Накратко на български

Квантовите точки в наноструктури се изследват, за да се създадат нелинейни взаимодействия между светлината и материята. Това помага за изграждането на по-мащабируеми фотонни квантови симулатори, компютри и комуникационни мрежи.

Quantum Simulation with Universal Nonlinear optics

Devices that exploit the laws of quantum physics provide fundamentally new opportunities and computational advantages with respect to conventional or classical hardware. By exploiting an inherently new way to encode and process information, quantum technologies promise multiple disruptive applications: enormous computational speed-ups via quantum computers and simulators, unconditionally secure communication networks, and quantum-enhanced sensors. Amongst the leading quantum platforms, photons offer unique advantages as quantum information carriers: low noise, long-distance transmission, high-speed, and high manufacturability of quantum photonic circuits. Recent advances for near-term industrially relevant applications for photonic simulators, as well as resource-efficient fault-tolerant linear-optical quantum computing architectures, have opened exciting new prospects for photonic quantum technologies, spurring large investments in quantum photonic companies (e.g., PsiQuantum, Xanadu, Photonic Inc.). However, an important hurdle currently limits the scaling up of quantum photonic devices: the lack of near-deterministic nonlinearities in quantum photonic circuits for quantum simulators and scalable generation of multi-photon entanglement. The aim of this project is to develop a technology to address this central limitation, nonlinear quantum photonics, enabling transformative quantum technologies for photonic quantum simulation, computing, and networking. In particular, the proposed project aims at addressing scientific gaps by introducing nonlinear quantum operations through light-matter interactions in quantum dots embedded in photonic nanostructures. These devices are then integrated in programmable linear-optical circuitry to build a scalable platform for developing multi-mode nonlinear quantum photonic. The action involves technology developments targeting applications in near-term devices, focusing on molecular quantum dynamics simulation, as well as progress towards hardware for longer-term general-purpose quantum computers. The goals represent significant scientific breakthroughs, outlined in the following key objectives: (O1) Demonstration of universal nonlinear photonic circuits interconnecting nonlinear operations and programmable linear optics. (O2) Implementation of anharmonic molecular dynamics quantum simulation in a programmable nonlinear interferometer.

Цел на проекта

Quantum information processing is a transformative technology that will address societal needs by obtaining unprecedented computational power with quantum computers and simulators, unconditionally secure quantum communications, and quantum-enhanced sensors. Photons play a central role in the development of quantum technologies due to their unique capability to encode quantum information with low-noise, transmit it over long distances, and process it in scalable photonic circuits. However, the lack of photon-photon nonlinearities poses a central challenge in the development of photonic quantum technologies. The aim of this proposal is to address this limitation for next-generation quantum photonic devices. The enabling technology is the combination of two quantum photonic platforms: light-matter interactions with quantum dot emitters in integrated nanostructures, and programmable quantum photonic circuits performing universal transformation in the temporal degree of freedom. Through the use of high-quality light-matter interfaces and efficient interconnection with photonic circuitry, this project will (1) develop devices able to perform high-quality programmable nonlinear circuits, and (2) demonstrate how such devices can be used to implement near-term applications, focusing on the quantum simulation of anharmonic molecular dynamics. The developed platform solves a critical set of challenges that have limited the scaling of quantum photonic devices, enabling transformative quantum photonic technologies for quantum computing and networking. The synergy between my strong experience in programmable quantum photonic devices and applications, the world-leading expertise of Prof. Lodahl’s host group in integrated light-matter interactions, and the high interdisciplinarity of the Niels Bohr Institute and University of Copenhagen, makes us uniquely placed to execute this ambitious project.
