Measurement-induced entanglement and teleportation on a noisy quantum processor

2023 · arXiv (Cornell University)

Measurement has a special role in quantum theory: by collapsing the wavefunction it can enable phenomena such as teleportation and thereby alter the "arrow of time" that constrains unitary evolution. When integrated in many-body dynamics, …

Josephson parametric amplifier with Chebyshev gain profile and high saturation

2023 · Physical Review Applied

We demonstrate a Josephson parametric amplifier design with a band-pass impedance-matching network based on a third-order Chebyshev prototype. We measured eight amplifiers operating at 4.6 GHz that exhibit gains of 20 dB with less than …
