Postdoctoral theoretical physicist pondering on the quantum-to-classical transition at The Ohio State University
Wow, the quant-ph arXiv overflow today is really something.
Glad my last PhD related preprint escaped the "noise" (pun intended) by being up earlier this week. Of course I can't resist plugging it again: scirate.com/arxiv/2510.0...
We show incoherent control (via PMP) of noisy radical-pair spins.

This is "framable poster" worthy.
Using this tool, we uncover a surprising result:
quantum resources usually linked to bosonic advantage — non-Gaussianity and symplectic coherence — can actually make classical simulation easier in the presence of noise.

After stretching a bit last year, this year the Nobel committee was determined to give the prize to the physicsiest physics that ever physicsed.
Breaking News: The Nobel Prize in Physics was awarded to John Clarke, Michel Devoret and John Martinis for their work in quantum mechanics.

Little sis making big strides!
Am overjoyed to share that my team was awarded 1st prize for this year's UK National Quantum Computing Centre Hackathon!
Earlier last month, I also contributed a flash talk for the Foundations of Quantum Computing (FQC) 2025 workshop, results now being written up into a preprint.
Watch this space!

New preprint just dropped!
Took quite a while for this one to get to the finish line, but super fulfilling to take this from an initial seed of an idea from during the early part of my PhD all the way to a concrete study.

Interradical motion can push magnetosensing precision towards quantum limits
Magnetosensitive spin-correlated radical-pairs (SCRPs) offer a promising platform for noise-robust quantum metrology. However, unavoidable interradical interactions, such as electron-electron dipolar ...

What is common knowledge in your field but shocks outsiders?
Quantum computers are useful for a very limited set of questions and those questions are mostly of interest to physicists and chemists.

It's been over a hundred years since we first realized that quantum mechanics is a thing, but we still don't actually understand what it *means* about the nature of our universe.
(Though we can predict the output of experiments fine.)

Still gathering my thoughts after coming back from #Helgoland2025, in a nutshell: it certainly was special. Can’t resist sharing a little sneak peak with Časlav Brukner’s priceless old “Balkan” grandma joke (but am keeping Steven Girvin’s equally entertaining “half the time” quip to myself).

Latest paper is out, started as Wenhao’s masters project @dondersinst.bsky.social, then completed during his @euerasmusplus.bsky.social supported visiting studentship @lsiexeter.bsky.social. Findings challenge prevailing principles thought to underly room temperature emergence of bosonic statistics.
Fr\"ohlich versus Bose-Einstein condensation in pumped bosonic systems
Magnon condensation, which emerges in pumped bosonic systems at room temperature, continues to garner great interest for its long-lived coherence. While traditionally formulated in terms of Bose-Einst...

Caught up with new season of Black Mirror. Brilliant 1st episode, but the 2nd episode’s wildly inflated perception of a quantum computer (+Everettian multiverse), rendering one a “deus ex machina” in the literal sense, goes beyond the ludicrousness of even last season’s infamous “qomputer” episode.

And while @hyperboieva.bsky.social celebrates 100 citations (a superb achievement!), I am contented and grateful for having recently reached a humble 20.
Surely again, many at my earlier stage have done better. But it warms my heart that >1 others out there find something worthwhile in my work.
