Entanglement of up to 6 photons on a silicon photonic quantum circuit

Jong-Moo Lee, Woncheol Shin, Tae‐Wan Kim, Yongsoo Hwang

Abstract

Six-photon entanglement is demonstrated on a silicon photonic circuit integrating spirals, spectral filters, and linear-optic gates for eight path-encoded qubits. The indistinguishability of photons is verified through a 97% Hong-Ou-Mandel visibility measurement.

We demonstrate 98% Hong-Ou-Mandel (HOM) visibility, 82% Green-berger–Horne–Zeilinger (GHZ) fidelity, and Bell’s inequality violations by 4-photon coincident measurements using a silicon-photonic chip including photon-pair sources, filters, and linear-optic gates.

Advances in Silicon Quantum Photonics

Jeremy C. Adcock, Jueming Bao, Yulin Chi +6 more

Quantum technology is poised to enable a step change in human capability for computing, communications and sensing. Photons are indispensable as carriers of quantum information-they travel at the fastest possible speed and readily protected from decoherence. However, the system requires thousands of near-transparent components with ultra-low-latency control. To be implemented, a new paradigm photonic system is required: one with in-built coherence, stability, the ability to define arbitrary circuits, and a path to manufacturability. Silicon photonics has unparalleled density and component performance, which, with CMOS compatible fabrication, place it in a strong position for a scalable quantum photonics platform. This paper is a progress report on silicon quantum photonics, focused on developments in the past five years. We provide an introduction on silicon quantum photonic component and the challenges in the field, summarise the current state-of-the-art and identify outstanding technical challenges, as well as promising avenues of future research. We also resolve a conflict in the definition of Hong-Ou-Mandel interference visibility in integrated quantum photonic experiments, needed for fair comparison of photon quality across different platforms. Our aim is the development of scalability on the platform, to which end we point the way to ever-closer integration, toward silicon quantum photonic systems-on-a-chip.

Silicon Integrated Quantum Photonics

Ding Y, Bacco D., Rottwitt K. +3 more

Quantum photonics opens a new era of technology revolution deeply embedded in quantum mechanism. Silicon integrated quantum photonics is of particular interest able to integrate mass of quantum photonic components on a single silicon chip. Here we present our recent work on silicon photonics for advanced quantum applications, including high-dimensional quantum quantum key distribution, high-dimensional quantum entanglement, and Hong-Ou-Mandel interference of two independent lasers on silicon for quantum communication.

Silicon Photonics for Quantum Communication

Yunhong Ding, Davide Bacco, D. Llewellyn +8 more

Silicon quantum photonics, capable to integrate large numbers of optical components with CMOS-compatible fabrication technology and reliable control of quantum states, is expected to play a critical role in future quantum communication. In this talk, we will introduce our recent results of silicon photonics for quantum communication, including high-dimensional silicon chip-to-chip quantum key distribution, chip-to-chip quantum teleportation, on-chip generation of high-dimensional quantum entanglement, and Hong-Ou-Mandel interference between two different III-V/silicon hybrid lasers towards future measurement device independent quantum communication.

Do different kinds of photon-pair sources have the same indistinguishability in quantum silicon photonics?

Jong-Moo Lee, Alessio Baldazzi, Matteo Sanna +5 more

In the same silicon photonic integrated circuit, we compare two types of integrated degenerate photon-pair sources (microring resonators and waveguides) using Hong–Ou–Mandel (HOM) interference experiments. Two nominally identical microring resonators are coupled to two nominally identical waveguides, which form the arms of a Mach–Zehnder interferometer. This is pumped by two lasers at two different wavelengths to generate, by spontaneous four-wave mixing, degenerate photon pairs. In particular, the microring resonators can be thermally tuned in or out of resonance with the pump wavelengths, thus choosing either the microring resonators or the waveguides as photon-pair sources, respectively. In this way, an on-chip HOM visibility of 94% with microring resonators and 99% with straight waveguides is measured upon filtering. We compare our experimental results with theoretical simulations of the joint spectral intensity and the purity of the degenerate photon pairs. We verify that the visibility is connected to the sources’ indistinguishability, which can be quantified by the overlap between the joint spectral amplitudes (JSA) of the photon pairs generated by the two sources. We estimate a JSA overlap of 98% with waveguides and 89% with microring resonators.
