Interference-based universal decoupling and swapping

ORAL

Abstract

Hybrid quantum devices and networks require quantum control of bosonic modes associated with different bosonic platforms. Due to couplings with other modes, even elementary operations like beam splitters might not be immediately available. In this work, we present a universal interference-based scheme for converting multi-mode Gaussian interactions into decoupling or swapping operation of arbitrary selected modes. The scheme only requires multiple uses of the same multi-mode Gaussian interaction interleaved with single-mode Gaussian operations, which can be implemented experimentally. Since the theory is derived from fundamental physical laws, it is applicable to various bosonic physical platforms.
