Subspace-selective unitary manipulation based on the Hilbert-space symmetric structures in the multiple-quantum operator algebra spaces in the quantum-computing speedup theory
Announce Type: cross Abstract: The quantum-computing speedup theory considers the symmetric structures and properties of quantum systems as the fundamental Quantum-Computing-Speedup (QCS) resources which are responsible for exponentially speeding up quantum computing and simulating. At present a large and important problem is how to make use of the fundamental QCS resources to speed up essentially quantum computing and simulating. Here the author makes a great effort toward solving this...

Atom-based quantum computers are catching up in the race to usefulness
The race to build the first truly useful quantum computer just got more exciting. A quantum computer made from extremely cold atoms has now passed some of the most important milestones towards usefulness, joining a small group of equally able and promising machines. Though there is wide agreement that sufficiently powerful quantum computers would transform our ability to discover new materials and drugs, and break the encryption that underpins the internet, there are many competing ideas...
Predictive surrogates could cut quantum computing measurement overhead by more than 99.97%
June 6, 2026 feature Predictive surrogates could cut quantum computing measurement overhead by more than 99.97% Ingrid Fadelli Author Sadie Harley Scientific Editor Robert Egan Associate Editor Quantum computers, systems that process information leveraging quantum mechanical effects, have the potential of outperforming classical computers on some tasks. Despite their potential, the use of these systems remains very limited, due to their high cost and other challenges that have so far...
Quantum Mechanical Studies of Photodissociation Dynamics on Quantum Computers
Announce Type: cross Abstract: Theoretical quantum dynamics calculations scale deeply with system size, rendering classical calculations intractable for complex systems. While quantum computing offers a natural solution, its application to nuclear quantum dynamics remains scarce. Here, we present a quantum algorithm to study photodissociation dynamics on quantum computers, benchmarked on the NOCl molecule.
Microsoft, Atom Computing, EeroQ update their quantum computing progress
With dozens of companies, from small startups to tech giants, pursuing quantum computing, there's a steady flow of results as they try to find a path to utility. We typically focus on new technologies and major landmarks, which can obscure the fact that any big success will inevitably have been built on a lot of incremental progress. The past few weeks have seen a number of companies release progress reports on how they're trying to get the technologies closer to general use.

Microsoft’s next-gen quantum chip cuts timeline to useful quantum computing
Microsoft’s new Majorana 2 quantum chip. Microsoft Microsoft claimed last year that it had made a key breakthrough in quantum computing with Majorana 1, the company's first quantum processor. While physicists were immediately skeptical of Microsoft's claims, the software giant is announcing Majorana 2 today, the next generation of its topological quantum chip.
Honeywell's Quantinuum heads for Nasdaq debut as quantum computing gains momentum
Honeywell's Quantinuum heads for Nasdaq debut as quantum computing gains momentum June 4 : Honeywell's Quantinuum is set to make its U.S. market debut later on Thursday, after strong investor interest helped the quantum computing company raise $1.68 billion in an upsized initial public offering. Breakthroughs in the fast-growing technology have spurred bets that quantum machines could eventually outperform conventional computers on certain complex tasks. Sentiment was also buoyed after the...
