here is your answer
Not much, as I understand it. Quantum chemistry is quantum mechanics applied on chemistry, while quantum physics is a bit broader. (By “quantum mechanics” some mean a more theoretical focus, compared to quantum physics. And some, as I understand it, use the terms interchangeably.)
I haven’t studied quantum chemistry, but from what I know of quantum mechanics I’d guess a lot of focus is put on electron configuration and mechanisms in chemical reactions. Perhaps also material properties. (Not, for example, quantum entanglement or more theoretical parts of quantum mechanics.)
i hope you understand

hey there here is your answer
Quantum chemistry is applied quantum physics. Quantum physics deals with, well, how quantum mechanics works and how that affects the Universe. Quantum chemistry applies quantum mechanics to complex collections of atoms and how they behave, with an eye toward understanding chemical structure and chemical reactions.
So a quantum physicist may know a great deal more about the underpinnings of physical law and how to go about formulating new physical laws that might have a chance at being correct, but a quantum chemist will likely know a great deal more about how to apply the "basics" (like the Schrodinger Equation and the Dirac Equation) to systems of electrons, nuclei, atoms, and molecules.
A physics course in quantum mechanics will likely talk about idealized systems like potential wells in various configurations. A physics course in atomic physics will talk about the hydrogen atom and maybe about some basic bonds like the double sigma bond in H2, and talk about how degeneracy causes spectral lines to split. That course would be a lead-in to more "advanced" quantum mechanical concepts like Feynman diagrams, the Fermi sea, quantum entanglement, non-demolition measurements, etc. A chemistry course in atomic physics will talk about almost the same things -- but will be a lead-in to far more complex things like carbon covalent bonds, ionic bonds, quantum implementation of van der Waals forces, degenerate systems like benzene rings, the quantum mechanics of phase transitions and bonding physics, etc.
hope it helps you
