Heisenberg-limited single-mode quantum metrology in a superconducting circuit

Heisenberg-limited single-mode quantum metrology in a superconducting circuit

Reaching a quantum advantage in metrology usually requires hard-to-prepare two-mode entangled states such as NOON states. Here, instead, the authors demonstrate single-mode phase estimation using Fock states superpositions in a superconducting qubit-oscillator system.
