Optimal Estimation of Quantum Coherence by Bell State Measurement: A Case Study [PDF]

open access: yesEntropy, 2023
Quantum coherence is the most distinguished feature of quantum mechanics. As an important resource, it is widely applied to quantum information technologies, including quantum algorithms, quantum computation, quantum key distribution, and quantum ...

One classical bit perspective on the noisy teleportation of quantum coherence [PDF]

open access: yesScientific Reports
Quantum teleportation of an unknown quantum state necessitates the transmission of two classical bits of information; however, when the quantum state is partially known, only a single classical bit is required for the teleportation of its quantum ...

Photodiode-based time zero determination for ultrafast electron microscopy

open access: yesStructural Dynamics, 2023
Pump-probe experiments in ultrafast electron microscopy require temporal overlap between the pump and probe pulses. Accurate measurements of the time delay between them allows for the determination of the time zero, the moment in time where both pulses ...

RF acceleration of ultracold electron bunches

open access: yesStructural Dynamics, 2023
The ultrafast and ultracold electron source, based on laser cooling and trapping of atomic gas and its subsequent near-threshold two-step photoionization, is capable of generating electron bunches with a high transverse brightness at energies of roughly ...

Collisional microwave heating and wall interaction of an ultracold plasma in a resonant microwave cavity

open access: yesNew Journal of Physics, 2022
Recently, we introduced a resonant microwave cavity as a diagnostic tool for the study of ultracold plasmas (UCPs). This diagnostic allows us to study the electron dynamics of UCPs non-destructively, very fast, and with high sensitivity by measuring the ...

Parameterized coherence measure

open access: yesResults in Physics, 2023
Quantifying coherence is an essential endeavor for both quantum mechanical foundations and quantum technologies. We present a bona fide measure of quantum coherence by utilizing the Tsallis relative operator (α,β)-entropy.

Quantum nonlinear spectroscopy of single nuclear spins

open access: yesNature Communications, 2022
Signals that look the same from their low-order correlations can often be distinguished by looking at higher-order ones. Here, the authors exploit the sensitivity of quantum nonlinear spectroscopy to fourth-order correlations to identify Gaussian noises,

Robustness of quantum coherence and quantum criticality in spin-1 many-body system

open access: yesPhysics Open, 2023
The tripartite quantum coherence for spin-12 and bipartite quantum coherence for spin-1 many-body systems are studied with the quantum renormalization group method to investigate the quantum criticality behaviour of both systems. We find both spin-12 and
