Quantum interconnects and modular computing

Modular architectures with atoms in tweezers

Quantum networks leverage the principles of quantum mechanics to enable secure and efficient data transmission. Unlike classical networks, which rely on conventional methods of data transfer, quantum networks utilize phenomena such as entanglement and superposition for the connection of geographically dispersed users and the sharing of quantum bits (qubits) with inherent security features. The successful realization of quantum networks not only facilitates secure communication between nodes but also opens avenues for modular quantum computation, enhancing scalability and increasing computational power. This modular approach allows multiple quantum processors to work together, effectively expanding the computational resources available for complex tasks. Quantum interconnects, devices that allow to connect a quantum system to a classical one, are a key element of modular systems and all conceivable future quantum information processing architectures.

Modular architectures equipped with quantum interconnects are foundational to unlocking the full potential of quantum technologies. In quantum computing, modular architectures linked by interconnects offer the most practical path to millions of error-corrected qubits for tackling classically intractable problems. In quantum communication, interconnects enable the creation of quantum networks that leverage the principles of quantum mechanics to ensure "future-proof" security against even the most advanced quantum computers. Quantum interconnects enhanced with repeaters (devices that can relay entangled states over a distance) can overcome the exponential transmission losses in optical fibers, vastly extending the network reach. Beyond these domains, quantum interconnects and modular systems are critical for enhanced quantum sensing.

In this lab we envision the realization of a modular architecture based on the unique capabilities of 171Yb atoms trapped in optical tweezers. This architecture features programmable qubit control, uninterrupted operations and a quantum interconnect providing atom-photon entanglement generation mediated by an optical cavity.
