Reducing resources for verification of quantum computations
We present two verification protocols where the correctness of a "target"
computation is checked by means of "trap" computations that can be efficiently
simulated on a classical computer. Our protocols rely on a minimal set of
noise-free operations (preparation of eight single-qubit states or measurement
of four observables, both on a single plane of the Bloch sphere) and achieve
linear overhead. To the best of our knowledge, our protocols are the least
demanding techniques able to achieve linear overhead. They represent a step
towards further reducing the quantum requirements for verification.Comment: Accepted versio
Understanding Quantum Technologies 2022
Understanding Quantum Technologies 2022 is a creative-commons ebook that
provides a unique 360 degrees overview of quantum technologies from science and
technology to geopolitical and societal issues. It covers quantum physics
history, quantum physics 101, gate-based quantum computing, quantum computing
engineering (including quantum error corrections and quantum computing
energetics), quantum computing hardware (all qubit types, including quantum
annealing and quantum simulation paradigms, history, science, research,
implementation and vendors), quantum enabling technologies (cryogenics, control
electronics, photonics, components fabs, raw materials), quantum computing
algorithms, software development tools and use cases, unconventional computing
(potential alternatives to quantum and classical computing), quantum
telecommunications and cryptography, quantum sensing, quantum technologies
around the world, quantum technologies societal impact and even quantum fake
sciences. The main audience are computer science engineers, developers and IT
specialists as well as quantum scientists and students who want to acquire a
global view of how quantum technologies work, and particularly quantum
computing. This version is an extensive update to the 2021 edition published in
October 2021.Comment: 1132 pages, 920 figures, Letter forma
