A new #quantumsimulation scheme that unites the advantages of randomized compiling and higher-order multi-product formulas as they are used in linear-combination-of-unitaries. It can be seen as being intermediate between digital and analog simulation. scirate.com/arxiv/2101.078…

BREAKING: President Biden signs executive order banning people from saying “Quantum computers solve problems by just trying all possible solutions in parallel”

After thinking for the 100th time about how to create a list of all bit strings of a given size in Python I decided to put it on GitHub. github.com/frederikwilde/…

Here's a friendly reminder to always contract your high-dimensional indices first. Just spent two days wondering why my memory blows up 🤦‍♂️

print("hello world") # this prints hello world

Hilarious, in'nit? #javascript #Python

My friend made me this to celebrate the handing in of my thesis 😁

Theoretical computer scientists see interaction between an electron on Earth and another one on Mars and call it a 𝙡𝙤𝙘𝙖𝙡 Hamiltonian.

If this was about babies, there would be universal healthcare. Free education. Free daycare. Southern states would be doing all they can to drop the Black maternal mortality rate. This is about power and control

If the Haar measure was defined over beverages instead of groups.

Despite what some seem to believe, this is not an effective PowerPoint slide

12.7 billion people write every day. But 97.56% are doing it wrong. Here are some tips that will change your life for ever 🤯👇

This piece of work is particularly close to my heart. It presents a scalable and highly experimentally friendly method of #Hamiltonianlearning, by combining ideas of #tensornetworks and #machinelearning. It has been in the making for over two years. scirate.com/arxiv/2209.143…

Very happy with our new paper on Hamiltonian learning scirate.com/arxiv/2209.143… We use auto-diff to train a tensor-network based simulator (TEBD) on dynamical measurement data.

Noise is for good reasons seen as the main antagonist to #quantumcomputing. Here, we provide evidence and prove that saddle points can be avoided in #variationalquantumalgorithms by exploiting stochasticity: The right kind of #noise can be helpful. scirate.com/arxiv/2210.067…

Seems like today is quantum dynamics simulation day. Three very interesting methods: Tensor networks arxiv.org/abs/2210.12151 Cluster expansions arxiv.org/abs/2210.11490 Lie-algebra decoupling arxiv.org/abs/2210.11894

Boo! 👻
