Quantum computing is now within reach, thanks to a major breakthrough in which scientists demonstrate that a key building block of quantum computers, a quantum Fredkin gate, can be assembled.

Researchers have overcome one of the key challenges to quantum computing by simplifying a complex quantum logic operation. They demonstrated this by experimentally realizing a challenging circuit ...

Oxford University researchers have taken a significant step toward large-scale distributed quantum computing by demonstrating the first successful quantum teleportation of a controlled quantum ...

In this paper, the authors show design of quantum ternary equality, less-than, and greater-than comparators on the top of ion-trap realizable 1-qutrit gates and 2-qutrit Muthukrishnan-Stroud gates.

Quantum Circuits, Inc., announced work with NVIDIA technology integrating NVIDIA CUDA-Q programming capabilities into its ...

They used another laser to excite the atoms to a high-energy state to create the CNOT quantum gate between the two atoms, also achieving a property called entanglement in which thestates of the ...

Researchers have developed a new quantum circuit design that could reduce energy consumption in computing by up to 51%.

This diagram illustrates how the team reduces quantum circuit complexity in machine learning using three encoding methods—variational, genetic, and matrix product state algorithms. All methods ...
