Each of these entities employs unique approaches and innovations to further photonic quantum computing.
Some notable systems highlighted include the Jiuzhang series of quantum computers from USTC, which have demonstrated quantum computational advantage, particularly through their implementation of Gaussian boson sampling (GBS). Jiuzhang’s processors, notably versions 2.0 and 3.0, have successfully executed large-scale GBS tasks, underscoring significant advances in photonic technology and paving the way for groundbreaking applications and a deeper understanding of quantum computational power.
ORCA Computing's modular and fiber-interconnected systems leverage existing telecommunication infrastructure to provide robust and scalable solutions. Their approach intricately combines modular design with state-of-the-art quantum memory, enhancing the practical deployment of quantum computing systems.
The efforts of PsiQuantum are particularly noteworthy, as they focus on using photons to realize fault-tolerant computation through fusion-based quantum computing (FBQC). Their approach articulates a path towards significantly higher fault tolerance thresholds using fusion networks, prominently impacting applications ranging from cryptography to industrial molecular simulations.
Quandela's development of the scalable MosaiQ platform and the two-qubit Ascella quantum processor highlights the nascent steps towards user-accessible quantum computing systems, capable of executing complicated calculations with high precision and fidelity.
The Xanadu Borealis system marks another highlight, achieving quantum computational advantage through a fully programmable photonic quantum processor using high-dimensional GBS within a dynamic programmable architecture, demonstrating results that outperform classical supercomputers by several orders of magnitude.
The multitude of quantum photonic developments detailed in the paper indicate significant promise and potential for practical applications in fields such as secure communications, optimization, and complex simulations critical to industries like pharmaceuticals and material sciences.
