Abstract

We demonstrate for the first time a proof of concept of a frequency-domain fully-connected network using parallel frequency-domain measurements applied to frequency-entangled photon pairs from 21 GHz Silicon On Insulator (SOI) micro-resonator.

Generation and Parallel Manipulation of Frequency Entangled Qubits from a 21 GHz Silicon-On-Insulator Micro-Resonator

Antoine Henry, Dario Fioretto, Lorenzo Proccopio +8 more

The Silicon On Insulator (SOI) is a promising platform for the generation of correlated and entangled photon pairs, as silicon photonics inherits the precise, mature, and accurate technologies from Silicon micro-electronics and allows the large-scale production of integrated photonic chips. In particular, high-quality-factor micro-resonators are well suited for producing telecom-wavelength bi-photon frequency combs, key elements for quantum information, as telecom photons are good candidates for the future links between quantum communication nodes or quantum computers [1]. Using the frequency domain for encoding information is an elegant way to access a high-dimensional Hilbert space, in one spatial mode. Recent progress in the manipulation using electro-optics devices leveraged versatile applications [2] and Hadamard gates have been implemented with classical light [3]

Parallelization of frequency domain quantum gates: manipulation and distribution of frequency-entangled photon pairs generated by a 21 GHz silicon microresonator

Antoine Henry, Dario Fioretto, Lorenzo M. Procopio +8 more

Harnessing the frequency dimension in integrated photonics offers key advantages in terms of scalability, noise resilience, parallelization, and compatibility with telecom multiplexing techniques. Integrated ring resonators have been used to generate frequency-entangled states through spontaneous four-wave mixing. However, state-of-the-art integrated resonators are limited by trade-offs among size, spectral separation, and efficient photon pair generation. We have developed silicon ring resonators with a footprint below 0.05 mm2 providing more than 70 frequency channels separated by 21 GHz. We exploit the narrow frequency separation to parallelize and independently control 34 single qubit-gates with a single set of three off-the-shelf electro-optic devices. We fully characterize 17 frequency-bin maximally entangled qubit pairs by performing quantum state tomography. We demonstrate for the first time, we believe, a fully connected five-user quantum network in the frequency domain. These results are a step towards a generation of quantum circuits implemented with scalable silicon photonics technology, for applications in quantum computing and secure communications.

Frequency-bin entangled comb of photon pairs from a Silicon-on-Insulator micro-resonator

Jun Chen, Zachary H. Levine, Jingyun Fan +1 more

We present a quantum-mechanical theory to describe narrowband photon-pair generation via four-wave mixing in a Silicon-on-Insulator (SOI) micro-resonator. We also provide design principles for efficient photon-pair generation in an SOI micro-resonator through extensive numerical simulations. Microring cavities are shown to have a much wider dispersion-compensated frequency range than straight cavities. A microring with an inner radius of 8 μm can output an entangled photon comb of 21 pairwise-correlated peaks (42 comb lines) spanning from 1.3 μm to 1.8 μm. Such on-chip quantum photonic devices offer a path toward future integrated quantum photonics and quantum integrated circuits.
