Computational Quantum Physicist - EPFL Lausanne, Switzerland
I have a new opening for several funded PHD positions in my group (the Computational Quantum Science Lab, at EPFL). If you are a talented, motivated student, please apply here www.epfl.ch/labs/cqsl/jo.... I am especially looking to hire in scientific ML applications/NQS; not in quantum computing.
Job Opportunities at CQSL
At the Computational Quantum Science Lab we typically have several openings yearly (at the PhD/ Postdoc level). Applications are reviewed twice a year, at the beginning of April and at the beginning o...

Spot the problem(s): you have a numerical technique A for quantum systems that is not variational, you apply it to system X, then compare it to a variational method B previously applied to system Y and you extrapolate it to X. Then, you claim that method B has lower energies than A!
