Operation and intrinsic error budget of a two-qubit cross-resonance gate
Vinay Tripathi, Mostafa Khezri, Alexander N. Korotkov
We analyze analytically, semi-analytically, and numerically the operation of Cross-Resonance (CR) gate for superconducting qubits (transmons). We find that a relatively simple semi…

Covariance matrix entanglement criterion for an arbitrary set of operators
Vinay Tripathi, Chandrashekar Radhakrishnan, Tim Byrnes
We generalize entanglement detection with covariance matrices for an arbitrary set of observables. A generalized uncertainty relation is constructed using the covariance and commut…
