Fig. 2: Quantum hardware results in the absence of phase transitions.
From: First-order phase transition of the Schwinger model with a quantum computer
The description for this figure follows Fig. 1, however the lattice mass here is set to mlat/g = 0, so that we are below the second order phase transition and thus observe no first-order phase transition as expected. Note that the error bars are much smaller than the y-scale and thus, are not visible. The blue circles represent the exact diagonalization, red pluses the noiseless simulations and black crosses the quantum hardware results.
