Abstract: We propose and investigate an optical scheme for probabilistic implementationof an arbitrary single-mode quantum operation that can be expressed as afunction of photon number operator. The scheme coherently combines multiplephoton addition and subtraction and is feasible with current technology. Asconcrete examples, we demonstrate that the device can perform approximatenoiseless linear amplification of light and can emulate Kerr nonlinearity.
