Quantum Computing is getting more and more attention. While the commercial availability of real, general-purpose hardware is still limited, the potential is huge, in many areas including encryption, optimisation, chemistry, and physics. Quantum Computers need to be programmed, similar to how classical computers are programmed.

In this session, we explain the major differences between classical computing and quantum computing. We discuss how Java can be used to create quantum applications, and we talk about potential improvements in Java bytecode that could leverage quantum concepts. Most quantum computing software research currently uses quantum simulators, where a real quantum computer is simulated using a classical computer. This creates major challenges related to memory and computing resources. We will discuss how improvements in project Panama, or using Records can improve the performance of Java for quantum computing simulators.
