Multipartite entanglement in the 1-D spin- Heisenberg Antiferromagnet
Varun Menon, Nicholas E. Sherman, Maxime Dupont +3
Multipartite entanglement refers to the simultaneous entanglement between multiple subsystems of a many-body quantum system. While multipartite entanglement can be difficult to qua…
Diabatic Quantum Annealing for the Frustrated Ring Model
Jeremy Côté, Frédéric Sauvage, Martín Larocca +3
Quantum annealing is a continuous-time heuristic quantum algorithm for solving or approximately solving classical optimization problems. The algorithm uses a schedule to interpolat…
Learning efficient decoders for quasi-chaotic quantum scramblers
Lorenzo Leone, Salvatore F. E. Oliviero, Seth Lloyd +1
Scrambling of quantum information is an important feature at the root of randomization and benchmarking protocols, the onset of quantum chaos, and black-hole physics. Unscrambling…
Unscrambling Quantum Information with Clifford decoders
Salvatore F. E. Oliviero, Lorenzo Leone, Seth Lloyd +1
Quantum information scrambling is a unitary process that destroys local correlations and spreads information throughout the system, effectively hiding it in nonlocal degrees of fre…
Qudit entanglers using quantum optimal control
Sivaprasad Omanakuttan, Anupam Mitra, Eric J. Meier +2
We study the generation of two-qudit entangling quantum logic gates using two techniques in quantum optimal control. We take advantage of both continuous, Lie-algebraic control and…
Optimized Telecloning Circuits: Theory and Practice of Nine NISQ Clones
Elijah Pelofske, Andreas Bärtschi, Stephan Eidenbenz
Although perfect copying of an unknown quantum state is not possible, approximate cloning is possible in quantum mechanics. Quantum telecloning is a variant of approximate quantum…
