High-Fidelity Controlled- Z Gate with Maximal Intermediate Leakage Operating at the Speed Limit in a Superconducting Quantum Processor
Victor Negîrneac,Victor Negîrneac,Hany Ali,Nandini Muthusubramanian,Francesco Battistel,R. Sagastizabal,Miguel S Moreira,Jorge Marques,Wouter Vlothuizen,Wouter Vlothuizen,Marc Beekman,Marc Beekman,Chris Zachariadis,Nadia Haider,Nadia Haider,Alessandro Bruno,Leonardo DiCarlo +16 more
TL;DR: The sudden variant (SNZ) of the net zero scheme realizing controlled-Z gates by flux control of transmon frequency is introduced, compatible with scalable schemes for quantum error correction and adaptable to generalized conditional-phase gates useful in intermediate-scale applications.

R. Sagastizabal,S.P. Premaratne,Berend Klaver,Michiel Adriaan Rol,Victor Negîrneac,Miguel S Moreira,Xiang Zou,Sonika Johri,Nandini Muthusubramanian,Marc Beekman,Chris Zachariadis,V. P. Ostroukh,Nadia Haider,Alessandro Bruno,A. Y. Matsuura,Leonardo DiCarlo +15 more
TL;DR: In this article, a hybrid quantum-classical variational approach motivated by quantum-approximate optimization algorithms was proposed to generate thermofield double states using a gate-based quantum processor, and the fidelity of generated states to the thermal-equilibrium state smoothly varies from 99 to 75% between infinite and near zero simulated temperature.
