Truncated Modular Exponentiation Operators: A Strategy for Quantum Factoring

Quanta
Modular exponentiation (ME) operators are one of the fundamental components of Shor's algorithm, and the place where most of the quantum resources are deployed. These operators are often referred to as the bottleneck of the algorithm. I propose a method

Dynamical cluster-based strategy for improving tensor network algorithms in quantum circuit simulations

Physical Review Research
We optimize matrix-product state-based algorithms for simulating quantum circuits with finite fidelity, specifically the time-evolving block decimation (TEBD) and the density-matrix renormalization group (DMRG) algorithms, by exploiting the irregular ...
