QBism: The simplest interpretation of quantum physics
Quantum mechanics is simultaneously our most powerful and weirdest scientific theory. It’s powerful because it offers exquisite control over the nanoworld of molecular, atomic, and subatomic phenomena. It’s weird because, while we have a complete mathematical formalism, we physicists have been arguing for more than a century over what that formalism means. In other words, unlike other physical theories, the mathematics of quantum mechanics has no clear interpretation. That means physicists and...

The end of the quantum tunnel: Exact instanton transseries for quantum mechanics
In the quantum world, processes can be separated into two distinct classes. One class, that of the so-called "perturbative" phenomena, is relatively easy to detect, both in an experiment and in a mathematical computation. Examples are plentiful: the light that atoms emit, the energy that solar cells produce, the states of qubits in a quantum computer.
