Low crosstalk modular flip-chip architecture for coupled superconducting qubits
Soeren Ihssen, Simon Geisert, Gabriel Jauma +10
We present a flip-chip architecture for an array of coupled superconducting qubits, in which circuit components reside inside individual microwave enclosures. In contrast to other…
Exploring Quantum Annealing Architectures: A Spin Glass Perspective
Gabriel Jaumà, Juan José García-Ripoll, Manuel Pino
We study the spin-glass transition in several Ising models of relevance for quantum annealers. We extract the spin-glass critical temperature by extrapolating the pseudo-critical p…
Hardware-efficient entangled measurements for variational quantum algorithms
Francisco Escudero, David Fernández-Fernández, Gabriel Jaumà +2
Variational algorithms have received significant attention in recent years due to their potential to solve practical problems using noisy intermediate-scale quantum (NISQ) devices.…
Three-Josephson Junctions Flux Qubit Couplings
María Hita-Pérez, Gabriel Jaumà, Manuel Pino +1
We analyze the coupling of two flux qubits with a general many-body projector into the low-energy subspace. Specifically, we extract the effective Hamiltonians that controls the dy…
Design of Novel Coupling Mechanisms between Superconducting Flux Qubits
Gabriel Jaumà
We have analyzed and proposed coupling mechanisms between Three Josephson Junction Flux Qubits (3JJQ). For this, we have developed a numerical method to extract the effective Hamil…
Ultrastrong capacitive coupling of flux qubits
María Hita-Pérez, Gabriel Jaumà, Manuel Pino +1
A flux qubit can interact strongly when it is capacitively coupled to other circuit elements. This interaction can be separated in two parts, one acting on the qubit subspaces and…
