Reprogrammable multi-channel interferometers are the tool for new approaches to information processing, both classical and quantum. Until recently, reprogrammable interferometers were created using architectures (i.e., methods of elementary blocks combining) which are sensitive to errors that occur at the manufacture stage. The proposed technology solves this problem by using two new interferometer architectures that differ in the elementary blocks and the way they are connected to each other in a multichannel scheme. There is no need to use additional elements to be able to correct errors in contrast to previously known schemes.
