Fault tolerance for holonomic quantum computation

open access: yes, 2013
We review an approach to fault-tolerant holonomic quantum computation on stabilizer codes. We explain its workings as based on adiabatic dragging of the subsystem containing the logical information around suitable loops along which the information ...

Integrable quantum computation [PDF]

open access: yesQuantum Information Processing, 2012
Integrable quantum computation is defined as quantum computing via the integrable condition, in which two-qubit gates are either nontrivial unitary solutions of the Yang--Baxter equation or the Swap gate (permutation). To make the definition clear, in this article, we explore the physics underlying the quantum circuit model, and then present a unified ...

The simplest demonstrations of quantum nonlocality

open access: yesNew Journal of Physics, 2012
We investigate the complexity cost of demonstrating the key types of nonclassical correlations—Bell inequality violation, Einstein, Podolsky, Rosen (EPR)-steering, and entanglement—with independent agents, theoretically and in a photonic experiment.

Valley interference and spin exchange at the atomic scale in silicon

open access: yesNature Communications, 2020
Coupled donor wavefunctions in silicon are spatially resolved to evidence valley interference processes. An atomic-scale understanding of the interplay between interference, envelope anisotropy and crystal symmetries unveils a placement strategy ...

Measurement-Only Topological Quantum Computation via Anyonic Interferometry

open access: yes, 2008
We describe measurement-only topological quantum computation using both projective and interferometrical measurement of topological charge. We demonstrate how anyonic teleportation can be achieved using "forced measurement" protocols for both types of ...

Ergodic Quantum Computing [PDF]

open access: yesQuantum Information Processing, 2005
We propose a (theoretical ;-) model for quantum computation where the result can be read out from the time average of the Hamiltonian dynamics of a 2-dimensional crystal on a cylinder. The Hamiltonian is a spatially local interaction among Wigner-Seitz cells containing 6 qubits.

Quantum Genetics, Quantum Automata and Quantum Computation [PDF]

open access: yes, 2004
The concepts of quantum automata and quantum computation are studied in the context of quantum genetics and genetic networks with nonlinear dynamics. In a previous publication (Baianu,1971a) the formal concept of quantum automaton was introduced and its ...

Permutational quantum computing [PDF]

open access: yesQuantum Information and Computation, 2010
In topological quantum computation the geometric details of a particle trajectory are irrelevant; only the topology matters. Taking this one step further, we consider a model of computation that disregards even the topology of the particle trajectory, and computes by permuting particles.

Silicon quantum processor with robust long-distance qubit couplings

open access: yesNature Communications, 2017
Quantum computers will require a large network of coherent qubits, connected in a noise-resilient way. Tosi et al. present a design for a quantum processor based on electron-nuclear spins in silicon, with electrical control and coupling schemes that ...
