Abstract:In this talk I will discuss our effort to design and modelize realistic microwave links between quantum computers, such as those created by the Wallraff group at ETH [1]. The talk will include a brief overview of the field of quantum links and recent developments, such as experiments with 64m separation [2], or coherent connections between 5 quantum processors [3]. I will also provide a simple introduction to the physics of waveguide QED and how we use quantum optics to engineer the transfer of qubits and the implementation of distributed quantum gates [4].
