We propose a passive all optical device capable of transforming the orbital angular momentum (OAM) state of light conditioned over the polarization states. The efficiency of this device is ensured due to its linear optical nature. As applications of this device, we show CNOT and SWAP operations between polarization and OAM qubits, non-interferometric OAM mode sorter and generalized Pauli X operation on a four-dimensional subspace of OAM.
我们提出了一种无源全光器件，它能够根据偏振态变换光的轨道角动量（OAM）状态。由于其线性光学性质，该器件的效率得到了保证。作为该器件的应用，我们展示了偏振和OAM量子比特之间的CNOT和SWAP操作、非干涉式OAM模式分选器以及在OAM的四维子空间上的广义泡利X操作。
