Guiding and confining of light in a two-dimensional synthetic space using electric fields
Hamidreza Chalabi, Sabyasachi Barik, Sunil Mittal +3
Synthetic dimensions provide a promising platform for photonic quantum simulations. Manipulating the flow of photons in these dimensions requires an electric field. However, photon…
Chiral quantum optics using a topological resonator
Sabyasachi Barik, Aziz Karasahin, Sunil Mittal +2
Topological photonic structures exhibit chiral edge states that are robust to disorder and sharp bends. When coupled to quantum emitters, these edge states generate directional lig…
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…
A synthetic gauge field for two-dimensional time-multiplexed quantum random walks
Hamidreza Chalabi, Sabyasachi Barik, Sunil Mittal +3
Temporal multiplexing provides an efficient and scalable approach to realize a quantum random walk with photons that can exhibit topological properties. But two dimensional time-mu…
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…
