorganism and teleport its quantum state. A microorganism with a mass much smaller than the mass of the electromechanical membrane will not significantly affect the quality factor of the membrane and can be cooled to the quantum ground state together with the membrane. Quantum superposition and teleportation of its center-of-mass motion state can be realized with the help of superconducting microwave circuits. With a strong magnetic field gradient, the internal states of a microorganism, such as the electron spin of a glycine radical, can be entangled with its center-of-mass motion and be teleported to a remote microorganism. Since internal states of an organism contain information, this proposal provides a scheme for teleporting information or memories between two remote organisms.
