Quantum
Series
Building a Quantum CompilerA small optimizing compiler for quantum circuits, built from the IR up: OpenQASM 3 in, optimized QIR out, executed on CUDA-Q, and measured against the Qiskit and pytket transpilers.One GPU, N QubitsHow far quantum simulation goes on one consumer graphics card. cuQuantum, the memory wall, and the escape routes past it. Measured honestly, on a desk, no cluster in sight.
