 Quantum computers offer a new avenue for studying and probing phenomena in (and possibly beyond) physics. But current devices, largely due to noise, are limited in scalability and accuracy—so what should we do? Should we just wait for fault tolerance, or is there anything we can learn from today’s devices in the meantime? The latter option is explored through the lens of quantum middleware, an aspect of quantum computing that connects high-level algorithms to their physical implementation. In this talk, motivated by my time as an intern at Haiqu during the PSI two-year program, I will introduce quantum middleware and demonstrate how its optimization can offset some of the issues presented by current devices, highlighted by the use of SU(2)-symmetric circuits to study frustrated quantum systems.
