These couplings have the potential to impede gate operations and lead to fidelity loss. In this talk, we delve into an investigation of the influence of stray couplings within a multiqubit circuit. We introduce analytical expressions to quantitatively measure these effects, highlighting the essential parameters to mitigate their parasitic impact. We also reveal the feasibility of completely suppressing all stray interactions. Furthermore, our research explores the exciting prospect of achieving multiqubit capabilities surpassing those of traditional two-body interactions. This breakthrough holds promise for enhancing the optimization and overall performance of quantum algorithms. 001034227 536__ $$0G:(DE-HGF)POF4-5214$$a5214 - Quantum State Preparation and Control (POF4-521)$$cPOF4-521$$fPOF IV$$x0 001034227 536__ $$0G:(DE-HGF)POF4-5215$$a5215 - Towards Quantum and Neuromorphic Computing Functionalities (POF4-521)$$cPOF4-521$$fPOF IV$$x1 001034227 536__ $$0G:(DE-HGF)POF4-5221$$a5221 - Advanced Solid-State Qubits and Qubit Systems (POF4-522)$$cPOF4-522$$fPOF IV$$x2 001034227 536__ $$0G:(BMBF)13N15685$$aVerbundprojekt: German Quantum Computer based on Superconducting Qubits (GEQCOS) - Teilvorhaben: Charakterisierung, Kontrolle und Auslese (13N15685)$$c13N15685$$x3 001034227 536__ $$0G:(EU-Grant)101113946$$aOpenSuperQPlus - Open Superconducting Quantum Computers (101113946)$$c101113946$$fHORIZON-CL4-2021-DIGITAL-EMERGING-02$$x4 001034227 7001_ $$0P:(DE-HGF)0$$aVignes, Chloé$$b1 001034227 7001_ $$0P:(DE-Juel1)171686$$aAnsari, Mohammad$$b2 001034227 7001_ $$0P:(DE-HGF)0$$aMartinis, John$$b3 001034227 8564_ $$uhttps://meetings.aps.org/Meeting/MAR24/Session/G48.5 001034227 909CO $$ooai:juser.fz-juelich.de:1034227$$pec_fundedresources$$pVDB$$popenaire 001034227 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)176178$$aForschungszentrum Jülich$$b0$$kFZJ 001034227 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)171686$$aForschungszentrum Jülich$$b2$$kFZJ 001034227 9131_ $$0G:(DE-HGF)POF4-521$$1G:(DE-HGF)POF4-520$$2G:(DE-HGF)POF4-500$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-5214$$aDE-HGF$$bKey Technologies$$lNatural, Artificial and Cognitive Information Processing$$vQuantum Materials$$x0 001034227 9131_ $$0G:(DE-HGF)POF4-521$$1G:(DE-HGF)POF4-520$$2G:(DE-HGF)POF4-500$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-5215$$aDE-HGF$$bKey Technologies$$lNatural, Artificial and Cognitive Information Processing$$vQuantum Materials$$x1 001034227 9131_ $$0G:(DE-HGF)POF4-522$$1G:(DE-HGF)POF4-520$$2G:(DE-HGF)POF4-500$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-5221$$aDE-HGF$$bKey Technologies$$lNatural, Artificial and Cognitive Information Processing$$vQuantum Computing$$x2 001034227 9141_ $$y2024 001034227 920__ $$lyes 001034227 9201_ $$0I:(DE-Juel1)PGI-2-20110106$$kPGI-2$$lTheoretische Nanoelektronik$$x0 001034227 980__ $$aconf 001034227 980__ $$aVDB 001034227 980__ $$aI:(DE-Juel1)PGI-2-20110106 001034227 980__ $$aUNRESTRICTED
