Interferometric Readout of Momentum-Space Topology in a Programmable Dissipative Photonic Circuit
Andrea Cataldo, Emil J. Bergholtz, Daniel Leykam +2
Topology under non-Hermitian dynamics is encoded in the phase of the bulk evolution, yet strong dissipation suppresses the amplitudes carrying it. We resolve this using a programma…
Programmable Non-Hermitian Synchronization of Light on a Silicon Photonic Processor
Ze-Sheng Xu, Nan Cheng, Mohammed S. Elmusrati +6
Synchronization is a pervasive collective phenomenon underlying the firing of neurons, the beating of the heart, and the coherent emission of lasers. Across these systems, dissipat…
Chromatic thresholds for pairs of graphs
Jun Gao, Hong Liu, Zhuo Wu +1
The chromatic threshold of a graph is the minimum-degree density above which every -free graph has bounded chromatic number. We study a two-color Ramsey analogue: for graphs…
Bloch Siegert Physics in a Reconfigurable Photonic Binary Lattice
Ze-Sheng Xu, Liwei Duan, Rohan Yadgirkar +4
The Bloch Siegert shift, a hallmark correction arising from counter-rotating interactions in driven two-level systems, has an exact counterpart in binary lattices under static forc…
Experimental simulation of non-equilibrium quantum piston on a programmable photonic quantum computer
Govind Krishna, Rohan Yadgirkar, Balakrishnan Krishnakumar +6
Quantum fluctuation relations provide a microscopic formulation of thermodynamics beyond equilibrium, but experimentally accessing many-body quantum work statistics remains an outs…
Non-Hermitian Exceptional Topology on a Klein Bottle Photonic Circuit
Ze-Sheng Xu, J. Lukas K. König, Andrea Cataldo +8
Non-Hermitian physics has unlocked a wealth of unconventional wave phenomena beyond the reach of Hermitian systems, with exceptional points (EPs) driving enhanced sensitivity, nonr…
Emulation of Coherent Absorption of Quantum Light in a Programmable Linear Photonic Circuit
Govind Krishna, Jun Gao, Sam O Brien +5
Non-Hermitian quantum systems, governed by nonunitary evolution, offer powerful tools for manipulating quantum states through engineered loss. A prime example is coherent absorptio…
Floquet-driven light transport in programmable photonic processors via discretized evolution of synthetic magnetic fields
Andrea Cataldo, Rohan Yadgirkar, Ze-Sheng Xu +5
Photons, unlike electrons, do not couple directly to magnetic fields, yet synthetic gauge fields can impart magnetic-like responses and enable directional transport. Discretized Fl…
Heterogeneous integration of silicon nitride and amorphous silicon carbide photonics
Zizheng Li, Bruno Lopez-Rodriguez, Naresh Sharma +10
Amorphous silicon carbide (a-SiC) has emerged as a compelling candidate for applications in integrated photonics, known for its high refractive index, high optical quality, high th…
From Pixels to Camera: Scaling Superconducting Nanowire Single-Photon Detectors for Imaging at the Quantum-Limit
Jun Gao, Jin Chang, Bruno Lopez Rodriguez +3
Superconducting nanowire single-photon detectors (SNSPDs) have emerged as essential devices that push the boundaries of photon detection with unprecedented sensitivity, ultrahigh t…
Fourier State Tomography of Polarization-Encoded Qubits
Mohammed K. Alqedra, Pierre Brosseau, Ali W. Elshaari +4
Quantum state tomography is a central technique for the characterization and verification of quantum systems. Standard tomography is widely used for low-dimensional systems, but fo…
On demand single photon generation and coherent control of excitons from resonantly driven nanowire quantum dots
Jun Gao, Govind Krishna, Edith Yeung +10
Coherent control of single photon sources is a key requirement for the advancement of photonic quantum technologies. Among them, nanowire-based quantum dot sources are popular due…
Acoustic modulation of individual nanowire quantum dots integrated into a hybrid thin-film lithium niobate photonic platform
Thomas Descamps, Tanguy Schetelat, Jun Gao +4
Surface acoustic waves (SAWs) are a powerful tool for controlling a wide range of quantum systems, particularly quantum dots (QDs) via their oscillating strain fields. The resultin…
