All you need is quantum chaos. Except that you do not need #quantumchaos. https://t.co/ME5PZYliWI It took me a while to accept that the main result of this work is not wrong, which I still find surprising.

In this work https://t.co/ISUZUDVhhJ with @Muzhou_Ma, @S_Flammia, and @preskill, we tackle the problem of learning a non-local Hamiltonian with Heisenberg-limited scaling. Specifically, we focus on efficiently learning a k-body Hamiltonian without any geometric structure.

We study the problem of learning a $k$-body Hamiltonian with $M$ unknown Pauli terms that are not necessarily geometrically local. We propose a protocol that learns the Hamiltonian to precision...

MA-hard Hamiltonians now also available locally on your nearest neighbour lattices!
Complexity of geometrically local stoquastic Hamiltonian https://t.co/IESquXCoOe In this work located in the field of #Hamiltoniancomplexity, we show that 1d and 2d geometrically local stoquastic (sign problem free) Hamiltonians are MA-hard with high enough qudit dimension.

Check out this thread on our recent work on online learning quantum processes! Warm thanks to @non_unitary, @IMathYou2, and @jenseisert for an awesome collaboration.
1/6 We all love shadow tomography, where a crucial subroutine is online learning of quantum states. In this work, we extend efficient online learnability of states to (i) any quantum channel with polynomial gate complexity, (ii) arbitrary Pauli channels, and even more!

If you're curious, come to the MathPhys session on Thursday!
Quantum metrology in the finite-sample regime. A talk held at #QIP2024 by @jj_xyz on #quantummetrology that overcomes the need of discussing matters in the asymptotic limit, and introduces what could be called "PAC quantum metrology". CC @SumeetKhatri6, @dsfranca, @phfaist.
