In the first half of the twentieth century, revolution broke out in the classical mechanics, which was the first time after Newton's one. Quantum mechanics became reality. It changed a view of the world. Art and science adapted to the method that referred to quantum mechanics. Quantum computation, which was published by David Deutsch in 1985, was one of the examples. In the art world, Yutaka Matsuzawa made a work named "Quantum Art Manifesto" in 1988. Matsuzawa said that, "This is art whose concept is approximated to the quantum mechanics." By the way, his atelier is called "psi." "Psi" means the wave function in quantum mechanics and, in the meantime, this side of the end. "Psi" is an important term for Matsuzawa's thoughts in art. Poems are the mirror of the world view of the same age. Quantum Poem should be a concept. It was delayed for twenty years though. Keisuke Mitsuhashi is a music critic. He and I had published an email magazine called "Every five days to be announced on the performance day" since March 11 until June 14, 2002. We sent 20 email magazines for a hundred days. The following is the text I continued to write in that magazine. "March 6, 2002, Tokyo. Today's Weather Forecast from THE MAINICHI NEWSPAPERS. Highs and lows. 8 degrees centigrade and 20 today. 7 and 13 tomorrow. 4 and 13 the day after tomorrow. 6 and 16 two days after tomorrow. I wrote 2 lines for "Pure Poem" today. I renewed my Website. March 7, 2002, Tokyo. Today's Weather Forecast from THE MAINICHI NEWSPAPERS. Highs and lows. 5 degrees centigrade and 15 today. 4 and 12 tomorrow. 6 and 17 the day after tomorrow. 9 and 17 two days after tomorrow. I wrote 1 line for "Pure Poem" today. (Same as above)" This text is based on "Quantum Poem." This poem presents "Many- Worlds Interpretation of Quantum Mechanics" by presenting documented weather forecast. Also ancient poems were prophecy, and they were concerned with the future. I attempt to remake the ancient poems by using the modern method. I don't wish a dramatic event. I need to present a phenomenon itself. Who needs the figuration of arranged past? I would like to document all phenomena, but we do not have to understand phenomena. I call my works "Quantum Poem" which should have been written in the twentieth century.
