One of the\nsources of quantum noise is the quantum back-action, which arises from the\nvacuum fluctuation of the light. It sways the mirror via the momentum\ntransferred to the mirror upon its reflection for the measurement. The author\ndiscusses a fundamental trade-off between sensitivity and stability in the\nmacroscopic system, and suggests using a triangular cavity that can avoid this\ntrade-off. The development of an optical triangular cavity is described and its\ncharacterization of the optomechanical effect in the triangular cavity is\ndemonstrated. As a result, for the first time in the world the quantum back-action\nimposed on the 5-mg suspended mirror is significantly evaluated. This work\ncontributes to overcoming the standard quantum limit in the future.\u003c\/p\u003e\n            \u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9784431567202\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9784431558804\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9784431567202","offer_id":39445383610461,"sku":"9784431567202","price":106.99,"currency_code":"EUR","in_stock":true},{"title":"Hardcover - 9784431558804","offer_id":47040294551877,"sku":"9784431558804","price":106.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/14145052-77c1-4444-8397-1dab1cf149b2.jpg?v=1775192463","url":"https:\/\/shop.autorenwelt.de\/en\/products\/classical-pendulum-feels-quantum-back-action-von-nobuyuki-matsumoto","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
