Analog quantum simulation of bosonic and anyonic models with flux-driven transmons
Isak Lyngfelt, Jorge Fernández-Pendás, Göran Johansson +1
When quantum particles interact, many-body phenomena that are hard to simulate classically emerge. Quantum analog simulation offers an alternative in which the target system's dyna…
Mitigating transients in flux-control signals in a superconducting quantum processor
Anuj Aggarwal, Jorge Fernández-Pendás, Tahereh Abad +12
Flux-tunable qubits and couplers are common components in superconducting quantum processors. However, dynamically controlling these elements via current pulses poses challenges du…
Quantum SWAP gate realized with CZ and iSWAP gates in a superconducting architecture
Christian Križan, Janka Biznárová, Liangyu Chen +19
It is advantageous for any quantum processor to support different classes of two-qubit quantum logic gates when compiling quantum circuits, a property that is typically not seen wi…
Comprehensive explanation of ZZ coupling in superconducting qubits
Simon Pettersson Fors, Jorge Fernández-Pendás, Anton Frisk Kockum
A major challenge for scaling up superconducting quantum computers is unwanted couplings between qubits, which lead to always-on ZZ couplings that impact gate fidelities by shiftin…
Extensive characterization of a family of efficient three-qubit gates at the coherence limit
Christopher W. Warren, Jorge Fernández-Pendás, Shahnawaz Ahmed +13
While all quantum algorithms can be expressed in terms of single-qubit and two-qubit gates, more expressive gate sets can help reduce the algorithmic depth. This is important in th…
Building Blocks of a Flip-Chip Integrated Superconducting Quantum Processor
Sandoko Kosen, Hang-Xi Li, Marcus Rommel +24
We have integrated single and coupled superconducting transmon qubits into flip-chip modules. Each module consists of two chips -- one quantum chip and one control chip -- that are…
