Optimizing frequency allocation for fixed-frequency superconducting quantum processors
Alexis Morvan, Larry Chen, Jeffrey M. Larson +2
Fixed-frequency superconducting quantum processors are one of the most mature quantum computing architectures with high-coherence qubits and simple controls. However, high-fidelity…
Microscopic Theory of Magnetic Disorder-Induced Decoherence in Superconducting Nb Films
Evan Sheridan, Thomas F. Harrelson, Eric Sivonxay +6
The performance of superconducting qubits is orders of magnitude below what is expected from theoretical estimates based on the loss tangents of the constituent bulk materials. Thi…
Optimized fermionic SWAP networks with equivalent circuit averaging for QAOA
Akel Hashim, Rich Rines, Victory Omole +6
The fermionic SWAP network is a qubit routing sequence that can be used to efficiently execute the Quantum Approximate Optimization Algorithm (QAOA). Even with a minimally-connecte…
Monitoring fast superconducting qubit dynamics using a neural network
G. Koolstra, N. Stevenson, S. Barzili +11
Weak measurements of a superconducting qubit produce noisy voltage signals that are weakly correlated with the qubit state. To recover individual quantum trajectories from these no…
High-fidelity three-qubit iToffoli gate for fixed-frequency superconducting qubits
Yosep Kim, Alexis Morvan, Long B. Nguyen +6
The development of noisy intermediate-scale quantum (NISQ) devices has extended the scope of executable quantum circuits with high-fidelity single- and two-qubit gates. Equipping N…
Hardware-Efficient Microwave-Activated Tunable Coupling Between Superconducting Qubits
Bradley K. Mitchell, Ravi K. Naik, Alexis Morvan +7
Generating high-fidelity, tunable entanglement between qubits is crucial for realizing gate-based quantum computation. In superconducting circuits, tunable interactions are often i…
