Practical quantum metrology with large precision gains in the low photon number regime
Quantum metrology exploits quantum correlations to make precise measurements with limited particle numbers. By utilizing interand intramode correlations in an optical interferometer, we find a state that combines entanglement and squeezing to give a 7-fold enhancement in the quantum Fisher information (QFI) – a metric related to the precision – over the shot noise limit, for low photon numbers....
متن کاملQuantum metrology with parametric amplifier-based photon correlation interferometers
Conventional interferometers usually utilize beam splitters for wave splitting and recombination. These interferometers are widely used for precision measurement. Their sensitivity for phase measurement is limited by the shot noise, which can be suppressed with squeezed states of light. Here we study a new type of interferometer in which the beam splitting and recombination elements are paramet...
متن کاملTowards practical quantum cryptography
Quantum cryptography bases the security of quantum key exchange on the laws of quantum physics and is likely to become the first application employing quantum effects for communication. Here we present performance tests of a new design based on polarization encoding of attenuated, coherent light pulses. Our measurements show that this compact setup can achieve an effective key-bit rate in the k...
متن کاملSingle-quantum dot imaging with a photon counting camera.
The expanding spectrum of applications of single-molecule fluorescence imaging ranges from fundamental in vitro studies of biomolecular activity to tracking of receptors in live cells. The success of these assays has relied on progress in organic and non-organic fluorescent probe developments as well as improvements in the sensitivity of light detectors. We describe a new type of detector devel...
