Finite-time quantum entanglement in propagating squeezed microwaves
(Nature Publishing, 2018-04-23)
Two-mode squeezing is a fascinating example of quantum entanglement manifested in cross-correlations of non-commuting observables between two subsystems. At the same time, these subsystems themselves may contain no quantum ...
A journey across dopamine Metabolism: A rotational study of DOPAC
(Elsevier, 2023-04)
DOPAC, a relevant scaffold in dopamine metabolism, was probed in the gas phase and interrogated by high-resolution rotational spectroscopy. Herein, three distinct conformers were isolated in a supersonic jet and identified ...
Co-Design quantum simulation of nanoscale NMR
(American Physical Society, 2022-11)
Quantum computers have the potential to efficiently simulate the dynamics of nanoscale NMR systems. In this work, we demonstrate that a noisy intermediate-scale quantum computer can be used to simulate and predict nanoscale ...
Portfolio optimization with digitized counterdiabatic quantum algorithms
(American Physical Society, 2022-12)
We consider digitized-counterdiabatic quantum computing as an advanced paradigm to approach quantum advantage for industrial applications in the NISQ era. We apply this concept to investigate a discrete meanvariance portfolio ...
A neural network assisted 171Yb+ quantum magnetometer
(Nature, 2022-12)
A versatile magnetometer must deliver a readable response when exposed to target fields in a wide range of parameters. In this work, we experimentally demonstrate that the combination of(171)Yb(+) atomic sensors with ...
Quantum-enhanced Doppler lidar
(Nature, 2022-12)
We propose a quantum-enhanced lidar system to estimate a target’s radial velocity, which employs squeezed and frequency-entangled signal and idler beams. We compare its performance against a classical protocol using a ...
Quantum Rabi dynamics of trapped atoms far in the deep strong coupling regime
(Nature, 2023-02)
The coupling of a two-level system with an electromagnetic field, whose fully quantized version is the quantum Rabi model, is among the central topics of quantum physics. When the coupling strength becomes large enough ...
Using the Synergy between HPLC-MS and MALDI-MS Imaging to Explore the Lipidomics of Clear Cell Renal Cell Carcinoma
(American Chemical Society, 2023-01)
Lipid imaging mass spectrometry (LIMS) has been tested in several pathological contexts, demonstrating its ability to segregate and isolate lipid signatures in complex tissues, thanks to the technique’s spatial resolution. ...
Beyond the Light-Cone Propagation of Relativistic Wavefunctions: Numerical Results
(MDPI, 2023-02-06)
It is known that relativistic wavefunctions formally propagate beyond the light cone when the propagator is limited to the positive energy sector. By construction, this is the case for solutions of the Salpeter (or ...
A Competition between Relative Stability and Binding Energy in Caffeine Phenyl-Glucose Aggregates: Implications in Biological Mechanisms
(MDPI, 2023-02-23)
Hydrogen bonds and stacking interactions are pivotal in biological mechanisms, although their proper characterisation within a molecular complex remains a difficult task. We used quantum mechanical calculations to characterise ...
