We demonstrate mesoscopic transport through quantum states in quasi-1Dlattices maintaining the combination of parity and time-reversal symmetries bycontrolling energy gain and loss. We investigate the phase diagram of thenon-Hermitian system where transitions take place between unbroken and broken$\mathcal{PT}$-symmetric phases via exceptional points. Quantum transport inthe lattice is measured only in the unbroken phases in the energy band-but notin the broken phases. The broken phase allows for spontaneous symmetry-brokenstates where the cross-stitch lattice is separated into two identical singlelattices corresponding to conditionally degenerate eigenstates. Thesedegeneracies show a lift-up in the complex energy plane, caused by thenon-Hermiticity with $\mathcal{PT}$-symmetry.
