Quantum metrology enhanced by repetitive quantum error correction
Thomas Unden, Priya Balasubramanian, Daniel Louzon +11
The accumulation of quantum phase in response to a signal is the central mechanism of quantum sensing, as such, loss of phase information presents a fundamental limitation. For thi…
