Quantum simulation of operator spreading in the chaotic Ising model
Quantum simulation of operator spreading in the chaotic Ising model
There is great interest in using near-term quantum computers to simulate and study foundational problems in quantum mechanics and quantum information science, such as the scrambling measured by an out-of-time-ordered correlator (OTOC). Here we use an IBM Q processor, quantum error mitigation, and weaved Trotter simulation to study high-resolution operator …
