Protecting the Quantum Interference of Cat States by Phase-Space Compression
Original language description
Cat states, with their unique phase-space interference properties, are ideal candidates for understanding fundamental principles of quantum mechanics and performing key quantum information processing tasks. However, they are highly susceptible to photon loss, which inevitably diminishes their quantum non-Gaussian features. Here, we protect these non-Gaussian features against photon loss by compressing the phase-space distribution of a cat state.We achieve this compression with a deterministic technique based on the echoed conditional displacement operation in a circuit QED device.We present a versatile technique for creating robust non-Gaussian continuous-variable resource states in a highly linear bosonic mode and manipulating their phase-space distribution to achieve enhanced resilience against photon loss. Suchcompressed cat states offer an attractive avenue for obtaining new insights into quantum foundations and quantum metrology, as well as for developing inherently more protected bosonic code words for quantum error correction.
