Quantum Computing for High-Energy Physics: State of the Art and Challenges [PDF]
PRX Quantum, 2023 Quantum computers offer an intriguing path for a paradigmatic change of computing in the natural sciences and beyond, with the potential for achieving a so-called quantum advantage—namely, a significant (in some cases exponential) speedup of numerical ...

Quantum automata and quantum grammars
Theoretical Computer Science, 2000 To study quantum computation, it might be helpful to generalize structures from language and automata theory to the quantum case. To that end, we propose quantum versions of finite-state and push-down automata, and regular and context-free grammars. We find analogs of several classical theorems, including pumping lemmas, closure properties, rational ...

Quantum Dissipation and Quantum Groups [PDF]
Annals of Physics, 1995 We discuss the r le of quantum deformation of Weyl-Heisenberg algebra in dissipative systems and finite temperature systems. We express the time evolution generator of the damped harmonic oscillator and the generator of thermal Bogolubov transformations in terms of operators of the quantum Weyl-Heisenberg algebra. The quantum parameter acts as a label

Quantum Logic for Quantum Computers
International Journal of Theoretical Physics, 2000 The following results obtained within a project of finding algebra of states in a general purpose quantum computer are reported: 1. all operations of an orthomodular lattice, including the identity, are five-fold defined ; 2. there are non-orthomodular models for both quantum and classical logics ; 3.

Quantum-Hall quantum bits [PDF]
Physical Review B, 2002 Bilayer quantum-Hall systems can form collective states in which electrons exhibit spontaneous interlayer phase coherence. We discuss the possibility of using bilayer quantum dot many-electron states with this property to create two-level systems that have potential advantages as quantum bits.

A variational eigenvalue solver on a photonic quantum processor [PDF]
Nature Communications, 2013 Quantum computers promise to efficiently solve important problems that are intractable on a conventional computer. For quantum systems, where the physical dimension grows exponentially, finding the eigenvalues of certain operators is one such intractable
