Tunable quantum interference using a topological source of indistinguishable photon pairs
Sunil Mittal, Venkata Vikram Orre, Elizabeth A. Goldschmidt +1
Sources of quantum light, in particular correlated photon pairs that are indistinguishable in all degrees of freedom, are the fundamental resource that enables continuous-variable…
Interference of Temporally Distinguishable Photons Using Frequency-Resolved Detection
Venkata Vikram Orre, Elizabeth A. Goldschmidt, Abhinav Deshpande +4
We demonstrate quantum interference of three photons that are distinguishable in time, by resolving them in the conjugate parameter, frequency. We show that the multiphoton interfe…
Photonic Anomalous Quantum Hall Effect
Sunil Mittal, Venkata Vikram Orre, Daniel Leykam +2
We experimentally realize a photonic analogue of the anomalous quantum Hall insulator using a two-dimensional (2D) array of coupled ring resonators. Similar to the Haldane model, o…
Photonic quadrupole topological phases
Sunil Mittal, Venkata Vikram Orre, Guanyu Zhu +3
The topological phases of matter are characterized using the Berry phase, a geometrical phase, associated with the energy-momentum band structure. The quantization of the Berry pha…
Temporal and spectral manipulations of correlated photons using a time-lens
Sunil Mittal, Venkata Vikram Orre, Alessandro Restelli +3
A common challenge in quantum information processing with photons is the limited ability to manipulate and measure correlated states. An example is the inability to measure picosec…
Topologically robust transport of entangled photons in a 2D photonic system
Sunil Mittal, Venkata Vikram Orre, Mohammad Hafezi
We theoretically study the transport of time-bin entangled photon pairs in a two-dimensional topological photonic system of coupled ring resonators. This system implements the inte…
