タイトル	Nonlinear-interferometric generation of number-phase-correlated fermion states
著者	Kitagawa, Masahiro Kitagawa, Masahiro
著者	Ueda, Masahito Ueda, Masahito
抄録	We propose a nonlinear-interferometric scheme for generating two fermion states correlated in particle number or in wave phase. This scheme can be used for surpassing either the standard quantum limit of the number-partition noise or that of the interferometric phase sensitivity, up to a factor of the order of (total particle number)1/3. A possible experimental scheme in a mesoscopic system is discussed.
