Quantum Teleportation Becomes Possible

Researcher have succeeded in transferring information via Quantum Teleportation .

According to a Phys.org report, quantum teleportation is one of the most important protocols in quantum information. 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 in a recent study.

These researchers 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.

Erwin Schrödinger proposed a famous thought experiment to place a cat in a superposition of both being alive and dead states in 1935; this has been the conceptual basis for many Physicists to make great efforts over many decades to investigate macroscopic quantum phenomena.

Recently, quantum ground state cooling and the creation of superposition states of mechanical oscillators have been realized. For example, a group in Colorado, U.S. has cooled the vibration of a 15-micrometer-diameter aluminum membrane to quantum ground state, and entangled its motion with microwave photons. However, the quantum superposition of an entire organism was not realized.

In 2015, a group at University of Science and Technology of China demonstrated the quantum teleportation of multiple degrees of freedom of a single photon. However, existing experiments are still far away from teleporting an organism or the state of an organism.

"We propose a straightforward method to put a microorganism in two places at the same time, and provide a scheme to teleport the quantum state of a microorganism. I hope our unconventional work will inspire more people to think seriously about quantum teleportation of a microorganism and its potential applications in the future," Li says.
