Há 4 dias · Modern physics has developed quantum field theory (QFT) to understand the fundamental interactions between matter and forces, it treats every single point of space as a quantum harmonic oscillator. According to QFT the universe is made up of matter fields, whose quanta are fermions (i.e. leptons and quarks), and force fields, whose ...
Há 1 dia · Identifying cryptographic systems that may be secure against quantum algorithms is an actively researched topic under the field of post-quantum cryptography. [77] [78] Some public-key algorithms are based on problems other than the integer factorization and discrete logarithm problems to which Shor's algorithm applies, like the McEliece cryptosystem based on a problem in coding theory .
Há 22 horas · Electron–phonon coupling is crucial for the existence of various phases of matter, in particular superconductivity and density waves. Here, we devise a theory that incorporates the quantum ...
Há 3 dias · In theoretical physics, quantum nonlocality refers to the phenomenon by which the measurement statistics of a multipartite quantum system do not allow an interpretation with local realism. Quantum nonlocality has been experimentally verified under a variety of physical assumptions.
Há 4 dias · This project will provide new tools to study the dynamical properties of quantum systems at strong coupling. These will enhance our knowledge of quantum field theory and help us in our quest to understand many physical phenomena. Additionally this program will explore new connections between Physics and Mathematics.
Há 5 dias · 22 May 2024. Entanglement is a key part of quantum computing. Bartlomiej K. Wroblewski/Alamy. While scientists generally try to find sensible explanations for weird phenomena, quantum entanglement ...
Há 5 dias · We call this protocol bias-field digitized counterdiabatic quantum optimization (BF-DCQO). Designed to effectively tackle large-scale combinatorial optimization problems, BF-DCQO demonstrates resilience against the limitations posed by the restricted coherence times of current quantum processors and shows clear enhancement even in the presence of noise.
