چکیده
A new time-domain method for subcycle metrology of quantum electric fields using a combination third order nonlinear optical process and homodyne detection with local oscillator (LO) field is proposed analyzed. The enables isolation intrinsically weak noise contribution by subtraction the shot LO on pulse-by-pulse basis. Together centro-symmetric character nonlinearity, this unlocks novel opportunities toward terahertz mid-infrared metrologies.

Advances in Quantum Metrology
In classical estimation theory, the central limit theorem implies that the statistical error in a measurement outcome can be reduced by an amount proportional to n by repeating the measures n times and then averaging. Using quantum effects, such as entanglement, it is often possible to do better, decreasing the error by an amount proportional to n. Quantum metrology is the study of those quantu...
متن کاملExponentially enhanced quantum metrology.
We show that when a suitable entanglement-generating unitary operator depending on a parameter is applied on N qubits in parallel, a precision of the order of 2(-N) in estimating the parameter may be achieved. This exponentially improves the precision achievable in classical and in quantum nonentangling strategies.
متن کاملQuantum metrology: dynamics versus entanglement.
A parameter whose coupling to a quantum probe of n constituents includes all two-body interactions between the constituents can be measured with an uncertainty that scales as 1/n3/2, even when the constituents are initially unentangled. We devise a protocol that achieves the 1/n3/2 scaling without generating any entanglement among the constituents, and we suggest that the protocol might be impl...

Information science is entering into a new era in which certain subtleties of quantum mechanics enables large enhancements in computational efficiency and communication security. Naturally, precise control of quantum systems required for the implementation of quantum information processing protocols implies potential breakthoughs in other sciences and technologies. We discuss recent development...
متن کاملQuantum metrology assisted by abstention.
The main goal of quantum metrology is to obtain accurate values of physical parameters using quantum probes. In this context, we show that abstention, i.e., the possibility of getting an inconclusive answer at readout, can drastically improve the measurement precision and even lead to a change in its asymptotic behavior, from the shot-noise to the Heisenberg scaling. We focus on phase estimatio...
