Mitigating crosstalk errors for simultaneous single-qubit gates on a superconducting quantum processor
Jaap J. Wesdorp, Eric Hyyppä, Joona Andersson +61
Single-qubit gates on superconducting quantum processors are typically implemented using microwave pulses applied through dedicated control lines. However, these microwave pulses m…
Crosstalk Dispersion and Spatial Scaling in Superconducting Qubit Arrays
Mohammed Alghadeer, Simon Pettersson Fors, Shuxiang Cao +5
Crosstalk between qubits fundamentally limits the scalability of quantum processors, necessitating physics-based models that can handle the complexity of large qubit arrays. Here,…
Double-Bracket Algorithmic Cooling
Mohammed Alghadeer, Khanh Uyen Giang, Shuxiang Cao +6
Algorithmic cooling shows that it is possible to locally reduce the entropy of a qubit belonging to an isolated ensemble such as nuclear spins in molecules or nitrogen-vacancy cent…
Intrinsic Multi-Mode Interference for Passive Suppression of Purcell Decay in Superconducting Circuits
Mustafa Bakr, Mohammed Alghadeer, Simon Pettersson Fors +6
Decoherence due to radiative decay remains an important consideration in scaling superconducting quantum processors. We introduce a passive, interference-based methodology for supp…
