When a quantum computer processes data, it must translate it into understandable quantum data. Algorithms that carry out this 'quantum compilation' typically optimize one target at a time. However, a ...

Xanadu reduces the cost of quantum computer 'table lookups' by about a quarter—a trick to write 2 bits into 1 qubit, still a ...

Quantum advantage refers to the point at which a quantum computer solves a clearly defined task faster or more efficiently than any classical computer—or makes it solvable in the first place. For many ...

Quantum computers promise speedups across a sweeping range of problems, from factoring large integers to simulating molecules ...

Conventional quantum algorithms are not feasible for solving combinatorial optimization problems (COPs) with constraints in the operation time of quantum computers. To address this issue, researchers ...

A new theoretical framework separates computational speed from statistical generalization in quantum machine learning, showing that faster quantum algorithms alone do not guarantee better learning ...

Learn about current advancements in quantum sensing technology and what's still to come in the quantum space from experts at ...

The bigger danger may not be a quantum attack today, but encrypted data stolen today and unlocked years later.

Quantum computers still can’t do much. Almost every time researchers have found something the high-tech machines should one day excel at, a classical algorithm comes along that can do it just as well ...
