Victor V. Albert @vva.bsky.social · 04/06/2026Vibe-classified all subgroups of the 4-qubit symplectic group Sp(8,2), up to conjugacy. 657007 classes vs 1369 for 3-qbit, 56 for 2. AFAIK, this is the simple group with the largest classified subgroups [cf arXiv:1306.4820]. Would not be possible without agents. github.com/valbert4/sp8 0120
Victor V. Albert @vva.bsky.social · 20/03/2026It's official: @preskill.bsky.social now at Oratomic, a new Rydberg atom startup led by Dolev Bluvstein and joined by @roberthuang.bsky.social. Exciting times! 2231
Victor V. Albert @vva.bsky.social · 18/03/2026Exciting, scary, and thoughtful session on the future of AI at #apsmarch and possible breakdown of peer review. Matthew D. Schwartz: "AI will keep getting better and better at physics. We will not." 120

Victor V. Albert @vva.bsky.social · 06/12/2025Peter Shor and Bert de Jong hosted our discussion. We discussed ingredients for achieving the elusive practical quantum speedup. Several noted that an asymptotic polynomial speedup may not be enough since constants can prevent it from kicking in at practical parameter regimes. 130
Victor V. Albert @vva.bsky.social · 06/12/2025Dario Gil kicks off 12 parallel roundtable discussions @fermilab.bsky.social quantum symposium by the SQMC center. 250
Victor V. Albert @vva.bsky.social · 10/09/2025David Gross (Cologne) talks about SDP based quantum algorithms. Take home: hidden constants matter. Even if there is an asymptotic speedup in your favorite use case, it may still not be in the parameter regime that is relevant to the problem size you're interested in. 050
Victor V. Albert @vva.bsky.social · 29/08/2025@ox.ac.uk debate by Simon Benjamin & Bálint Koczor, host @mariaviolaris.bsky.social. Motion: "quantum computers will have a greater impact on our lives than conventional ones." Terry Rudolph, Nathan Wiebe, Elham Kashefi vs @jenseisert.bsky.social, @graemesmith.bsky.social, me. Motion defeated 94-72. 1270
Victor V. Albert @vva.bsky.social · 09/06/2025The integer eigenvalues of angular momentum in a 2D space with periodic boundary conditions are scaled by the radius (for sufficiently large radii). Turns out there is a continuum of angular momenta! arxiv.org/abs/2506.03254 062

Victor V. Albert @vva.bsky.social · 13/02/2025ArXiv quant-ph needs to be split up! Paul Ginsparg lists Daniel Gottesman's proposed subcategories at his @aspenphysics.bsky.social talk. He is looking for feedback: please reply, dm, or email. 44616
Victor V. Albert @vva.bsky.social · 11/02/2025Adam Brown at his @aspenphysics.bsky.social talk updates us on the dramatic improvements in LLM performance on technical exams and makes a compelling case that this improvement will continue for another five years. Not one but many Einsteins coming up! 210

Victor V. Albert @vva.bsky.social · 03/12/2024Codewords normalization and overlap are governed by a Gelfand-Kapranov-Zelevinsky (GKZ) hypergeometric function, and we anticipate interesting connections to this deep literature down the road. 161
Victor V. Albert @vva.bsky.social · 03/12/2024Codewords are projected coherent states, unifying many different previously known constructions (pair-cat, two-mode binomial, dual-rail, SU(N) coherent, various repetition codes, some chi-squared codes) while also defining codes from lattices and algebraic varieties. 110
Victor V. Albert @vva.bsky.social · 03/12/2024These CSS-like codes are defined simply from two integer matrices. We can encode qudit, modes, or rotors. Codes can have finite or infinite Fock-state support. 110
