Накратко на български

Фотонни квантови мрежи, базирани на ултрабързи честотни гребени, се разработват за по-бърза обработка на информация чрез контрол на единични фотони. Тези мрежи помагат за създаването на ресурси, необходими за функционирането на квантовите компютри.

Photonic Quantum Network with an Ultrafast Frequency Comb

The primary objective of this action is to develop a photonic quantum network for scalable quantum information processing. By exploiting the intrinsic multimode structure of an ultrafast frequency comb, a quantum network supporting multiple quantum systems is generated, and quantum correlations in the network are optimized to readily conduct a given quantum information task. To benefit from genuine speedup of quantum information processing, elaborate single-photon control is implemented, which affects only specific modes of interest out of multiple frequency modes in the quantum network. The resultant light field becomes a PhotonIc QUAtum NeTwork with an ultrafast frequency comb (PIQUANT), which is an essential quantum resource for quantum information processing. Details activities in this project are: • Optimal preparation of a Gaussian quantum network with an ultrafast frequency comb • Generation of photonic quantum network by employing single-photon control • Full characterization of a photonic quantum network • Measurement based quantum computing using a photonic quantum network As a result of this project, we have generated a versatile photonic quantum network by engineering ultrafast frequency comb in various manners. In the initial step to generate a Gaussian quantum network, shaping the pump frequency comb enables us to modify the structure of the generated quantum network. In addition, we have implemented a single-photon subtractor by engineering ultrafast frequency comb, which converts the Gaussian quantum network into a photonic quantum network that exhibits non-Gaussian statistics. Such non-Gaussian statistics is important for quantum information processing, and is identified as a main resource in quantum computing. The photonic quantum network will have broad applications in quantum information science, e.g., quantum computing, quantum communication, and quantum enhanced measurement.

Цел на проекта

Over the last decades, application of photonic technologies to quantum information science has been very successful, which establishes light as a promising quantum system to carry quantum information. The next stage for advancing photonic technology along with quantum information science is to scale-up the capacity of a quantum system to encode quantum information. In this action, we will develop photonic quantum network, which consists of highly correlated large-scale quantum network involving both aspects of non-classical light: squeezed light and single photon, for scalable quantum information processing. By exploiting the intrinsic multimode structure of an ultrafast frequency comb, a quantum network supporting multiple quantum systems will be generated, and quantum correlations in the network will be optimized to readily conduct a given quantum information task. To benefit from genuine speedup of quantum information processing, single-photon control will be incorporated: single-photon subtraction and single-photon addition is applied on the quantum network. Importantly, the single photon control will be engineered to affect only specific modes of interest out of multiple frequency modes in the quantum network. The resultant light field becomes PhotonIc QUAtum NeTwork with an ultrafast frequency comb (PIQUANT), and its distinctive features will be characterized and exploited for quantum computing.
