Multiport quantum interferometry with universal nonunitary transformations

Quantum interferometry provides a pivotal method for investigating complex photon-photon interaction, enabling various quantum information technologies that beyond the possibilities of classical physics. While such an effective interaction is mostly studied in N × N unitary transformation, m × n nonunitary transformati...

Anomalous quantum beats by coherent absorption of frequency-entangled photons

Abstract. Quantum beats, the fact that periodic oscillations arise from coherent superposition of frequency-distinguishable states, have enabled various quantum information technologies beyond the possibilities of classical physics. Although the conventional quantum beats are based on unitary optical elements, we prese...
