Quantum error mitigated classical shadows

H Jnane, J Steinberg, Z Cai, HC Nguyen, B Koczor - PRX Quantum, 2024 - APS
Classical shadows enable us to learn many properties of a quantum state ρ with very few
measurements. However, near-term and early fault-tolerant quantum computers will only be …

Quantum gravity of the Heisenberg algebra

A Almheiri, A Goel, XY Hu - Journal of High Energy Physics, 2024 - Springer
A bstract We consider a simplified model of double scaled SYK (DSSYK) in which the
Hamiltonian is the position operator of the Harmonic oscillator. This model captures the high …

Path integral for chord diagrams and chaotic-integrable transitions in double scaled SYK

M Berkooz, N Brukner, Y Jia, O Mamroud - Physical Review D, 2024 - APS
We study transitions from chaotic to integrable Hamiltonians in the double scaled Sachdev-
Ye-Kitaev (SYK) and p-spin systems. The dynamics of our models is described by chord …

Quantum energy teleportation versus information teleportation

J Wang, S Yao - Quantum, 2024 - quantum-journal.org

energy is activated as extractable work through collaborative local operations and classical …

[PDF][PDF] Deriving the Multi-fold Theory from General Relativity at Planck scale

SH Maes - viXra, 2022 - researchgate.net
In a multi-fold universe, gravity emerges from Entanglement through the multi-fold
mechanisms. As a result, gravity-like effects appear in between entangled particles, whether …

Sparsity-Independent Lyapunov Exponent in the Sachdev-Ye-Kitaev Model

AM García-García, C Liu, JJM Verbaarschot - Physical Review Letters, 2024 - APS
The saturation of a recently proposed universal bound on the Lyapunov exponent has been
conjectured to signal the existence of a gravity dual. This saturation occurs in the low …

Quantum chaos in the sparse SYK model

P Orman, H Gharibyan, J Preskill - arxiv preprint arxiv:2403.13884, 2024 - arxiv.org
The Sachdev-Ye-Kitaev (SYK) model is a system of $ N $ Majorana fermions with random
interactions and strongly chaotic dynamics, which at low energy admits a holographically …

Refined quantum Lyapunov exponents from replica out-of-time-order correlators

DA Trunin - Physical Review D, 2023 - APS
We suggest a new indicator of quantum chaos based on the logarithmic out-of-time-order
correlator. On the one hand, this indicator correctly reproduces the average classical …
