Accelerating ultrafast spectroscopy with compressive sensing
Sushovit Adhikari, Cristian L. Cortes, Xiewen Wen +5
Ultrafast spectroscopy is an important tool for studying photoinduced dynamical processes in atoms, molecules, and nanostructures. Typically, the time to perform these experiments…
Accelerating quantum optics experiments with statistical learning
Cristian L. Cortes, Sushovit Adhikari, Xuedan Ma +1
Quantum optics experiments, involving the measurement of low-probability photon events, are known to be extremely time-consuming. We present a new methodology for accelerating such…
Conclusive Precision Bounds for SU(1,1) Interferometers
Chenglong You, Sushovit Adhikari, Xiaoping Ma +3
In this paper, we revisit the quantum Fisher information (QFI) calculation in SU(1,1) interferometer considering different phase configurations. When one of the input modes is a va…
Orbital-angular-momentum-enhanced estimation of sub-Heisenberg-limited angular displacement with two-mode squeezed vacuum and parity detection
Jiandong Zhang, Zijing Zhang, Longzhu Cen +1
We report on an orbital-angular-momentum-enhanced scheme for angular displacement estimation based on two-mode squeezed vacuum and parity detection. The sub-Heisenberg-limited sens…
Quantum process tomography of linear and quadratically nonlinear optical systems
Kevin Valson Jacob, Anthony E. Mirasola, Sushovit Adhikari +1
A central task in quantum information processing is to characterize quantum processes. In the realm of optical quantum information processing, this amounts to characterizing the tr…
Enhanced signal-to-noise ratio in Hanbury Brown Twiss interferometry by parametric amplification
Xiaoping Ma, Chenglong You, Sushovit Adhikari +2
The Hanbury Brown Twiss (HBT) interferometer was proposed to observe intensity correlations of starlight to measure a star's angular diameter. As the intensity of light that reache…
Sub-shot-noise-limited phase estimation via SU(1,1) interferometer with thermal states
Xiaoping Ma, Chenglong You, Sushovit Adhikari +3
We theoretically study the phase sensitivity of an SU(1,1) interferometer with a thermal state and squeezed vacuum state as inputs and parity detection as measurement. We find that…
Bounding the energy-constrained quantum and private capacities of phase-insensitive bosonic Gaussian channels
Kunal Sharma, Mark M. Wilde, Sushovit Adhikari +1
We establish several upper bounds on the energy-constrained quantum and private capacities of all single-mode phase-insensitive bosonic Gaussian channels. The first upper bound, wh…
Multiparameter estimation with single photons
Chenglong You, Sushovit Adhikari, Yuxi Chi +8
It was suggested in Ref. [Phys. Rev. Lett. 114, 170802] that optical networks with relatively inexpensive overhead---single photon Fock states, passive optical elements, and single…
