Quantum chaos in the sparse SYK model
Patrick Orman, Hrant Gharibyan, John Preskill
The Sachdev-Ye-Kitaev (SYK) model is a system of Majorana fermions with random interactions and strongly chaotic dynamics, which at low energy admits a holographically dual des…
Quantum simulation of gauge theory via orbifold lattice
Alexander J. Buser, Hrant Gharibyan, Masanori Hanada +2
We propose a new framework for simulating Yang-Mills theory on a universal quantum computer. This construction uses the orbifold lattice formulation proposed by Kapla…
Toward simulating Superstring/M-theory on a quantum computer
Hrant Gharibyan, Masanori Hanada, Masazumi Honda +1
We present a novel framework for simulating matrix models on a quantum computer. Supersymmetric matrix models have natural applications to superstring/M-theory and gravitational ph…
The Python's Lunch: geometric obstructions to decoding Hawking radiation
Adam R. Brown, Hrant Gharibyan, Geoff Penington +1
According to Harlow and Hayden [arXiv:1301.4504] the task of distilling information out of Hawking radiation appears to be computationally hard despite the fact that the quantum st…
The Case of the Missing Gates: Complexity of Jackiw-Teitelboim Gravity
Adam R. Brown, Hrant Gharibyan, Henry W. Lin +3
The Jackiw-Teitelboim (JT) model arises from the dimensional reduction of charged black holes. Motivated by the holographic complexity conjecture, we calculate the late-time rate o…
Falling Toward Charged Black Holes
Adam R. Brown, Hrant Gharibyan, Alexandre Streicher +3
The growth of the "size" of operators is an important diagnostic of quantum chaos. In arXiv:1802.01198 [hep-th] it was conjectured that the holographic dual of the size is proporti…
Onset of Random Matrix Behavior in Scrambling Systems
Hrant Gharibyan, Masanori Hanada, Stephen H. Shenker +1
The fine grained energy spectrum of quantum chaotic systems is widely believed to be described by random matrix statistics. A basic scale in such a system is the energy range over…
Are entangled particles connected by wormholes? Support for the ER=EPR conjecture from entropy inequalities
Hrant Gharibyan, Robert F. Penna
If spacetime is built out of quantum bits, does the shape of space depend on how the bits are entangled? The ER=EPR conjecture relates the entanglement entropy of a collection of b…
