Quantifying the performance of multipulse quantum sensing

نویسندگان

چکیده

The quality of a quantum operation determines the performance information processing, such as sensitivity sensing. Different from fidelity in computation, we present an effective function to evaluate and diagnose imperfection operations multi-pulse based evaluation directly links realistic with intrinsic simple way. Moreover, guided by this function, optimize composite pulse sequence for high nitrogen-vacancycenter magnetometry against spectrum inhomogeneities control errors improve signal-to-noise ratio nanoscale nuclear magnetic resonance 1 order magnitude. It marks important step towards quantitative sensing imperfect practical applications.

Quantifying the Performance of Quantum Codes

We study the properties of error correcting codes for noise models in the presence of asymmetries and/or correlations by means of the entanglement fidelity and the code entropy. First, we consider a dephasing Markovian memory channel and characterize the performance of both a repetition code and an error avoiding code (CRC and CDFS, respectively) in terms of the entanglement fidelity. We also c...

Multipulse quantum control: exact solutions.

The coherent propagation of four optical pulses through a multilevel resonant medium is investigated theoretically. We present a self-consistent analytic solution without steady-state or adiabatic approximations and use numerical simulations to indicate that the analytic formulas can be used as a guide in an experimental setting.

Single-spin magnetometry with multipulse sensing sequences.

We experimentally demonstrate single-spin magnetometry with multipulse sensing sequences. The use of multipulse sequences can greatly increase the sensing time per measurement shot, resulting in enhanced ac magnetic field sensitivity. We theoretically derive and experimentally verify the optimal number of sensing cycles, for which the effects of decoherence and increased sensing time are balanc...
