A complete quantum metrology theory for N-mode bosonic interferometers, founded on the Sp(2N, R) symmetry, now exists. Chenwei Lv and Renbao Liu at the Chinese University of Hong Kong have established this theory, where 2N defines the size of a key symmetric matrix. The theory describes how multimode quantum interferometers function, devices employing multiple beams…
