Ashley Montanaro

Co-founder and CEO of Phasecraft, and Professor of Quantum Computation at the University of Bristol. Views my own and not always coherent.

[Ashley Montanaro @quantumashley]

We have multiple open postdoctoral positions in quantum computing theory at the University of Bristol, to work on topics including quantum algorithms, verification of quantum systems, quantum complexity theory, ... - next deadline 18 Jan https://t.co/cisD58Eanw

[Ashley Montanaro @quantumashley]

Thrilled to announce the next stage of our journey. Huge thanks to our stellar team and our amazing investors (@soundboy and many others) - onward to quantum advantage!

[Phasecraft @PhasecraftLtd]

We’ve raised $34M to accelerate our mission to make quantum useful now. Thank you to @pluralplatform , @PlaygroundVC, @novoholdings who co-led this round, and to our returning investors @AlbionVC , @latitudevc and @ParkwalkAdvisor for backing this next chapter.

[Jens Eisert @jenseisert]

The registration deadline of the main event of the year on quantum computing theory in practice (#QCTiP2025) will be #tomorrow, anywhere on Earth.

@jfitzsimons @horizon_quantum @NiccoloDeMasi Congratulations Joe - wishing you all the best!

[QCTiP2025 @QCTiP2025]

Submissions for QCTiP 2025 are now open.

[Ashley Montanaro @quantumashley]

@henryquantum @gregrosent Unfortunately, it turned out that there was a bug in Lemma 2.1, and the overall proof isn't correct. We've withdrawn the paper from the arXiv and are thinking about how to fix it.

[Ashley Montanaro @quantumashley]

@henryquantum Thanks for the kind words! Your recent work on this problem (and that of @gregrosent ) was crucial for us.

[Leo Zhou @leologist]

Can low-depth QAOA provide exponential quantum speedup over the best known classical heuristics on any optimization problems?

Yes! ✅ @quantumashley and I show this in our new paper:

which we did while I was a visiting fellow @PhasecraftLtd! (1/6)

[QCTiP2025 @QCTiP2025]

We are thrilled to announce that the 6th edition of QCTiP will be in Berlin on the 23-25 April!

Let's get them back by giving Kitaev the Turing Award.

@DulwichQuantum Something I particularly like about this example is that the objective function the author has chosen can be minimised using a greedy algorithm :)

[Ashley Montanaro @quantumashley]

@TomGur @Cambridge_Uni Huge congratulations and well deserved!

[Ashley Montanaro @quantumashley]

@LamiLudovico @UvA_Amsterdam @QuSoftAmsterdam Congratulations - well deserved!

[Ashley Montanaro @quantumashley]

@dsfranca Congratulations - very well deserved!

[Ashley Montanaro @quantumashley]

@PaulSkrzypczyk @jenjaminbones Congratulations Dr @jenjaminbones !

[Ashley Montanaro @quantumashley]

@Jun_Gitef17 @fortnow I agree this isn't an obvious assumption! But empirically, it seems to me that LLMs already do a decent job of explaining existing scientific papers. But none (to my knowledge) has come up with a breakthrough result itself.

[Ashley Montanaro @quantumashley]

@jfitzsimons Thanks Joe! Great to see you the other day.

[Ashley Montanaro @quantumashley]

Thrilled that Steve Flammia has joined the Phasecraft team to head up our new US office!

[Phasecraft @PhasecraftLtd]

We’re delighted to welcome @S_Flammia to the Phasecraft team! Steve has joined us to open and lead our first US Office in Washington DC: an exciting new stage in Phasecraft's journey!

Great to be able to promote this modest proposal from @dabacon!
