Optimizing QUBO on a quantum computer by mimicking imaginary time evolution
Yahui Chai, Alice Di Tucci
We propose a hybrid quantum-classical algorithm for solving QUBO problems using an Imaginary Time Evolution-Mimicking Circuit (ITEMC). The circuit parameters are optimized to close…
Quantum convolutional neural networks for jet images classification
Hala Elhag, Tobias Hartung, Karl Jansen +3
Recently, interest in quantum computing has significantly increased, driven by its potential advantages over classical techniques. Quantum machine learning (QML) exemplifies one of…
Path integrals, saddle points and the beginning of the universe
Alice Di Tucci
The very early universe is understood in terms of quantum field theories on curved spacetime, where the classical background spacetime is typically an FLRW cosmology and the quantu…
Lessons for quantum cosmology from anti-de Sitter black holes
Alice Di Tucci, Michal P. Heller, Jean-Luc Lehners
Gravitational physics is arguably better understood in the presence of a negative cosmological constant than a positive one, yet there exist strong technical similarities between t…
No-boundary prescriptions in Lorentzian quantum cosmology
Alice Di Tucci, Jean-Luc Lehners, Laura Sberna
We analyse the impact of various boundary conditions on the (minisuperspace) Lorentzian gravitational path integral. In particular we assess the implications for the Hartle-Hawking…
Homogeneous Transitions during Inflation: a Description in Quantum Cosmology
Sebastian F. Bramberger, Alice Di Tucci, Jean-Luc Lehners
The usual description of inflationary fluctuations uses the framework of quantum field theory (QFT) in curved spacetime, in which quantum fluctuations are superimposed on a classic…
Quantum Incompleteness of Inflation
Alice Di Tucci, Job Feldbrugge, Jean-Luc Lehners +1
Inflation is most often described using quantum field theory (QFT) on a fixed, curved spacetime background. Such a description is valid only if the spatial volume of the region con…
The No-Boundary Proposal as a Path Integral with Robin Boundary Conditions
Alice Di Tucci, Jean-Luc Lehners
Realising the no-boundary proposal of Hartle and Hawking as a consistent gravitational path integral has been a long-standing puzzle. In particular, it was demonstrated by Feldbrug…
