Optomechanical Anti-lasing with Infinite Group Delay at a Phase Singularity

Yulong Liu, Qichun Liu, Shuaipeng Wang +3

Singularities that symbolize abrupt changes and exhibit extraordinary behavior are of broad interest. We experimentally study optomechanically induced singularities in a compound s…

Protocol for temperature sensing using a three-level transmon circuit

Aidar Sultanov, Marko Kuzmanović, Andrey V. Lebedev +1

We present a method for in situ temperature measurement of superconducting quantum circuits, by using the first three levels of a transmon device to which we apply a sequence of $π…

Benchmarking Machine Learning Algorithms for Adaptive Quantum Phase Estimation with Noisy Intermediate-Scale Quantum Sensors

Nelson Filipe Costa, Yasser Omar, Aidar Sultanov +1

Quantum phase estimation is a paradigmatic problem in quantum sensing andmetrology. Here we show that adaptive methods based on classical machinelearning algorithms can be used to…

Linear Ascending Metrological Algorithm

M. R. Perelshtein, N. S. Kirsanov, V. V. Zemlyanov +4

The ubiquitous presence of shot noise sets a fundamental limit to the measurement precision in classical metrology. Recent advances in quantum devices and novel quantum algorithms…

Phase-controlled pathway interferences and switchable fast-slow light in a cavity-magnon polariton system

Jie Zhao, Longhao Wu, Tiefu Li +4

We study the phase controlled transmission properties in a compound system consisting of a 3D copper cavity and an yttrium iron garnet (YIG) sphere. By tuning the relative phase of…

Quantum speed limit and divisibility of the dynamical map

Jose Teittinen, Sabrina Maniscalco

The quantum speed limit (QSL) is the theoretical lower limit of the time for a quantum system to evolve from a given state to another one. Interestingly, it has been shown that non…
