Mitigating radiation damage of single photon detectors for space applications
EPJ Quantum Technology, 2017 Single-photon detectors in space must retain useful performance characteristics despite being bombarded with sub-atomic particles. Mitigating the effects of this space radiation is vital to enabling new space applications which require high-fidelity ...

T-count and T-depth of any multi-qubit unitary
npj Quantum Information, 2022 We design an algorithm to determine the (minimum) T-count of any n-qubit (n ≥ 1) unitary W of size 2 n × 2 n , over the Clifford+T gate set. The space and time complexity of our algorithm are $$O\left({2}^{2n}\right)$$ O 2 2 n and $$O\left({2}^{2n ...

, 1997 We describe how physics of computation determines computational complexity. In particular we show how quantum phenomena lead to qualitatively new modes of computation. An ideal quantum computer would allow to face certain tasks out of reach of classical computers, the factorization problem being the most striking example.

Probing the strongly driven spin-boson model in a superconducting quantum circuit
Nature Communications, 2018 Two-level systems interacting with a bosonic environment appear everywhere in physics. Here, the authors use a superconducting device to study this spin-boson model in the presence of coherent driving, showing that the drive enhances dissipation into the

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 ...

Investigations in Quantum Computing: Causality and Graph Isomorphism [PDF]
, 2004 In this thesis I explore two different types of limits on the time complexity of quantum computation---that is, limits on how much time is required to perform a given class of quantum operations on a quantum system. Upper limits can be found by explicit

Adiabatic Quantum Computation is Equivalent to Standard Quantum Computation [PDF]
45th Annual IEEE Symposium on Foundations of Computer Science, 2004 Adiabatic quantum computation has recently attracted attention in the physics and computer science communities, but its computational power was unknown. We describe an efficient adiabatic simulation of any given quantum algorithm, which implies that the adiabatic computation model and the conventional quantum computation model are polynomially ...

Deep neural network analysis models for complex random telegraph signals
Scientific Reports, 2023 Time-fluctuating signals are ubiquitous and diverse in many physical, chemical, and biological systems, among which random telegraph signals (RTSs) refer to a series of instantaneous switching events between two discrete levels from single-particle ...
