Achieving the Heisenberg limit in quantum metrology using quantum error correction
The possibility to reach Heisenberg-limited quantum measurements in the presence of noise is a long-standing problem. Here, the authors derive a necessary and sufficient condition on the noise acting on any finite-dimensional probe to establish whether the Heisenberg limit is reachable using quantum...

| Sumario: | The possibility to reach Heisenberg-limited quantum measurements in the presence of noise is a long-standing problem. Here, the authors derive a necessary and sufficient condition on the noise acting on any finite-dimensional probe to establish whether the Heisenberg limit is reachable using quantum error correction. |
