Using Quantum Bits to Crunch Chemistry Equations Now More Error-Free Than Ever

In principle, quantum computers should be able to handle exponentially larger and more complex calculations, like those needed to solve the Schrodinger equation, because the qubits that make them up...

The GPU Strikes Back: Math Catches Up to Google’s Quantum Supremacy Claim

In 2019, word filtered out that a quantum computer built by Google had performed calculations that the company claimed would be effectively impossible to replicate on supercomputing hardware. That turned...

Move Over Quantum Computing, Here’s Something Classical That Computes Just Fine

Two physicists, from EPFL and Columbia University, have introduced an approach for simulating the quantum approximate optimization algorithm using a traditional computer. Instead of running the algorithm on advanced quantum...

Google Improves Quantum Error Suppression 100-Fold?

Error mitigation is perhaps the biggest challenge and barrier to implementing practical quantum computing in the era of noisy intermediate scale quantum (NISQ) computers. Last week, Google reported promising use...

IBM, Rigetti, Phasecraft, Oxford QC, China, and More in HPC Wire’s Quantum Roundup

IBM yesterday announced a proof for a quantum ML algorithm. A week ago, it unveiled a new topology for its quantum processors. Last Friday, the Technical University of Denmark released...
