Xanadu Quantum Technologies Inc. (“Xanadu”), a leading photonic quantum computing company, has today announced a novel quantum computational algorithm to accelerate the discovery and analysis of ...

After 30 months of fast-paced innovation in quantum algorithms, six research groups are hoping to hit paydirt. But there can be only one big winner—if there is a winner at all.

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

Right now, quantum computers are small and error-prone compared to where they’ll likely be in a few years. Even within those limitations, however, there have been regular claims that the hardware can ...

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

A search problem refers to the task of finding a solution within some space of possible options, and that space could be made up of discrete steps or continuously varying values. For example, solving ...

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 ...

The parity-identification problem fits naturally into this landscape. Parity is a global property, insensitive to most local details. In this respect, it resembles many other quantities studied in ...
