Summary:Quantum hardware is experiencing a boon leading to more chip variety and configurations with higher fidelities. While ultimately, this will translate to a boon for the entire field of quantum computing, it presents a software design problem by placing more of the overall burden of realizing end-to-end quantum applications on the software stacks, specifically the quantum compiler. The Berkeley Quantum Synthesis Toolkit (BQSKit) is a powerful and portable quantum compiler framework with a proven ability to alleviate this issue and translate recent hardware successes up to the algorithm level. BQSKit achieves superior portability and optimization potential by utilizing a parameterized quantum circuit intermediate representation to facilitate numerical instantiation.

In this talk and demonstration, Ed will first introduce the idea of numerical instantiation and BQSKit compilation, including algorithms and workflows for transpiling circuits to any hardware, even ones with heterogeneous gate sets or higher-level qudits (qutrits). Ed then details several further practical use cases, such as error mitigation techniques with approximations and algorithm-hardware design exploration.

Bio:Ed Younis is a computer systems engineer at Lawrence Berkeley National Laboratory with extensive experience developing and implementing advanced algorithms for quantum compilation,such as QFAST and Qfactor. He is currently the principal engineer on the BQSKit project and has research interests in quantum synthesis, compilation, and software systems.

Moderators: Pawel Gora, CEO of Quantum AI Foundation and Dr. Sebastian Zajac, member of QPoland

Can you try some later versions of Lombok, such as version 1.18.2?

Yes. Deploying Spring Boot application to AWS for scalability is not dealing with the web server. But I think nowadays, deploying applications to the cloud is the way to handle a large number of requests.

I think deploying applications to web server is a small enterprise solution.

I think developers nowadays can deploy their applications to AWS instances in order to make the application more scalable, which means accepting many requests from users.

Or, you can create application-test.properties or yml file under a new folder called resources under test folder.
In the test code , add @TestPropertySource like this:

This way, the port from the application-test.properties or yml will be read.

First of all, the problem is your test cannot read the port number. I created a simple Spring Boot project that is similar to yours. The simplified version of my demo project is trying to isolate other irrelevant code.

In your src/main/resources/ folder, add this property to your application.properties or yaml file:

I ran the FleDownloadControllerTest and the 1234 can be printed during the test.

The schema.sql is not required unless you want to customize how to build the tables.
Here is the tutorial:  https://www.baeldung.com/spring-boot-data-sql-and-schema-sql

If your computer has 8 cores and your application has 8 threads, each core will handle each thread.
There is no guarantee which thread will complete first , second , third and etc.
Is it because the other project is using Spring Boot 2 and it accepts java.persistence?
It does not matter if a class is anonymous or not. During runtime, the Java runtime environment will create an instance for that class.

I read the article you provided.
To my understanding, the two inner join queries can be executed in parallel and then the intermediate results are joined. It is a divide-and-conquer approach.
The inner join with the Or statement is executed sequentially. That explains why the inner join with the or expression takes a longer time, 11 minutes.
Any Spring Framework or Spring Boot books are fine. You may want to read multiple books for more information. For the first time I learn Spring, I read Getting Started with Spring Framework (Cover Spring Framework 5) , Forth edition , by J Sharma.

The basic concepts of Spring Framework 5 and 6 are the same.

Are you using Maven as the build tool for your project? If so, try to run mvn package. I think if that is a Gradle project, you can package it as well.
