Decoherence of Majorana qubits by 1/f noise
Abhijeet Alase, Marcus C. Goffage, Maja C. Cassidy +1
Qubits based on Majorana zero modes (MZMs) in superconductor-semiconductor nanowires have attracted intense interest due to claims that their error rates are suppressed exponential…
Electronically-controlled one- and two-qubit gates for transmon quasicharge qubits
Nicholas M. Christopher, Deniz E. Stiegemann, Abhijeet Alase +1
Superconducting protected qubits aim to achieve sufficiently low error rates so as to allow realization of error-corrected, utility-scale quantum computers. A recent proposal encod…
Excitation of quasiparticle pairs in superconducting nanodevices by 1/f noise
Clare C. Yu, M. C. Goffage, Yifan Wang +3
Superconducting nanodevices such as qubits, resonators, and photodetectors, have revolutionized our capabilities for probing and controlling quantum phenomena. Nonequilibrium quasi…
Leakage at zero temperature from changes in chemical potential in Majorana qubits
M. C. Goffage, A. Alase, M. C. Cassidy +1
Building a fault-tolerant quantum computer requires physical qubits with exceptionally low error rates. Majorana-based tetron qubits are predicted to exhibit error rates that decre…
