abstract
Hybrid quantum-classical algorithms have drawn much attention because of their potential to realize the "quantum advantage" in noisy, intermediate-scale quantum (NISQ) devices. Here we introduce QRunes, a cross-platform quantum language for hybrid programming. QRunes can be compiled to various host backends, allowing the user to write portable quantum subprograms. The hybrid programming is based on the type system, which is used to decide where a statement should be run. We also introduce Qurator, a VSCode plugin that has QRunes language support and two host backends.

An Improved Quantum Algorithm of the Multislice Method
The authors rebuild the phase-shifting circuit of their quantum multislice algorithm using Walsh functions, removing multi-controlled gates and adding an error-controlled truncation that cuts gate count by over an order of magnitude.
