Observing optical coherence across Fock layers with weak-field homodyne detectors

While most quantum optical techniques reveal either the wave or particle nature of light, weak-field homodyne detection combines wave- and particle-like descriptions. Here, Donati et al.employ this hybrid detection scheme to study the coherence between photon number states across two-mode entangled states.

Self-calibrating programmable photonic integrated circuits

Researchers demonstrate a self-calibrating programmable photonic integrated circuit. The findings may be useful for the accurate control of large-scale photonic integrated circuits in applications such as light-based machine learning.

Direct observation of the particle exchange phase of photons

An interferometric technique is developed to measure the particle exchange phase of indistinguishable photons. The exchange phase obtained is (−0.04 ± 0.07) radians, which clearly demonstrates the symmetric nature of the two-photon wave functions.

Tracking attosecond electronic coherences using phase-manipulated extreme ultraviolet pulses

Light pulses with controllable parameters are desired for studying the fundamental properties of matter. Here the authors generate and use phase-manipulated and highly time-stable XUV pulse pairs to probe the coherent evolution and dephasing of XUV electronic coherences in helium and argon.
