Towards the Heisenberg limit in microwave photon detection by a qubit array

Quantum Physics 2021-06-02 v3 Superconductivity

Abstract

Using an analytically solvable model, we show that a qubit array-based detector allows to achieve the fundamental Heisenberg limit in detecting single photons. In case of superconducting qubits, this opens new opportunities for quantum sensing and communications in the important microwave range.
