Abstract

The temporal distinguishability in an unbalanced interferometer leads to the erasure of interference in the direct photodetection which can be recovered via amplitude measurement by homodyne detection.

We report a method of homodyne detection that can recover otherwise lost interference effect in an unbalanced SU(1,1) interferometer. The indistinguishability due to amplitude measurement and slow detection is responsible for the recovery of interference.

Measurement-dependent erasure of distinguishability for the observation of interference in an unbalanced SU(1,1) interferometer

Nan Huo, Liang Cui, Yunxiao Zhang +4 more

It is known that quantum interference can disappear with the mere possibility of distinguishability without actually performing the act. We create such distinguishability in an unbalanced SU(1,1) interferometer and indeed observe no interference in the direct photodetection of the outputs. On the other hand, such distinguishability can be erased with a projective measurement. Here, we report a method of homodyne detection that can also recover interference effect. We find that it is the indistinguishability in amplitude measurement that leads to the recovery of interference, and the quantum nature of homodyne detection and the detector's slow response time both play an essential role. This is different from the quantum eraser schemes mentioned above. It demonstrates that quantum interference occurs in the measurement processes. With no need for path compensation, the unbalanced interferometers studied here should have practical applications in quantum metrology and sensing.

Quantum interference of single photons with distinguishable paths

Yunxiao Zhang, Liang Cui, Xueshi Guo +4 more

We report a single-photon interference experiment where the interfering paths are in orthogonal polarization and temporal modes. This is achieved through amplitude measurement by homodyne detection so that interference occurs in photo-current after measurement.
