Defects in Quantum Computers [PDF]
Scientific Reports, 2018 AbstractThe shift of interest from general purpose quantum computers to adiabatic quantum computing or quantum annealing calls for a broadly applicable and easy to implement test to assess how quantum or adiabatic is a specific hardware. Here we propose such a test based on an exactly solvable many body system–the quantum Ising chain in transverse ...

Programming gate-based hardware quantum computers for music [PDF]
Muzikologija, 2018 There have been significant attempts previously to use the equations of quantum mechanics for generating sound, and to sonify simulated quantum processes. For new forms of computation to be utilized in computer music, eventually hardware must be

Universality in quantum computation [PDF]
Proceedings of the Royal Society of London. Series A: Mathematical and Physical Sciences, 1995 We show that in quantum computation almost every gate that operates on two or more bits is a universal gate. We discuss various physical considerations bearing on the proper definition of universality for computational components such as logic gates.

Complete 3-Qubit Grover search on a programmable quantum computer
Nature Communications, 2017 Grover’s algorithm provides a quantum speedup when searching through an unsorted database. Here, the authors perform it on 3 qubits using trapped ions, demonstrating two methods for marking the correct result in the algorithm’s oracle and providing data ...

Evaluating Energy Differences on a Quantum Computer with Robust Phase Estimation. [PDF]
Physical Review Letters, 2020 We adapt the robust phase estimation algorithm to the evaluation of energy differences between two eigenstates using a quantum computer. This approach does not require controlled unitaries between auxiliary and system registers or even a single auxiliary

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 HOLONOMIES FOR QUANTUM COMPUTING [PDF]
International Journal of Modern Physics B, 2001 Holonomic Quantum Computation (HQC) is an all-geometrical approach to quantum information processing. In the HQC strategy information is encoded in degenerate eigen-spaces of a parametric family of Hamiltonians. The computational network of unitary quantum gates is realized by driving adiabatically the Hamiltonian parameters along loops in a control ...
