Schr ? 在活着、死了的状态的重叠准备一只猫的 dingers 思维实验揭示量力学的深刻后果并且吸引了庞大的兴趣。这里,我们建议一个直接方法由把一个小 cryopreserved 细菌放在一个机电的振荡器上创造生活微生物的量重叠状态。我们的建议基于 15-m-diameter 铝膜的 center-of-mass 摆动被凉下来到它的量地面状态的最近的开发(Teufel 等。在自然 475:359, 2011 ) ,并且与一块微波地纠缠了(Palomaki 等。在科学 342:710, 2013 ) 。有比机电的膜的团小得多的一个团的微生物显著地不影响膜的优秀因素并且能和膜被凉下来到量地面状态。它的 center-of-mass 运动状态的量重叠和远距传物能在超导的微波电路的帮助下被认识到。更重要地,微生物的内部状态例如一个 glycine 激进分子的电子旋转,能与它的 center-of-mass 运动和 teleported 被纠缠到遥远的微生物。我们的建议能与最先进的技术被认识到。建议安装是量有限磁性的回声力量显微镜。因为一个有机体的内部状态包含信息,我们的建议也为在二个遥远的有机体之间的 teleporting 信息或记忆提供一个计划。

英文摘要:

Schrodinger's thought experiment to prepare a cat in a superposition of both alive and dead states reveals profound consequences of quantum mechanics and has attracted enormous interests. Here we propose a straight- forward method to create quantum superposition states of a living microorganism by putting a small cryopreserved bacterium on top of an electromechanical oscillator. Our proposal is based on recent developments that the center- of-mass oscillation of a 15-pro-diameter aluminum mem- brane has been cooled to its quantum ground state (Teufel et al. in Nature 475:359, 2011), and entangled with a microwave field (Palomaki et al. in Science 342:710, 2013). A microorganism with a mass much smaller than the mass of the electromechanical membrane will not signifi- cantly affect the quality factor of the membrane and can be cooled to the quantum ground state together with themembrane. Quantum superposition and teleportation of its center-of-mass motion state can be realized with the help of superconducting microwave circuits. More importantly, 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 teleported to a remote microorganism. Our proposal can be realized with state-of-the-art tech- nologies. The proposed setup is a quantum-limited mag- netic resonance force microscope. Since internal states of an organism contain information, our proposal also pro- vides a scheme for teleporting information or memories between two remote organisms.
