Tunable quantum logic gate on photonic qubits with a ladder emitter

2022 · Applied Physics Letters

We describe how a ladder emitter can implement a tunable quantum logic gate on photonic qubits encoded in the frequency basis. The ground-to-first excited state of the ladder emitter interacts with the control photon, and …

Quantum Fourier Transform using Dynamic Circuits

2024 · arXiv (Cornell University)

In dynamic quantum circuits, classical information from mid-circuit measurements is fed forward during circuit execution. This emerging capability of quantum computers confers numerous advantages that can enable more efficient and powerful protocols by drastically reducing …
