There is a type cirq.PauliSum created when you add together products of Pauli operations. This type has a method expectation_from_state_vector and expectation_from_density_matrix. This is the easiest way to get the expectation values, if you're just calculating them instead of estimating them from samples taken from hardware.
Note that both methods require ...

I'm not sure if the 286 qubit estimate has ever been fully explained, but we can backwards reason about how to get to the figure.
First off, accuracy of quantum chemistry simulations via Trotterization is a function of the basis set (in both classical and quantum simulations). The basis set is kinda like a coordinatization the electron orbitals. There are a ...
