Although the potential applications of quantum computing are widespread, a new feasibility study suggests quantum computers ...

Two popular quantum computing algorithms for problems in chemistry may have very limited use even as quantum hardware ...

Those that solve artificially simplified problems where quantum advantage is meaningless. Those that provide no genuine quantum advantage when all costs are properly accounted for. This critique is ...

The JVG algorithm factors RSA and ECC keys using fewer quantum resources than Shor’s algorithm, accelerating the time needed ...

Quantum computers use qubits, which are based on quantum physics, allowing them to solve complex problems far faster than ...

Oracle-based quantum algorithms cannot use deep loops because quantum states exist only as mathematical amplitudes in Hilbert space with no physical substrate. Criticall ...

The federal government has drawn a line: encryption that protects bank transactions, power grids, and classified communications will not survive the arrival of large-scale quantum computers, and the ...

Quantum computing advantages look weaker; classical methods beat a nitrogen-fixing molecule simulation, raising doubts about ...

Building and maintaining a quantum computer is expensive and technically demanding. Most organizations can’t justify purchasing and running their own quantum processors. Cloud providers change the ...

Quantum computing in 2026 still isn't a faster laptop. It doesn't make email snappier, and it won't speed up spreadsheets.

Quantum computing stocks as a class have beaten the market over the last year. Nvidia is quietly integrating some of its core ...
