Walk on the quantum side: caesium atom in a superposition Is there a limit on how large a quantum superposition can be or can macroscopic objects, such as humans or say cats, also exist in a ...

Quantum walks sound abstract, but they sit at the center of a very concrete race: who will harness quantum mechanics to solve problems that overwhelm today’s most powerful supercomputers. Instead of ...

WEST LAFAYETTE, Ind. — A new quantum random walk technique developed by engineers at Purdue University could eventually allow computers to search through data at speeds beyond that of conventional ...
