Lukasz fidkowski of the university of washington presents "a no go result for implementing chiral symmetries by locality preserving unitaries in a 3 dimensional hamiltonian. Explores limitations in implementing chiral symmetries using locality preserving unitaries for fermionic lattice models, with implications for quantum error correction and quantum gravity.

We argue that the chiral u (1) {a} symmetry of a weyl fermion cannot be implemented by a shallow depth quantum circuit operation in a fermionic lattice hamiltonian model with finite dimensional onsite hilbert spaces. We argue that the chiral $u (1) a$ symmetry of a weyl fermion cannot be implemented by a shallow depth quantum circuit operation in a fermionic lattice hamiltonian model with finite. Grand unified theories are chiral gauge theories. an celebrated no go theorem by nielsen and ninomiya [1] explicitly concluded that the u(1)a symmetry cannot be engineered in a local lattice mo. For our main result, we show that time reversal invariant 3 1d lattice systems (such as dirac and weyl semimetals) can never admit a lone low energy symmetry protected dirac fermion (or node), i.e., it must always come in higher muliplets or be fine tuned. We argue that the chiral u (1)a symmetry of a weyl fermion cannot be implemented by a shallow depth quantum circuit operation in a fermionic lattice hamiltonian model with finite dimensional onsite hilbert spaces.
