Fast mixing of the SYK model at high temperatures
Yiyi Cai, Yongtao Zhan, Alexander Zlokapa
The Sachdev-Ye-Kitaev (SYK) model is a strongly interacting fermionic system. Its dynamics are difficult to analyze with Lieb-Robinson bounds and cluster expansions due to its all-…
Optimal Tolerant Testing of Lindbladian Dissipation
Jinge Bao, Yiyi Cai, Zhong-Xia Shang
Quantifying dissipation is essential for controlling quantum noise and characterizing open-system dynamics. In practical experimental settings, residual noise may still persist des…
Optimal detection of dissipation in Lindbladian dynamics
Yiyi Cai
Experimental implementations of Hamiltonian dynamics are often affected by dissipative noise arising from interactions with the environment. This raises the question of whether one…
High-Temperature Fermionic Gibbs States are Mixtures of Gaussian States
Akshar Ramkumar, Yiyi Cai, Yu Tong +1
Efficient simulation of a quantum system generally relies on structural properties of the quantum state. Motivated by the recent results by Bakshi et al. on the sudden death of ent…
Stochastic Error Cancellation in Analog Quantum Simulation
Yiyi Cai, Yu Tong, John Preskill
Analog quantum simulation is a promising path towards solving classically intractable problems in many-body physics on near-term quantum devices. However, the presence of noise lim…
