26. Quantum interferometry with positrons and Positronium

Marco Giammarchi (Università degli Studi e INFN Milano (IT))

Talk

I will discuss the recent first observation of antimatter quantum interferometry with positrons and discuss the possibility of gravitational measurement with Positronium

109. Testing the Pauli Exclusion Principle with the VIP-2 Experiment and beyond

Fabrizio Napolitano

Talk

The Pauli Exclusion Principle (PEP) is one of the main cornerstones of the Quantum Theory at the basis of many phenomena, from the stability of the matter to neutron stars and from white dwarfs to superconductivity. Violation of the PEP, albeit small, could be motivated by physics beyond the known frontiers of the Standard Model which entail extra space dimensions, violation of the Lorentz...

130. Searching for signal of wave function collapse in the cosmic silence

Kristian Piscicchia (CREF, LNF (INFN))

06/09/2022, 11:00

Talk

One of the main conundrums of physics is the quantum-to-classical transition. Models of Dynamical wave function Collapse (DCMs) explain it by a progressive reduction of the quantum superposition, proportional to the increase in mass of the system under consideration. Gravity-related collapse models, like the one developed by Diosi and Penrose (DP), aroused growing interest in the last decades,...

65. Mirror modular cloning and fast quantum associative retrieval

Maria Cristina Diamantini Trugenberger (Universita e INFN, Perugia (IT))

06/09/2022, 16:30

Talk

I will show that a quantum state can be perfectly cloned up to global mirroring with a unitary transformation that depends on one single parameter. This is equivalent to “perfect” cloning for quantum associative memories which, as a consequence efficiently hold exponentially more information than their classical counterparts. I will present a probabilistic quantum associative retrieval...

100. Quantum entangled beams to improve the sensitivity of gravitational wave interferometers

Valeria Sequino

Talk

Vacuum fluctuations of the electromagnetic field are responsible for quantum noise in interferometric gravitational wave detectors.
The injection of squeezed vacuum states represents an effective solution to reduce it as it has been demonstrated first in GEO600 and afterwards in Advanced Virgo and Advanced LIGO, where it contributed to improve the detector sensitivity above 200 Hz by...

71. Application of Quantum Machine Learning to HEP Analysis at LHC using Quantum Computer Simulators and Quantum Computer Hardware – Challenges and Opportunities

Rui Zhang (University of Wisconsin Madison (US))

07/09/2022, 16:50

Talk

Machine learning enjoys widespread success in High Energy Physics (HEP) analysis at LHC. However the ambitious HL-LHC program will require much more computing resources in the next two decades. Quantum computing may offer speed-up for HEP physics analysis at HL-LHC, and can be a new computational paradigm for big data analysis in High Energy Physics.

We have successfully employed...

64. Observation and exploitation of quantum discord in many-body systems

Igor Yurkevich

09/09/2022, 11:00

Talk

Quantum correlations between parts of a composite system most clearly reveal themselves through entanglement. Designing, maintaining, and controlling entangled systems is very demanding, which raises the stakes for understanding the efficacy of entanglement-free, yet quantum, correlations, exemplified by quantum discord. Discord is defined via conditional mutual entropies of parts of a...

104. Broadband Quantum Noise reduction in a small-scale suspended interferometer

Sibilla Di Pace

09/09/2022, 11:20

Talk

Quantum noise (QN), due to the contribution of Shot Noise (SN) and Radiation Pressure Noise (RPN), is one of the major limiting contributions to the sensitivity of ground-based Gravitational Waves (GW) detectors, such as Virgo and LIGO.
Frequency-independent squeezing (FIS) setups, introduced prior to the latest observing run O3, where proven to reduce QN in the high-frequency range, where...

121. Optimal control of a radiation pressure limited opto-mechanical resonator

Laura Giacoppo

09/09/2022, 11:40

Talk

The proposal of this work is the use of a highly sophisticated mechanical control for an optomechanical resonator, based on Pontryagin’s optimal control theory. The optomechanical device is a tabletop suspended interferometer designed to be radiation pressure limited in the frequency band of the ground-based gravitational waves detectors, to provide both a source of squeezed states by...

83. On the quantisation of electric charge

Kolahal Bhattacharya (Homi Bhabha Centre for Science Education)

09/09/2022, 12:00

Talk

Quantization of electric charge is one of the biggest mysteries of modern physics. In 1931, Dirac showed that this observation could be explained if there exists magnetic monopoles. However, no magnetic monopoles have been located through experimental search. In this presentation, I shall propose an alternative proof of the quantization of electric charge, based on a non-relativistic...
