Does entanglement enhance single-molecule pulsed biphoton spectroscopy?
Aiman Khan, Francesco Albarelli, Animesh Datta
It depends. For a single molecule interacting with one mode of a biphoton probe, we show that the spectroscopic information has three contributions, only one of which is a genuine…
Accreditation of Analogue Quantum Simulators
Andrew Jackson, Theodoros Kapourniotis, Animesh Datta
We present an accreditation protocol for analogue, i.e., continuous-time, quantum simulators. For a given simulation task, it provides an upper bound on the variation distance betw…
Extracting electromagnetic signatures of spacetime fluctuations
B. Sharmila, Sander M. Vermeulen, Animesh Datta
We present a formalism to discern the effects of fluctuations of the spacetime metric on electromagnetic radiation. The formalism works via the measurement of electromagnetic field…
Fundamental limits of pulsed quantum light spectroscopy: Dipole moment estimation
Francesco Albarelli, Evangelia Bisketzi, Aiman Khan +1
We study the fundamental limits of the precision of estimating parameters of a quantum matter system when it is probed by a travelling pulse of quantum light. In particular, we foc…
Partition Function Estimation: Quantum and Quantum-Inspired Algorithms
Andrew Jackson, Theodoros Kapourniotis, Animesh Datta
We present two algorithms, one quantum and one classical, for estimating partition functions of quantum spin Hamiltonians. The former is a DQC1 (Deterministic quantum computation w…
Advantage of Coherent States in Ring Resonators over Any Quantum Probe Single-Pass Absorption Estimation Strategy
Alexandre Belsley, Euan J. Allen, Animesh Datta +1
Quantum states of light have been shown to enhance precision in absorption estimation over classical strategies. By exploiting interference and resonant enhancement effects, we sho…
