Integrated high-dimensional time-bin entanglement analyzers for scalable quantum photonics

Nicola Montaut, Stefania Sciara, Mario Chemnitz +9 more

High-dimensional time-bin analyzers are essential for characterizing quantum states in photonic systems. We present advancements in fiber- and chip-based platforms for generating and analyzing time-bin entanglement, emphasizing ultrastable fiber architectures, scalable quantum key distribution, and post-selection-free measurements, enabling robust and scalable quantum communication and processing.

On-chip quantum teleportation

B. J. Metcalf, Nicholas L. Thomas-Peter, Justin B. Spring +10 more

Integrated quantum optics provides great promise for enabling photonic experiments to reach new regimes of complexity. Chip-based fabrication enables sophisticated networks involving multiple interfering pathways in a compact and stable physical architecture. In a recent work we demonstrated an advance in the complexity of these integrated devices by showing the first quantum interference of three separate input photons. Such complexity allows the demonstration of three qubit protocols never before realised on-chip. Here, we report the first results showing quantum teleportation on an integrated photonic circuit. Quantum teleportation provides the mechanism for quantum relay schemes and is an important constituent in linear optical quantum computing. Whilst demonstrations to date have relied upon complex and fragile bulk optical systems, being able to teleport quantum states on a compact and stable integrated architecture will be a critical step towards scalable realisations of these schemes.

Blueprint for a scalable photonic fault-tolerant quantum computer

J. Eli Bourassa, Rafael N. Alexander, Ben Q. Baragiola +1 more

Photonics is the platform of choice to build a modular, easy-to-network quantum computer operating at room temperature. However, no concrete architecture has been presented so far that exploits both the advantages of qubits encoded into states of light and the modern tools for their generation. Here we propose such a design for a scalable fault-tolerant photonic quantum computer informed by the latest developments in theory and technology. Central to our architecture is the generation and manipulation of three-dimensional resource states comprising both bosonic qubits and squeezed vacuum states. The proposal exploits state-of-the-art procedures for the non-deterministic generation of bosonic qubits combined with the strengths of continuous-variable quantum computation, namely the implementation of Clifford gates using easy-to-generate squeezed states. Moreover, the architecture is based on two-dimensional integrated photonic chips used to produce a qubit cluster state in one temporal and two spatial dimensions. By reducing the experimental challenges as compared to existing architectures and by enabling room-temperature quantum computation, our design opens the door to scalable fabrication and operation, which may allow photonics to leap-frog other platforms on the path to a quantum computer with millions of qubits.
