I think the WIMP interaction process via the models they tested and the data on astrophysical neutrinos from other detectors gives at least several(?) orders of magnitude of separation in the rate at which each would strike the detector. Of

I actually saw one of the authors present the data yesterday, one of the audience comments was indeed that this could be explained by an astrophysical neutrino striking the detector (all other neutrino sources have energy thresholds much lo

I find it strange that it’s so often framed as a competition between classical and quantum computation, when in practice the development for quantum algorithms has led to many advances in classical computing; quantum algorithms require larg

Most of what I use day to day in research is either specialized to my subfield or can be found in Nielsen and Chuang, so I've actually never looked at any other textbooks specifically for quantum computation. If you're interested

1) Generally the two models of QC are the digital/circuit model (analogous to digital logic gates, with some caveats, such as reversibility of operations, no-cloning theorem), and analog computation (tuning the parameters of a continuo

“Perhaps I could best describe my experience of doing mathematics in terms of entering a dark mansion. One goes into the ﬁrst room, and it’s dark, completely dark. One stumbles around bumping into the furniture, and gradually, you learn whe

The hardware very much lags behind the algorithmic advances, much of the current push for new features in quantum hardware (midcircuit measurement/feedforward, phonon mode coupling, etc) often comes from theorist colleagues pestering e

I think the more convincing argument is that most known applications of quantum computers (sidestepping any hardware practicalities), are for niche problems (in my wheelhouse, quantum simulation), the average person has no (practically adva

If you prefer python, tenpy is quite nice for tensor networks as well.

Yeah this seems like a very useful technique for ground state properties, I’m also surprised in retrospect, having never heard of TWA before now.

Reading their paper, it does seem like this method is significantly simpler than using something like MPS, my main concern is the practical coupling regime for which this method works, I would imagine that it would fail closer to critical p

Practically speaking, QM can be taught without the assumption that students understand the Hamiltonian formalism, simply by starting with Hilbert spaces and operators on Hilbert spaces. In fact, I would claim that having taken a class on ba
