Deliverables
In this deliverable we will report on the design of basic superconducting qubits and tuneable couplers modelling realistic effects of crosstalk and decoherence With this information we will elaborate realistic implementations of variational quantum algorithms and their feasibility for implementation using the proposed hardwareWe will also report on the progress in building a classical simulator using a supercomputer
Fabrication of 5-qubit quantum annealing demonstratorIn this deliverable we will report on the production of a lowimpedance 5qubit device being the baseline for benchmarking experiments in WP3 following extensive design and simulation using feedback from task 41 This annealer will contain a qubit network with 10 rfSQUIDtype couplers The flux qubits will be optimized for QA with capacitiveshunting
Optimized design for multi-qubit and non-stoquastic couplersIn this deliverable we will report on designs and simulations to produce circuits that generate a twobody interaction of the type XX known as nonstoquastic or nonIsing as well as circuits that generate a multiqubit coupling term beyond 2 qubits
Project Management and Quality GuidelinesIn this deliverable we will document administrative project management procedures quality assurance and risk managementThe report will include description of communication channels between all partners as well as defining and maintaining internal collaborative tools for sharing documentation and communicating work status One of the outcomes will be a Project Portal shared workspace that will be updated throughout the project and a project logo
Operational wideband parametric amplifier for QAIn this deliverable we will report on the production of an optimized traveling wave parametric amplifier TWPA to obtain an easytouse device and validated using multiqubit devices fabricated by UG Optimization of the readout efficiency for strongly anharmonic qubits such as flux and fluxoniumtype qubits will be carried out Figures of merit such as readout efficiency and crosstalk will be quantified
Prototype of CQA with high impedance circuitsIn this deliverable we will report on the production and characterization of highimpedance coherent quantum annealers using fluxoniumtype qubits and their use in quantum annealing applications
In this deliverable following the Open Research Data Pilot we will document the lifecycle for all data sets collected processed and generated by AVaQus The data management plan will evolve along the project outlining data handling during and after the project what data will be collected following what methodology and what standards and whether it will be made open and how it will be preserved
Publish project website using eu domain to disseminate project activities results news etc The portal will also be used to announce job offers
