Multicritical dissipative phase transitions in the anisotropic open quantum Rabi model
Guitao Lyu, Korbinian Kottmann, Martin B. Plenio +1
We investigate the nonequilibrium steady state of the anisotropic open quantum Rabi model, which exhibits first-order and second-order dissipative phase transitions upon varying th…
Reducing Entanglement With Physically-Inspired Fermion-To-Qubit Mappings
Teodor Parella-Dilmé, Korbinian Kottmann, Leonardo Zambrano +3
In ab-initio electronic structure simulations, fermion-to-qubit mappings represent the initial encoding step of the fermionic problem into qubits. This work introduces a physically…
Evaluating analytic gradients of pulse programs on quantum computers
Korbinian Kottmann, Nathan Killoran
Parametrized pulse programs running on quantum hardware can be differentiated via the stochastic parameter-shift (SPS) rule. We overcome the intrinsically approximate nature of SPS…
