I'm in Paris this week visiting VeriQloud! If you're working in the Paris quantum ecosystem and would like to meet up for a coffee and/or show me your awesome quantum lab, message me! I'd love to visit some of the many people working on fantastic projects around the city, despite the heat.

On a brilliant twist of fate I met the engineers running eduroam a couple of weeks ago. Felt like meeting superstars, & fun fact Helsinki is apparently not the only airport with eduroam! Others include Stockholm and Luxembourg. Even they are amazed and how well the project has gone down since 2002

New short paper exploring how variational quantum circuits (a type of QML circuit) can be either trainable, cut affordably, or non-simulable, but probably not all three. Another reason not to distribute through classical channels: scirate.com/arxiv/2607.1...

For the past 70 years, scientists have taught us that female mammals are born with a finite ovarian egg supply. In humans, that supply dwindles until menopause, when it goes bankrupt. That dogma might be utterly wrong, new research suggests. www.scientificamerican.com/article/the-...

The biological dogma that women don’t make new eggs after birth may be wrong

Female mammals have long thought to be born with all the eggs they would ever have, but new research is challenging that consensus

Coseners was great, I missed cheese and british irony. Selling quantum to a room full of classical internet & communications architects went down quite well

Such a pleasure to have participated at NUS’s HACKAMONTH this June! Beyond grateful to my co-hackers and the staff at Singapore’s Center of Quantum Tech, for an incredible month & wonderful collaborations! One of the papers written during this time is already out, but keep an eye out for more :)

I visited the first museum on the afterlife. Can now claim I have been to hell and back 😉

New pre-print: a quantum ring all-reduce, the primitive behind large-scale ML training. We cut online communication, enable info-theoretically private aggregation, & show quadratic/exponential advantages on gradient-conflict problems. scirate.com/arxiv/2606.2...

Quantum ring all-reduce: communication and privacy advantages for distributed learning

Machine learning models have scaled to unprecedented sizes, making training across distributed devices the de facto standard in the field. In this work, we explore how quantum communications can make ...

Yesterday I gave a short intro to Distributed Quantum Computing at the Center of Quantum tech in Singapore! You can check out my (20 min long) dry run here: m.youtube.com/watch?v=xUrb...

In case you doubt why would distribution be useful for compute: ~ from arxiv.org/pdf/1802.05799

It would be very nice if quantum circuit benchmarking suites like MQTBench came with expected results for the circuits in 0 noise environments so that we can test against them. It's easy enough for things like W or GHZ generators but I have no clue what your Grover implementation was converging on

Having a great time in sunny Singapore during the first week of CQT’s HACKMONTH

I find this mildly entertaining

I’ll be at the Center of Quantum Tech in the National University if Singapore t’ill late June. Reach out if you’re around!

I have a few things to plug so I guess this needs to be a thread. First: new paper! What if instead of designing quantum software with H's in boxs and of weird things, what if you just play whack-a-mole with a managable set of variables. Turns out it works! scirate.com/arxiv/2605.2...

Interested in what resource estimation for minimisation looks like in DQC? Well I have a new blog post: grageragarces.github.io/dqc_articles...

1/2 After a week of causality lectures and explanations over sake and whiskey I think I’m starting to get it:

Lovely ride to the Isle of Skye today for the QI spring school

QuNAP group at the end of the day. A few people are missing, but this is a good chunk of attendees. #IEEE #INFOCOM #INFOCOM2026

Landed in Tokyo! First time in Asia (and thus also Japan). Quite excited and tired from the flight!

Recent work were Majid Haghparast and I explore how the optimisation of quantum circuits behaves when implemented before and after partitioning in a standard compiler pipeline for distributed quantum computing: arxiv.org/pdf/2605.02727 Will be presented at DisQIC within ICDCS this summer.

I made it to the Nova 111 student list this year! The list recognises the top 111 students contributing to maths, physics and data analysis in the country

Are you in the Distributed Quantum Computing space? Do you develop hypergraph partitioners? Have you evaluated these partitioners using random circuits? Well, you shouldn’t… Random circuits are a computationally expensive & misleading testbed for partitioner performance: scirate.com/arxiv/2605.0...

On the Distortion of Partitioning Performance by Random Quantum Circuits

Hypergraph partitioning is a central component of distributed quantum computing (DQC) compilers. However, due to the limited size of available quantum benchmark suites, many partitioning studies rely ...

Very excited to have had two papers accepted this week! The camera ready versions should make their way to arXiv by the end of next week :) sites.google.com/view/disqic2...
