Einstein Research Unit "Quantum Devices"
Berlin University Alliance joint project
Perspectives of a quantum digital transformation
How can quantum computers revolutionize the computational power of computers? What new insights do quantum computers offer for high energy physics or quantum chemistry? These are the questions that the first Einstein Research Unit (ERU) of the Berlin University Alliance (BUA) will address. The interdisciplinary research team of the partner institutions Freie Universität Berlin, Humboldt-Universität zu Berlin, Technische Universität Berlin, and Charité – Universitätsmedizin Berlin has set itself the task of clarifying the potential of the quantum digital transformation. This uniquely brings together expertise in theoretical and experimental physics, applied mathematics, computer science, and machine learning.
The Einstein Research Unit “Perspectives of a quantum digital transformation: Near-term quantum computational devices and quantum processors” will be funded with two million euros annually for an initial three years.

Sub-project P11: Generation of photonic cluster states
Photonic cluster states are the main resource for measurement-based “one-way” quantum computing. The required theoretical and experimental schemes for their generation will be developed and implemented, which will in turn be applied for the demonstration of a quantum algorithm.

Sub-project P12: Distributing quantum information with an atomic vapor-based quantum light source
In this project, we develop a novel quantum light source that emits at telecom wavelengths as a key component for quantum communication networks. The source uses a single-photon turnstile, which is based on a collectively enhanced non-linearity inside thermal Rubidium vapor – an approach radically different from other schemes. Implemented in a fiberbased proof-of-principle quantum key distribution test-bed, we evaluate the performance of the source for applications in quantum cryptography.
