Hardware-efficient learning of quantum many-body states
Katherine Van Kirk, Jordan Cotler, Hsin-Yuan Huang +1
Efficient characterization of highly entangled multi-particle systems is an outstanding challenge in quantum science. Recent developments have shown that a modest number of randomi…
Quantum Scars in Quantum Field Theory
Jordan Cotler, Annie Y. Wei
We develop the theory of quantum scars for quantum fields. By generalizing the formalisms of Heller and Bogomolny from few-body quantum mechanics to quantum fields, we find that un…
The Complexity of NISQ
Sitan Chen, Jordan Cotler, Hsin-Yuan Huang +1
The recent proliferation of NISQ devices has made it imperative to understand their computational power. In this work, we define and study the complexity class , wh…
Information-theoretic Hardness of Out-of-time-order Correlators
Jordan Cotler, Thomas Schuster, Masoud Mohseni
We establish that there are properties of quantum many-body dynamics which are efficiently learnable if we are given access to out-of-time-order correlators (OTOCs), but which requ…
Learning quantum systems via out-of-time-order correlators
Thomas Schuster, Murphy Niu, Jordan Cotler +3
Learning the properties of dynamical quantum systems underlies applications ranging from nuclear magnetic resonance spectroscopy to quantum device characterization. A central chall…
A precision test of averaging in AdS/CFT
Jordan Cotler, Kristan Jensen
We reconsider the role of wormholes in the AdS/CFT correspondence. We focus on Euclidean wormholes that connect two asymptotically AdS or hyperbolic regions with $\mathbb{S}^1\time…
The Universe as a Quantum Encoder
Jordan Cotler, Andrew Strominger
Quantum mechanical unitarity in our universe is challenged both by the notion of the big bang, in which nothing transforms into something, and the expansion of space, in which some…
Renormalization Group Flow as Optimal Transport
Jordan Cotler, Semon Rezchikov
We establish that Polchinski's equation for exact renormalization group flow is equivalent to the optimal transport gradient flow of a field-theoretic relative entropy. This provid…
