In recent years, there is a growing interest in employing ideas andexperimental techniques most commonly associated with quantuminformation processing applications, such as quantum computing orquantum communication, to improve sensitivity of metrologicalprotocols. Advantages of utilizing squeezed states of light havealready been demonstrated in gravitational wave detectors, quantumion manipulation techniques, developed with quantum computingapplications in mind, have been employed in the so called quantumlogic spectroscopy, while NV centers have been used to performmagnetic field sensing with sensitivity enhanced thanks to the useof quantum error-correction techniques. The talk will discuss theserecent experimental advances as well as provide theoreticalfoundations laying behind them.
