Belief Propagation-based Disentanglers for Tensor Network State Preparation
Tomasz Szołdra, Peter Schmelcher
We develop a quantum circuit synthesis method for preparing a class of tensor network states. The scheme applies to states tractable with belief propagation (BP), a tensor network…
Spin Textures and Eigenstate Evolution of Isospectrally Patterned Lattices
Peter Schmelcher
Isospectrally patterned lattices exhibit a composite band structure with a tunable ratio of localized versus delocalized eigenstates that is controlled by the underlying phase grad…
A Unified Local Light-shifts Encoding For Solving Optimization Problems on a Rydberg Annealer
Kapil Goswami, Peter Schmelcher
Combinatorial optimization problems play a central role in computer science with many real world applications. A number of relevant problems remain computationally difficult to sol…
High-fidelity non-adiabatic dark state gates for neutral atoms
Nader Mostaan, Kapil Goswami, Peter Schmelcher +1
Rydberg blockade gates are the most experimentally mature entangling operations in neutral-atom quantum processors, combining fast gate times with simple control, but their perform…
Scalable Preparation of Matrix Product States with Sequential and Brick Wall Quantum Circuits
Tomasz SzoÅdra, Rick Mukherjee, Peter Schmelcher
Preparing arbitrary quantum states requires exponential resources. Matrix Product States (MPS) admit more efficient constructions, particularly when accuracy is traded for circuit…
Simulating Quantum Circuits with Tree Tensor Networks using Density-Matrix Renormalization Group Algorithm
Aditya Dubey, Zeki Zeybek, Peter Schmelcher
Quantum computing offers the potential for computational abilities that can go beyond classical machines. However, they are still limited by several challenges such as noise, decoh…
