Quantum computers need just 10,000 qubits to break the most secure encryption, scientists warn

Future quantum computers will need to be less powerful than we thought to threaten the security of encrypted messages.

Quantum computers need vastly fewer resources than thought to break vital encryption

Building a utility-scale quantum computer that can crack one of the most vital cryptosystems—elliptic curves—doesn’t require ...

Parallel Variational Quantum Algorithms With Gradient-Informed Restart to Speed Up Optimization in the Presence of Barren Plateaus

Abstract: Inspired by the Fleming–Viot stochastic process, we propose a parallel implementation with restart of variational quantum algorithms, with the aim of reducing the time spent by the algorithm ...

Parallel Time-Domain Simulation Algorithm Based on Physics-Informed Neural Networks

Abstract: This letter proposes a parallel physics-informed neural network (PINN) algorithm for solving time-domain electromagnetic simulations. This method first decomposes the global computational ...
