From virtual Z gates to virtual Z pulses
Virtual $Z$ gates have become integral for implementing fast, high-fidelity single-qubit operations. However, virtual $Z$ gates require that the system's two-qubit gates are microwave-activated or nor...

Ever wanted to use virtual Z gates with arbitrary powers of SWAP? Introducing the virtual Z pulse: arxiv.org/abs/2509.13453. In our new article, we present a method for distorting a pulse sequence to implement single-qubit Z controls virtually.

With a long transfer from the Sahara to Fes, I finally finished going through the starter packs below. It was great to see everything you all have been working on! I like to spend some time reading through each profile, so I start to remember who's working on what. Please comment more starter packs!

Last academic year, I reviewed my first paper. To any other PhD student considering whether to accept or decline this opportunity: I found it insightful to be on the other side of the process. It will help me anticipate future reviewer questions and prepare responses.

How fast can quantum processors run? My coauthors and I answer in our new npj Quantum Information article! Utilising pulse engineering, we prepare molecular ground states in a few nanoseconds, ~100× faster than with gates. Back-of-the-envelope: Simulations can now tolerate T₁ and T₂ ~100× smaller.

Hi all! I am excited to finally share this suite of quantum optimal control libraries that run up to 100× faster than QuTiP for some tasks. We developed these libraries while working on our preprint arxiv.org/abs/2406.10913, which was recently accepted into npj Quantum Information—keep tuned!

Hi! Those who know me might be surprised to see me here—I’m something of a social media hermit. However, academia has taught me the value of connecting with the community, so I’m giving this a go. I’m excited to share my work and hear your thoughts, and I look forward to collaborating with you!
