Infinite-Level Hierarchy of Solvable Quantum Circuits
Michael A. Rampp, Suhail A. Rather, Pieter W. Claeys
Dual-unitary circuits have emerged as a paradigm of exactly solvable yet non-integrable quantum dynamics. Recently, a generalization of dual unitarity attempting to extend the phen…
Graph-State Circuit Blocks control Entanglement and Scrambling Velocities
Chandana Rao, Himanshu Sahu, Aranya Bhattacharya +3
Random circuit models often describe local dynamics using generic two-qubit gates, which have proven successful in capturing entanglement growth and operator spreading in many cont…
The entanglement membrane in exactly solvable lattice models
Michael A. Rampp, Suhail A. Rather, Pieter W. Claeys
Entanglement membrane theory is an effective coarse-grained description of entanglement dynamics and operator growth in chaotic quantum many-body systems. The fundamental quantity…
Construction of perfect tensors using biunimodular vectors
Suhail Ahmad Rather
Dual unitary gates are highly non-local two-qudit unitary gates that have been studied extensively in quantum many-body physics and quantum information in the recent past. A specia…
Absolutely maximally entangled state equivalence and the construction of infinite quantum solutions to the problem of 36 officers of Euler
Suhail Ahmad Rather, N. Ramadas, Vijay Kodiyalam +1
Ordering and classifying multipartite quantum states by their entanglement content remains an open problem. One class of highly entangled states, useful in quantum information prot…
Dual unitaries as maximizers of the distance to local product gates
Shrigyan Brahmachari, Rohan Narayan Rajmohan, Suhail Ahmad Rather +1
TThe problem of finding the resource free, closest local unitary, to any bipartite unitary gate is addressed. Previously discussed as a measure of nonlocality, the distance $K_…
Construction and local equivalence of dual-unitary operators: from dynamical maps to quantum combinatorial designs
Suhail Ahmad Rather, S. Aravinda, Arul Lakshminarayan
While quantum circuits built from two-particle dual-unitary (maximally entangled) operators serve as minimal models of typically nonintegrable many-body systems, the construction a…
Thirty-six entangled officers of Euler: Quantum solution to a classically impossible problem
Suhail Ahmad Rather, Adam Burchardt, Wojciech Bruzda +3
The negative solution to the famous problem of officers of Euler implies that there are no two orthogonal Latin squares of order six. We show that the problem has a solution,…
From dual-unitary to quantum Bernoulli circuits: Role of the entangling power in constructing a quantum ergodic hierarchy
S. Aravinda, Suhail Ahmad Rather, Arul Lakshminarayan
Deterministic classical dynamical systems have an ergodic hierarchy, from ergodic through mixing, to Bernoulli systems that are "as random as a coin-toss". Dual-unitary circuits ha…
Creating ensembles of dual unitary and maximally entangling quantum evolutions
Suhail Ahmad Rather, S. Aravinda, Arul Lakshminarayan
Maximally entangled bipartite unitary operators or gates find various applications from quantum information to being building blocks of minimal models of many-body quantum chaos, a…
