Realizing Unitary $k$ -designs with a Single Quench

Yi-Neng Zhou, Robin Löwenberg, Julian Sonner

We present a single-quench protocol that generates unitary $k$ -designs with minimal control. A system first evolves under a random Hamiltonian $H_{1}$ ; at a switch time $t_s \geq t_{…

Measuring Rényi entropy with an Echo Protocol

Yi-Neng Zhou, Robin Löwenberg, Julian Sonner

We present efficient and practical protocols to measure the second Rényi entropy, whose exponential is known as the purity. Our approach is based on expressing the purity in terms…
