Abstract（参考訳）: 量子フィッシャー情報(quantum fisher information, qfi)は、量子情報理論において重要な役割を果たす。 しかし、QFIの計算は一般に計算に要求されるタスクである。 WebAs an indicator of estimation precision, quantum Fisher information (QFI) lies at the heart of quantum metrology theory. In this work, an effective scheme for enhancing QFI is proposed by utilizing quantum uncollapsing measurements.
