Effects of gate errors in digital quantum simulations of fermionic systems

Jan-Michael Reiner, Sebastian Zanker, Iris Schwenk +4

Digital quantum simulations offer exciting perspectives for the study of fermionic systems such as molecules or lattice models. However, with quantum error correction still being o…

Quantum simulation of the spin-boson model with a microwave circuit

Juha Leppäkangas, Jochen Braumüller, Melanie Hauck +7

We consider superconducting circuits for the purpose of simulating the spin-boson model. The spin-boson model consists of a single two-level system coupled to bosonic modes. In mos…

Analyzing the spectral density of a perturbed analog quantum simulator using Keldysh formalism

Sebastian Zanker, Iris Schwenk, Jan-Michael Reiner +2

Simulation of interacting electron systems is one of the great challenges of modern quantum chemistry and solid state physics. Controllable quantum systems offer the opportunity to…

Reconstructing the ideal results of a perturbed analog quantum simulator

Iris Schwenk, Jan-Michael Reiner, Sebastian Zanker +3

Well-controlled quantum systems can potentially be used as quantum simulators. However, a quantum simulator is inevitably perturbed by coupling to additional degrees of freedom. Th…

Detector Readout of Analog Quantum Simulators

Lin Tian, Iris Schwenk, Michael Marthaler

An important step in quantum simulation is to measure the many-body correlations of the simulated model. For a practical quantum simulator composed of finite number of qubits and c…

Estimating the error of an analog quantum simulator by additional measurements

Iris Schwenk, Sebastian Zanker, Jan-Michael Reiner +2

We study an analog quantum simulator coupled to a reservoir with a known spectral density. The reservoir perturbs the quantum simulation by causing decoherence. The simulator is us…

Distortion of a reduced equilibrium density matrix: influence on quantum emulation

Iris Schwenk, Michael Marthaler

We study a system coupled to external degrees of freedom, called bath, where we assume that the total system, consisting of system and bath is in equilibrium. An expansion in the c…
